The experienced detectorists at Minelab have put together a comprehensive list of FAQs on how to use a metal detector. These also contain many pro tips for metal detecting.
You may find the answers to your questions by reading the FAQs here and from the related Knowledge Base Articles. Of course, if, after searching through this information you still have a question, there please contact our customer service team.
Yes, Minelab metal detectors have the ability to ‘discriminate’ between different types of targets. The discrimination feature on Minelab detectors measure two target properties, ferrous properties and conductive properties.
Ferrous properties refer to how much iron is in a target and therefore how strongly it’s attracted to a magnet. Ferrous targets tend to be trash, so can be discriminated/masked out based on their ferrous properties alone by the detector. Conductive properties refer to how well a target conducts electrical current and therefore responds to a metal detector’s magnetic field. Trash like nails and foil have different conductive properties to valuable targets like coins and rings. In this case the metal detector can make a judgement as to whether the target is trash based on conductivity.
The process for configuring the discrimination settings and the method used to indicate treasure or trash varies across the Minelab range of detectors.
As a rule of thumb, the lower the frequency used by the detector, the deeper it can penetrate the ground. At low frequencies however, sensitivity to small low conductive targets is reduced. The higher the frequency, the higher the sensitivity to small targets, but will not penetrate as deeply. In general, gold detectors operate at higher frequencies (to find small nuggets), while coin and treasure detectors work at lower frequencies for deeper penetration. The exception to this is MPS type metal detectors that are sensitive and deep seeking simultaneously.
The size of a search coil can influence the detection depth or sensitivity of a metal detector. The larger the coil, the deeper it detects, but will have less sensitivity to small targets. Conversely the smaller the search coil’s diameter, the more sensitive it becomes but looses detection depth.
Smaller coils are lighter, easier to control and may be chosen for their ability to negotiate difficult terrain or undergrowth. They are also an advantage in areas of high trash.
The most common coil shapes are conventional solid round coils, elliptical shaped coils and the open web coils. The main reason for the change in shape is to conform to a physical requirement, i.e. an elliptical coil can be pushed around bushes or between rocks easier than a round coil and open web coils move through water easier and are lighter. Conventional round coils are often more stable and perform better and are particularly popular for gold prospecting.
The three most common types of coil windings are Concentric, Double-D, and Monoloop. The difference between these coil types is the pattern the wire is wound within the search coil.
A Concentric coil has an inner circle and an outer circle wire winding. Its search pattern is cone shaped and can be useful for accurately pinpointing a target. Concentric coils tend to be noisier in highly mineralised ground and require more over lap of sweep for thorough ground coverage.
Double-D coils are the preferred coils for most detecting. They give a blade or chisel shaped signal that covers the ground more uniformly and once an operator becomes accustomed to the signal, pinpointing can be very accurate. Double-D coils are also preferred for their superior ground balancing ability.
Monoloop coils have one winding of wire around the circumference of the coil, which is used to both transmit and receive. The signal pattern of the Monoloop coil is cone shaped, requiring more overlapping. In extremely heavily mineralised grounds they can be more difficult to ground balance, however they tend to provide slightly better depth than the Double-D coils.
Dirt, dust and moisture can be trapped inside the skidplate leading to false signals and poor performance. To maintain peak performance of your Minelab detector, it is recommended to clean out the skidplate quite regularly.
Check the coil selection guide to find the most suitable coil for your detecting needs.
Headphone specifications are not really critical in a metal detector as their audio circuitry does not produce Hi-Fi quality sound. e.g. Our detectors frequency output range is only circa 75 -1200Hz
Our audio circuits will drive most headphones from 16 - 100 + ohms.
Audio optimisation is also very subjective as everybody hears differently.
We endeavour not to confuse our customers with unnecessary technical specs because in reality there is no honest way to determine what headphones are best for you other than to try them.
If you have a detector with adjustable audio tones, such as a CTX 3030, we would also recommend you spend some time to ensure the detection tones are optimised for your hearing needs.
There is no specific answer to this question as it depends on the target size, orientation, metallic content, ground minerals and conductivity, electrical and ambient noise in the area and etc.
However we commonly hear of GPX Series detectors finding large gold nuggets at 3 and sometimes 4 feet deep, and CTX 3030s finding coins and rings at over 12 inches.
Only if it becomes faulty.
On some detectors you don’t need to ground balance at all. On others, users new to detecting are recommended to use the Ground Balance Tracking function.
In Tracking, the detector will automatically ground balance for you and remain in balance even if the ground minerals vary. On manual ground balance detectors like the X-TERRA 305 and X-TERRA 505, you need to ground balance at the start of every hunt, and re-balance periodically as required. Always ground balance on clean ground, away from metal objects.
Gold chains are very difficult to detect, particularly very fine chains. Each link of a chain can be very small and the detector sees each link as a separate target, so it can easily be missed. You are more likely to detect the actual clasp or any pendants that may still be on the chain as these are much larger than the individual chain links. High frequency detectors such as the Eureka Gold, or an X-TERRA 705 with an 18.75 kHz coil in prospecting mode, will often pick up fine chains better than most coin detectors.
Coke is carbon and as such can be quite conductive, just like a coin.
The GPZ 7000 is our deepest detector in all ground conditions and can detect through even highly mineralised rock.
No, cable characteristics are matched to coil windings at manufacture, so extending the cable will reduce the performance of the coil.
Smaller coils are better for trashy sites, as they reduce the instances of detecting multiple targets at once. Concentric coils are generally better than Double-D coils for this same reason.
Check the coil selection guide to find the most suitable coil for your detecting needs.
Metal detectors pick up electromagnetic signals from underground metal objects. Similar signals can also be received through the air from other electromagnetic sources, such as power lines, radio transmitters, generators, etc.
If your detector is noisy when you are detecting, but goes quiet when you stop sweeping the coil, then it is receiving signals from mineralized ground. Perform a ground balance and continue detecting.
GPX series only: if it is still noisy then you may need to try an alternate soil/timing selection. All other detectors: if it is still noisy you would need to reduce your sensitivity to the highest stable sensitivity level.
The only guaranteed way to get every possible good target is to use no discrimination. However, digging every target can waste lots of time. Discrimination patterns are always a compromise between digging most good targets and ignoring most junk targets.
This can be caused by a number of reasons:
Usually because you are lifting the coil at the end of your swing. Always sweep slow, low and level for the entire swing.
The Multi-IQ engine in all EQUINOX series is the same, there are however processor enhancements in the EQUINOX 700 and EQUINOX 900 that allow the detector to provide users with better Iron Bias, target separation and discrimination depth.
Park 1 (General/Coins)
Park 1 is optimised for modern coins and larger jewellery with a default discrimination pattern set to reject many common aluminium foil-like targets. Therefore, this is the ideal Profile to start with to learn EQUINOX before experimenting with the other Modes and more specialist settings. Park 1 Multi-IQ processes a lower frequency weighting of the multi-frequency signal, as well as using algorithms that maximise ground balancing for soil to achieve the best signal-to-noise ratio. Hence Park 1 is most suited for general detecting and coin hunting.
Park 2 (Fine jewellery)
Park 2 is ideal for smaller targets in trash-infested (including ferrous trash) locations. It will detect a wider range of targets including low conductor (or higher frequency) targets, e.g. fine jewellery. All non-ferrous targets are accepted by default. Recovery Speed is increased to clearly identify good targets masked by iron trash. Target Tone is set to maximum to provide as much target information as possible via audio. Park 2 Multi-IQ processes a higher frequency weighted multi-frequency signal while ground balancing for soil.
Field 1 (Coins and Artefacts)
Field 1 is for general hunting with high trash rejection. This assists in locating desired targets more easily. The default discrimination pattern is set to reject most coke signals. The first Tone Break is set so that the coke signals will produce the same low tone as ferrous targets. Field 1 Multi-IQ processes a lower frequency weighted multi-frequency signal, as well as using algorithms that maximise ground balancing for soil, to achieve the best signal to noise ratio. Hence being most suited for general detecting and coin hunting.
Field 2 (Fine coins and Artefacts)
Field 2 suits locations with high target and trash densities. It will better detect small hammered coins on their edge or at greater depth. The default discrimination pattern is set to reject most coke signals. Target Tone is set to maximum to enhance audio identification and Recovery Speed is faster. The first Tone Break has been set so that the coke signals will produce the same low tone as ferrous targets. Field 2 Multi-IQ processes a higher frequency weighted multi-frequency signal while ground balancing for soil.
Beach 1 is most useful for detecting in wet or dry beach sand and also in shallow water where conductive salt signals are prevalent. It has good sensitivity to coins and small/large jewellery. Beach 1 reduces the salt signal, while maintaining high transmit power, and still being sensitive to desirable targets. Beach 1 Multi-IQ processes a low frequency weighted multi-frequency signal, and uses special algorithms to maximise ground balancing for salt
Beach 2 gives the best results when either wading or shallow diving with the coil and/or detector fully submerged. In these instances, there is a very strong salt signal present, so Beach 2 has a lower transmit power, which results in much less noise. This profile may also be useful in dry conditions where there are extremely high ground noise levels. Beach 2 Multi-IQ processes a very low weighted multi-frequency combination, using the same algorithms as Beach 1 to maximise ground balancing for salt.
Multi-IQ (EQUINOX 800 & 900 only)
Gold 1 is suitable for searching for small gold nuggets in ‘mild’ ground. Most goldfield locations have a variable level of iron mineralisation that will require an ongoing Ground Balance adjustment, therefore Tracking Ground Balance is the default setting. The audio Threshold Level and Threshold Pitch are optimised for hunting for gold nuggets. Gold 1 Multi-IQ processes a high frequency weighted multi-frequency signal, while ground balancing for mineralised soil.
Gold 2 is best for searching for deeper gold nuggets in ‘difficult’ ground conditions. Gold 2 has a lower Recovery Speed, which will increase detection depth. However, more ground noise in more heavily mineralised grounds may result. Tracking Ground Balance is the default setting. The audio Threshold Level and Threshold Pitch are optimised for hunting for gold nuggets. Gold 2 Multi-IQ processes a high frequency weighted multifrequency signal, while ground balancing for mineralised soil.

The new carbon fiber shaft design allows users to pack the detector down to 61cm (24 in) and has a full extension of 144cm (56.7 in)
Depth performance will differ depending on conditions and detector settings. Beach performance is better overall. Enhancements have been made to improve recovery speed, target separation and discrimination depth allowing users to have solid target IDs at better depths. EQUINOX 900 comes with 28 levels of sensitivity allowing more depth where environmental conditions allow the sensitivity to be turned up.
What are the frequency differences between the EQUINOX 600, 700, 800 & 900?
The EQUINOX 600 and 700 offer a choice of 4 single selectable frequencies:
• 5 kHz
• 10 kHz
• 15 kHz
The EQUINOX 800 and 900 offers the choice of 6 single selectable frequencies:
• 5 kHz
• 10 kHz
• 15 kHz
• 20 kHz
• 40 kHz
Gold Mode is designed to enhance performance on small gold nuggets in mineralized ground. It does so primarily by using different audio processing so that targets respond both in volume and pitch. The Gold Mode will be of interest to gold prospectors but has less application for other uses.
While the EQUINOX 600 and 700 do not have a dedicated Gold prospecting mode. Multi-IQ is so good in both Park 2 and Field 2, that these profiles are as good, or better, at finding gold nuggets than many dedicated single-frequency gold detectors. Multi-IQ provides very stable ID’s which is great for choosing what targets to dig in a goldfield.
Iron Bias is a setting that lets you choose how you want iron in the ground to sound. If you have a low setting, more of the iron will come through as a good target to dig up. This will also give you the best chance of finding any valuable non-ferrous targets nestled among the iron.
However, if you desire to hear less false audio sounds from the iron in the ground, try increasing the Iron Bias setting.
The Iron Bias in the EQUINOX 700 and EQUINOX 900 has had some changes to improve discrimination depth.
EQUINOX 600 and 800 have the option to choose either FE Iron Bias or F2 Iron Bias. FE Iron Bias will provide control over the target ID response. F2 Iron Bias will provide tone and target ID response adjustment for a wider range of ferrous targets.
Iron Bias in the EQUINOX 700 and EQUINOX 900 is based off the F2 Iron Bias in the EQUINOX 600 and EQUINOX 800 but allows even better overall depth detection and target separation. Because of this there is no F2 option available in the EQUINOX 700 or EQUINOX 900.
- EQX06 / EQX|06 (6” round Double-D coil)
- EQX11 / EQX|11 (11” round Double-D coil)
- EQX15 / EQX|15 (15”x12” Double-D coil)
No, they have different technology requirements and are not compatible. Only Minelab EQX coils are compatible with EQUINOX series detectors.
Having a larger target ID scale allows the detector to provide the user with more information on the target prior to digging it. This allows users to identify more targets individually which will help determine if the target is valuable or trash.
In general, Multi is superior to the single frequencies when using an EQUINOX. However, there may be specialised situations where a particular frequency has a unique advantage. The EQUINOX Series offers users simultaneous Multi-Frequency plus a wide range of single selectable frequencies for specialist situations.
Yes, there is no need to perform a full factory reset. Individual Search Profiles can easily be returned to their factory preset settings. Only the local settings will be reset and any global settings will remain in their last-use state.
Beach Mode automatically senses black sand and reduces the transmit power to ensure that targets can still be detected without overloading occurring. When black sand is sensed, the Beach Overload Indicator will appear on the LCD. When this icon disappears, full transmit power automatically resumes.
Depth Pitch is an audio mode that provides a continuous pitch audio with no threshold tone. It provides separate audio for ferrous and non-ferrous targets with a variable pitch.
Small or deep targets providing a weaker signal will have a lower pitch.
Large or shallow targets providing a stronger signal will have a higher pitch.
EQUINOX 700 and EQUINOX 900 have been designed to handle harsh outdoor environments. Our testing includes drop tests up to 1m, flex and water ingress testing. Both models are IP68 rated and can be submerged up to 5m (16ft)
Middle and Lower shafts can be mixed. They are not identical in size so they may not provide an exact fit. Upper shafts cannot be changed as the physical mounting point of the control pod is different.
The supplied magnetic USB charge cable can be used on all models in the EQUINOX series.
The charge time, from completely flat to 100%, is approximately 4 hours when charged with a high capacity charger (>1.7A @ 5V).
• Avoid charging or using in extreme temperatures.
• Avoid rapid extreme temperature swings.
• Use only Minelab or Minelab recommended USB chargers and avoid so-called ultrafast chargers from third-parties that claim to fully charge Li-ION batteries in less than one hour.
• Before storing the detector for prolonged periods, the battery should be charged to approximately 50-60%. On the EQUINOX Battery Status Indicator, 2-bars is the optimum charge for prolonged storage. Maintaining the 2-bar charge periodically during extended storage is also advisable. Extended storage in temperatures less than 30oC (86’F) will also minimize degradation to Li-ION battery life
Use only reputable and certified USB Chargers when charging the EQUINOX battery as detailed below:
The EQUINOX detectors support charging from devices that comply to the USB 2.0 standard. QuickCharge™ is a proprietary standard develop by Qualcomm that uses a higher voltage and is not compatible with EQUINOX detectors.
The Li-ION battery contained in the handle is replaceable and covered under warranty for a period of 1 year (12 months) from the date of purchase. Minelab recommends using an Authorised Service Centre to avoid potentially damaging the waterproof seal and voiding the detector warranty.
*EQUINOX 600 and EQUINOX 800 batteries are not compatible with the EQUINOX 700 or EQUINOX 900.
You can charge your EQUINOX detector by using a USB power bank when detecting on land, without any limitations. However, the detector must not be used underwater whilst charging or when connected to a power bank.
If the EQUINOX battery is flat connecting to a power bank will allow you to continue to use the detector. If there is spare capacity in the power bank it will both power and charge the detector.
Typical runtime, from a full charge using wired headphones, is approximately 12 hours. The EQUINOX Series detectors can also be powered directly from any USB Power Bank that supports 0.5A or 2A (@ 5V) output capability. This effectively gives a continuous runtime only limited by the power banks being used.
Longevity for all batteries depends on a number of factors that are often controllable to some degree by the user; such as temperature, charge levels when stored, charge cycles etc. The most common cause of reduced life of Li-ION batteries is keeping a fully charged battery at elevated temperatures.
As with all components used in our detectors, we stringently source only modern high quality components from responsible vendors. We do not expect users to experience any battery issues over years of use. Our experience with the CTX 3030 and GPZ 7000 detectors which both use Li-ION batteries is that the vast majority of users have never needed to purchase a replacement battery.
Yes. If the detector is being used, when powered by a USB power bank, the battery may charge at a slower rate if there is enough spare capacity in the power bank.
Yes. Connecting your Equinox to a power bank will allow you to continue to use it even if the battery is low/flat. The power bank will charge the detector, which will continue operating as normal.
Yes. Connecting the WM 08 to a power bank will allow you to continue to use it even if the battery is low/flat. The power bank will charge the WM 08, which will continue operating as normal.
*Please note that the WM08 is not compatible with the EQUINOX 700 OR EQUINOX 900
No. They are separate wireless technologies and only one can be used at any one time.
*Please note that the WM08 and Bluetooth headphones are not compatible with the EQUINOX 700 OR EQUINOX 900
Re-pairing will be required if a different wireless device has been connected to the Equinox 600 or Equinox 800 (e.g. WM 08), or following a detector factory reset.
Bluetooth® Hearing Aids are largely intended to allow the wearer to intentionally connect to other Bluetooth® compatible devices, such as phones and audio streams. They enable the wearer to stream audio on-the-go without having to remove the hearing aid and insert earbuds.
The EQUINOX 600 and EQUINOX 800 detectors are Bluetooth® compatible devices.
While there are various different types of streaming audio hearing aids available on the market, if the hearing aid supports Bluetooth® A2DP or Bluetooth® aptX-Low Latency™ then it will be compatible with the EQUINOX 600 and EQUINOX 800 detectors.
Pairing with the EQUINOX 600 or EQUINOX 800 is achieved by pressing and holding the Wireless button on the side of the Control Unit for 5 seconds.
While pairing is being performed the Wireless icon on the LCD will flash rapidly for 15 seconds. After 15 seconds the Bluetooth® icon will start flashing on the LCD to indicate a Bluetooth device is being paired.
The initial pairing may take up to 5 minutes. During the pairing process the user should not press the Wireless button as this will stop the pairing process.
Once paired, the EQUINOX 600 or EQUINOX 800 will display a solid Bluetooth® icon on the top right of the LCD. If the hearing aid is aptX-Low Latency™ Bluetooth compatible the ‘+’ icon will also be displayed.
Consult your Hearing Aid User Manual for additional pairing instructions specific to your hearing aid.
*Please note that EQUINOX 700 and EQUINOX 900 are not currently compatible with hearing aids.
Yes, the Equinox 600 can still pair to Bluetooth A2DP or Bluetooth aptX-Low Latency headphones.
Yes. It is good practice to wash the detector with clean fresh water after detecting in water or on the beach. Never use abrasives or solvents to clean the detector.
Whenever washing or using your detector underwater always ensure that the plastic bung on the rear of the control pod is firmly screwed into the headphone jack.
No. It is not necessary to lubricate or grease any part of the detector, including the waterproof seals. Using any petroleum-based grease will damage the waterproof seals and void the warranty.
If deep wading or fully submerged, we recommend using only Minelab Waterproof EQUINOX Headphones. These have a specially engineered connector that forms a waterproof seal when used with the EQUINOX. These headphones are available as an accessory from your local Minelab authorised dealership (Part Number: 3011-0372)
GeoSense-PI™ technology analyses and responds to ground signals with great clarity and precision, so you can detect in difficult environments once thought undetectable. It rapidly suppresses unwanted signals via three overlapping feedback systems for superfast detection of even the tiniest gold pieces.
The GPX 6000 is our best performer on the more plentiful smaller nuggets, even in highly mineralised or variable ground. It retains excellent depth, just behind the GPZ 7000 on larger, deeper nuggets.
The GPX 6000 coils are a new range of lightweight, high-performance coils that are not compatible with earlier GPX series detectors.
The 14" Double-D coil in the GPX 6000 can only be used for EMI cancellation or cancellation of conductive soil signals. It is not capable of ferrous discrimination.
The following Minelab coils are currently available to operate with the GPX 6000:
There are currently no aftermarket coils available for the GPX 6000.
The first winding of the coil cable from the coil should always go over the shaft. The coil cable should then be wound closely around the shaft and held in place with the two velcro straps. You should allow enough room for the coil to be able to move freely when detecting.
The GPX 6000 does not track the Ferrite component of the ground. GeoSense-PI uses other techniques to remove the 'X' response that is invisible to the operator.
You do not need a yellow ferrite to ground balance the GPX 6000.
The threshold tone can be toggled on and off in any sensitivity setting with a long press of the Ground Type button.
Note that the Threshold tone is switched on in the Manual sensitivity ranges and is switched off in the Automatic sensitivity ranges. When the GPX 6000 is next turned on, the Threshold tone will return to its default.
The Difficult Ground Type setting is best used in more heavily mineralised soils, particularly with hot rocks or highly variable ground.
The Normal Ground Type setting has the greatest depth on larger nuggets; it is best used wherever possible and always in ground with lower mineralisation levels or less variable ground. Normal ground type may pick up hot rocks as a target. If hot rocks cannot be ground balanced out, you will need to use the Difficult ground type setting.
The GPX 6000 with GeoSense-PI is continually tracking the ground, so either technique would work. Minelab recommends pumping the GPX 6000 up and down above the ground with the Quick-Trak button depressed to achieve the fastest Ground Balance.
Conductive ground does not have to be associated with visible salt. For example, recent rains may make the soil more conductive and increase the unwanted conductive soil response.
Wireless audio is susceptible to audio dropouts when the signal is blocked. Audio dropouts can be reduced by ensuring a direct line of sight between the headphones and the detector. It is best to wear the headphones with the Bluetooth controls closest to the detector. This minimises the path to the Bluetooth transmitter and makes it less likely that the operator's body will block the signal path between the headphones and the detector.
The GPX 6000 will operate for approximately 8 hours when commencing with a fully charged battery. Charging the battery will typically take 5 – 6 hours.
The ML 100 headphones will operate for approximately 24 hours on a fully charged battery and take around 3.5 hours to charge.
The GPX 6000 battery should only be charged from a nominal 12V car battery system when charging from a vehicle.
Minelab currently has no plans to release a replaceable cell or alkaline battery pack.
The USB cable is used to charge the Bluetooth headphones and would be used if a software upgrade were available for the GPX 6000.
Behind the speaker grill is a USB port that can be used if a software upgrade is released. Check the downloads section of the GPX 6000 page on our website for updates.
VANQUISH depth performance is similar but not quite as deep as the EQUINOX. However, EQUINOX detectors are more configurable for varying conditions.
Minelab does not publish the exact frequencies of Multi-IQ technology used in the VANQUISH Series. These frequencies are similar to the Multi-IQ mode in the EQUINOX Series.
The VANQUISH Series detectors only use Multi-IQ (simultaneous multi-frequency) technology.
Target IDs on VANQUISH are the same as the Target IDs on EQUINOX.
Recovery speed varies depending on the mode selected.
Coin mode has the fastest recovery speed so that it can quickly isolate targets from trash.
Relic mode has the slowest recovery speed and achieves the greatest depth. However, it has slightly reduced target separation ability.
Jewellery mode has a medium recovery speed that balances target separation and depth. This makes it a great all-round setting to use.
The Custom mode is programmable. If you program custom mode, it will adopt the recovery speed from the mode you program it to, e.g. coin mode = fast recovery speed, jewellery = medium recovery speed, relic = slow recovery speed.
When the detector is switched off, discrimination patterns in coin, jewellery & relic modes are all reset. Custom mode will keep its saved discrimination pattern.
There are three coils available for VANQUISH. These are:
The VANQUISH Series requires x4 AA batteries and is compatible with both rechargeable and non-rechargeable batteries. The battery level indicator shows the current battery level. Lift the battery cover off the control box to replace the batteries.
The VANQUISH 540 and 540 Pro-Pack come with x4 AA NiMH rechargeable cells and a charger. The VANQUISH 340 and 440 can also operate with rechargeable batteries. Minelab recommends only NiMH rechargeable batteries or non-rechargeable AA alkaline batteries. Batteries rated between 1.2v – 1.5v are acceptable. If the battery has a voltage higher than 1.5v, it can damage the detector.
AA rechargeable NiMH batteries provide a run-time of approximately 11 hours using factory default settings.
Non-rechargeable, high-quality AA alkaline batteries provide a run-time of approximately 10 hours.
No. VANQUISH coils cannot be used on EQUINOX, and EQUINOX coils cannot be used on VANQUISH.
The VANQUISH control box is not submersible. The coils are fully waterproof up to 1 m (3 ft).
The temperature specification for the VANQUISH Series is -10C – 40 C (14F – 104 F). The coil is waterproof to 1 m (3 ft), but the control pod cannot be submerged.
No. Pitch or tone breakpoints cannot be adjusted on the VANQUISH Series.
The VANQUISH 540 has a red backlight for detecting in low light situations. The backlight is 'Off' by default at each start-up to reduce battery consumption.
The Multi-IQ technology used in VANQUISH allows the detector to provide stable and reliable target IDs in light of medium mineralised soils found in beaches or parks. As a result, there is no ground balance function available in the VANQUISH Series.
Multi-IQ technology allows VANQUISH to operate on wet beach sand and salt water with much higher performance than a single frequency VLF detector.
VANQUISH 540 can operate with Bluetooth V4.2 or later and Bluetooth aptX Low Latency headphones. VANQUISH 340 & 440 do not have wireless capability.
Yes. Software updates can be found on the Minelab website on the VANQUISH product page 'downloads' section.
VANQUISH Series detectors are under warranty for three years (36 months) from the Date of Purchase. Detailed product warranty information can be found under SUPPORT at minelab.com.
Including battery weight, the VANQUISH 340 and 440 weigh 1.2 kg (2.6 lbs), whereas VANQUISH 540 weighs 1.3 kg (2.9 lbs), as it includes the larger V12 coil.
VANQUISH 540 Pro-Pack contains the same VANQUISH 540 detector but includes the smaller V8 coil and the ML80 Bluetooth aptX Low Latency wireless headphones.
After turning the detector off, please wait at least 2 s before attempting to restart the detector.
The Iron Bias setting is the same in all modes in all VANQUISH detectors.
Note: VANQUISH 540 has an adjustable Iron Bias that has a similar iron bias response to the EQUINOX.

When XChange 2 is first installed the 'file' icon will not appear until the software recognizes the CTX 3030 being connected for the first time. This is the only time this will happen. After the initial connection the 'FILE' icon will appear and remain. You will no longer need to connect the CTX 3030 to access it.
The factory setting for GeoTrails is off, so you will need to turn it on. First turn GPS ON, then turn GeoTrails ON. From the map screen, press and hold the Map button to access this option. Use the arrows to select ‘View GeoTrails’ and press the Select button.
Enhanced turns on SBAS or Satellite Based Augmentation System which is a generic term for WAAS used in the USA and EGNOS in Europe. These systems use a geostationary satellite to probe the atmosphere and TX this to your GPS receiver. It works well in the USA, but in Europe it seems to be better for planes rather than on the ground. In Australia you get signals from a satellite over Japan which makes your fix worse. Not sure how much of Europe has this as an issue.
The default for the 'User' button is to control the backlight, so if a user changes this to something else, then the backlight is controlled in the Menu/Options/Backlight - ON / OFF / TIME
You’re all done and your time zone has been set.
If you don’t know your UTC Time Zone please refer to the following link: http://www.timeanddate.com/time/map/
In a session, if the WM 10 Wireless Module is enabled and the detector is connected to it then you will hear tones as expected. If you turn off the WM 10 it will 'mute' the detector. Power cycle the detector and you will be able to hear the tones.
The CTX 3030 has a similar ground compensation feature to that on the Explorer SE Pro and E-TRAC models which works very well in most ground conditions, so there is no need to ground balance the CTX 3030 in most conditions. Ground balance should only be performed in 'Extremely Mineralised Ground'. Do not perform ground balance on the beach, this will 'confuse' the detector.
This is a standard feature, when you perform 'Tone ID profile edit', and select Play Tone or Play All, the tones will not sound if the WM 10 Wireless Module is connected.
There are 4 different volume settings. The CTX 3030 remembers what each setting is. If you turn the volume down while using the headphones and then unplug your headphones the external speaker volume will not have changed from your previous setting.
Before placing the twist-lock style armrest on the shaft, turn the lock fully counter clockwise. There is no need to turn the lock completely 90 degrees to lock it. Around 30 to 45 degrees is often sufficient.
This was corrected in a software update. Connect your detector to XChange 2 and check for software updates. We always recommend using the most current software update. If you're on the latest update or the update didn’t correct the problem please contact your regional Minelab Authorised Service Centre.
The modes will change (or be translated) ONLY when changing from ENGLISH to another language and not in reverse. If the detector is initially set up in a language other than English, the modes will appear in that language. But if you change the language to English later, the modes will stay in the original language.
The Trigger will Cancel any adjustment being made and go back one level in the menu.
If you’ve been using the detector a lot since the last time you connected it to XChange 2 then there is a lot of data stored. It could take several minutes for the data to upload. Please be patient.
This could be related to masking, low sensitivity setting, coil overload or etc. Perform a 'Factory Reset' and retest the detector.
To connect the WM 10 Wireless Module to your detector:
If Pairing fails, try selecting another channel
The location of the WM 10 can be an issue for path loss. The human body is very attenuating, so having the WM 10 tucked on your backside away from the detector could cause issues. If you’re having issues place the WM 10 in a clear line of sight to the detector to get best results.
Snapshots are only saved while the detector is on. It is a design feature that the snapshots are deleted when the detector is turned off.
During your initial use of GPS the detector will take a while to build up local data. From a cold start the 'locking in' of where satellites are and etc. takes a few minutes, but it can take an hour to build up lots of local data. This data can be used to get better resolution and shaded sky use.
This is as simple as saving the modes and/or data you want as a file and emailing them the file. Here’s the procedure:
All the modes and other data from your CTX 3030 will be displayed in the list.
The entire FILE Collection will be exported as a single file, and saved in the Downloads folder of your PC. You can then save the file elsewhere or email it to whoever you want.
If you receive a Minelab FILE from someone else simply open XChange 2, select the FILE Collection and then click the ‘Clear the contents of your File collection’ icon.
Then click the ‘Import a Minelab file’ icon.
Then click ‘Choose file’,
and browse for the file location. Highlight the file and click ‘Open’ and the Items within it will be displayed in the File Collection.
Drag and drop the items you want to keep into one of your own Collections or straight into your CTX 3030.
Combined audio produces different tones for highly ferrous objects, and objects with varying levels of conductivity. First you set the ferrous line (horizontal line) where you want ferrous targets to provide the audio response. For example, if you set it at 21, then any target with a ferrous reading of 21 or higher (larger number) will produce the audio tone that you program for ferrous targets. On the other hand, if the target has a ferrous reading that is less than 21, the audio response will be based on its conductive properties. In Combined audio you have four 'bins' representing conductive groups with conductive numbers running from 01 - 50. You simply move the lines to represent different target groups and assign a tone for each group. For example, you could set bin one with the lines at 01 and 14. Any target with a ferrous value less than 21, and a conductive value of 14 or less would fall into this bin and provide the audio tone you associated with it via programming.
Bin two, for example, could represent targets between 15 and 28. Bin three could represent targets from 29 - 40 and bin four could be the remainder of conductive targets with CO values of 41 - 50. With the numbers used in these examples, if you passed over a target with a FE value of 12 and a CO value of 44, it would provide the conductive tone you assigned to conductive bin four. If you passed over a target with an ID of 11 – 22, it would provide the tone assigned to conductive bin two. Again, the user can resize and assign tones to each target group (bin). For those of you who enjoyed hunting in Two Tone Ferrous with the E-TRAC, this takes it one step further allowing you to adjust the FE line, and break down the CO targets into four separate groups.
Gold can ID anywhere in the range of 10-09 to 13-30, and possibly outside of this range. Sometimes the Conductive reading can be very low, like 02, so to improve your chances you really have to dig everything including aluminium foil and pull-tabs.
Regarding settings, the standard Beach mode is quite suitable. One thing you can do is to change the Tone ID profile to Ferrous 35. What this does is it will make low conductive jewellery produce a higher tone than it would in Conductive profile, making it easier to recognize. You can also select Combine, and customize the tones to suit your personal preference.
For saltwater beaches, Manual Sensitivity is recommended, unless your beaches have high levels of magnetic mineralization. If your unit is running nice and stable on Sensitivity 18, try to push it a bit higher. In situations where you are actually detecting in the salt water, turn the Seawater setting on.
The other thing some beach combers often do is to open up the discrimination pattern a little. Mainly dropping the ferrous rejection slightly or simply search in Pattern 2 (simply press and release the Detect button). This is highly recommended on beaches with low levels of junk targets. In this case another thing you can try is changing the Audio Response to LONG. This can improve your ability to hear the very faint target response which jewellery can produce.

No, The FBS 2 coils can only be used on the CTX 3030, while FBS coils can only be used on the E-TRAC, Safari and Explorer Series detectors.
Hardwired coils are more reliable for deep diving detectors.
No, 8 x 1.2V is only 9.6V, and these detectors require 12V to function.
Check to ensure the battery is fully charged. A low battery causes the threshold to get very loud and the response becomes erratic.
Salt, sand and grit will accumulate on the Excalibur II. So make sure you thoroughly rinse it with fresh water after use, including the coil cover, shafts and battery pack. Don't forget the vent holes on each headphone diaphragm as these need to be clear if used for diving purposes to allow for ear equalisation.

You can never predict what level of soil mineralisation will be present in any given location, which is why Normal is the recommended Timing to start with. Then, you can let the detector tell you which Timing to use by sweeping the coil and listening to the stability of the threshold.
After performing an Auto Tune and Ground Balance you should commence searching, and if the detector is too noisy or signals on lots of hot rocks, then the Timing you are using is too aggressive for the ground you are on. You need to select to another Timing closer to the dark end of the below scale, e.g. Enhance.
The GPX 5000 is known to suffer from Electromagnetic Interference (EMI) particularly during stormy weather. There are three known reasons for this interference:
On bad EMI days here are a few tips that can keep your threshold purring:
Ensure you are not using a Monoloop coil with the Coil Rx switch set to Cancel.
Monoloop coils have a perfectly round cable.
Double-D coils have a flatter cable due to the two internal cores.
Put the Coil/Rx switch in Cancel. If you have slightly reduced depth than you’d expect, then your coil is a Double-D. If you have virtually no depth, then you have a Monoloop coil.
The Stabilizer function controls the point at which faint variations in the Threshold begin to be heard. These faint variations can either be ambient noise or faint target signals. As you increase the Stabilizer control, faint target signals will become louder, but the noise level will also increase, which may potentially hide a desirable target signal. The Stabilizer allows you to mask these faint variations to provide a perfectly stable threshold, improving your ability to identify faint target signals.
The Stabilizer is best left in the FP (factory preset) position until the soil conditions in the location are determined. Once the Rx Gain level has been set for the local conditions and other audio settings have been selected, the Stabilizer can then be used to fine tune the Threshold stability.
To find the optimal position of the Stabilizer, ensure that the coil is being swept across the ground. One number below the point at which the threshold begins to chatter, is generally the best setting.
The effect of the Stabilizer could be seen as having a similar effect to that of the Rx Gain control. However, the Stabilizer affects the audio processing only and does not change the Receive (Rx) signal, so should be used as a final stage fine tune. After making any adjustments to the Stabilizer, if the ground conditions change or you wish to change coils, you may need to reset the Rx Gain, but before doing so, return the Stabilizer to the Factory Preset setting first. This will ensure you select the most appropriate Rx Gain level to suit the conditions, and then you can fine tune using the Stabilizer.
Tip: By turning the Stabilizer control close to minimum (anti-clockwise) the threshold will be very stable, but you will have lost a lot of sensitivity to smaller targets. This can be a desirable feature in certain scenarios such as looking for large nuggets in a high-trash area, or using the GPX 5000and GPX 4800 to search for coins or treasure.
Tip: We would recommend the best order for setting these controls are:
The Target Volume controls the strength of target signals, and at settings above 8 it will slightly increase the volume of the threshold as well. This is useful for very windy conditions, for people suffering from hearing loss, or when using external speakers. With the audio amplifier built into the Li-Ion battery pack, you can plug a speaker directly into the battery, and set an appropriate level of amplification using the Target Volume. Be aware that when switching from headphones to an external speaker, you may need to make minor adjustments to your Threshold and Volume Limit controls.
The Target Volume can be used as an Audio boost in quiet conditions, and can also be used to reduce or smooth out ground noise signals in highly mineralised soils. This is a powerful feature, and will work in conjunction with the Stabilizer control, giving you the ultimate in fine tuning ability. A bit of experimenting may be required to find the optimum combination in different conditions.
NOTE: Whenever adjustments to the Gain are required, due to a change of coil or location, make sure the Target Volume is returned to the FP setting first. You can then fine tune to suit the new conditions.
If no targets are detected or buttons pressed for a few minutes, then the unit will start a lost alarm, this will sound long beeping so you can find your pin pointer. After a few minutes the pin pointer will switch itself off to preserve battery life.
This allows you to find the unit if it’s left behind on the ground after digging a hole. The beeping does not occur if it is in vibrate only mode .After 5 minutes of slow beeping the unit will turn itself off.
The battery may be inserted the wrong way if the lid goes on, but it is difficult to tighten. The keyed plastic prevents the battery tabs from touching the contacts - turn the batteries around to fix this.
After turning the Pro-Find on you will hear 2 beeps followed by a shorter third calibration beep. This calibration can sometimes take 15-20 seconds, please wait for this calibration beep to occur before placing the Pro-Find near any metallic objects. If you have the Pro-Find near metal when you switch it will not calibrate and you will need to restart the Pro-Find.
Side detection occurring with the target (or multiple) in the side of the hole. Use the tip of the probe to check around the sides of the hole. Reducing the Sensitivity can also help.
Yes, but be aware that it won’t have the same sensitivity to very small nuggets as a quality Minelab Gold Detector. It will be a good aid in target recovery for larger nuggets.
At maximum Sensitivity the PRO-FIND 35 can detect targets at greater distances which can be both an advantage and a disadvantage. To pinpoint a target sometimes it’s better to have a less sensitive probe to reduce the search area, so we have given you the ability to adjust it how you see fit. The Sensitivity may also need to be reduced in mineralized or salty soils, so that you are only detecting metal and not the ground.
The PRO-FIND 35 is completely waterproof to 3 meters so you can submerge the pin pointer to clean it. Make sure the battery cap has been fully tightened before submerging the pin pointer.
The PRO-FIND 15 is water resistant only. If you cover the speaker vent with your thumb, you can wash it under running water.
Tips for switching on:
Calibration usually takes less than a second when the unit has been used recently
In highly mineralised soils:
Audio on and off (Pro-Find 35 only):
Ferrous tone on and off (Pro-Find 35 only):
The CTX 3030, GPZ 7000 and XChange 2 all use SQLite for their data storage. Using a tool such as SQLiteSpy can help extract the files. There is no need to install SQLiteSpy as the extracted file runs directly.
1. Plug the detector into a PC and navigate to the new removable drive that is created.
2. Open the drive.
3. Inside you will find a file. Copy this to a location to use it. This file is the storage database that needs to be opened.
1. In XChange 2 select the points that you want to extract.
2. Drag them onto the “File” folder.
3. Open the 'file' folder by clicking it.
4. Click on 'export a Minelab file' button.
5. The file should be in your 'Downloads' folder.
6. This downloaded file is zipped, so you will need to use a tool such as 7zip to extract the 'shareData' file inside.
7. Copy 'shareData' to a location to use it. This file is in the storage database that needs to be opened.
SQLiteSpy is used in this example but a similar process with apply to other tools.
1. Open SQLiteSpy
2. Select 'file' > 'Open Database ...'
3. Navigate to the location of the database.
4. Change the file type to 'Any file (*.*)'
5. Select the database and select 'Open'
6. On the left, there are several tables depending on the database file used.
a. "findpoint": this contains each of the FindPoints saved
b. "waypoint": this contains each of the WayPoints saved
c. "point": this contains each of the points used to create a track in all of the GeoHunts. Note that each GeoHunt is identified by a UUID in the "geohunt_fk" column.
d. "geohunt": this contains the UUID that is used in the "points" table to identify each of the GeoHunts.
7. Let's also assume that you want to extract some FindPoints (the same procedure is used for the other points as well).
8. Double click on the “findpoint” table. This will display all of the FindPoints extracted.
9. Click on a row in the table then press the “Ctrl + A” key to select all rows.
10. Press “Ctrl + C” key to copy all data.
11. Open Excel
12. Paste the data into the spreadsheet.
13. In some database files the latitude and longitude need to be divided by 10,000,000 in order get them into the correct format for use.
14. Do what you need to with the points from here.
