Why don't you use the Mode switch on your GPX?

July 09, 2010 01:25pm

In my travels, talking to Minelab GPX users I have encountered few people who make much use of the mode switch. When we first designed the GPX-4000, after much discussion we put a 'Mode' switch on the front panel. Our intent with this switch was to try and let operators do one of three things with this new switch.

1. New users could easily change the character of the detector before learning the finer points of the settings in the menus on the LCD. This is a bit like using the dial on the top of your digital camera to change between Sports, Portrait and Night modes...

X-TERRA 705 Gold Pack - A simple Solution!

July 01, 2010 11:05am

With the announcement of the X-TERRA 705 Gold Pack hitting the street and forums everywhere I thought I would toss out some results from testing for anyone that has not heard me ranting on about how great the X-TERRA 705 really is. The X-TERRA 705 Gold Pack was a simple idea and solution; really there was no need to reinvent the wheel on this one. Take a worldly proven metal detector add the perfect coil for prospecting and offer it at a good price and we answered one of the most asked questions I receive from nugget hunters...

E-TRAC Pin Point mode choices

June 24, 2010 12:32pm

Hello, today I’m going to present a great, ADVANCED feature to be found in your E-TRAC metal detector!
Did you know that the E-TRAC has two Pin Point Modes?
They are NORMAL and SIZING. They both do the same thing but in slightly different ways…let me explain!
The two modes are selected via the Preferences Menu and the Default Mode is Normal.
In Normal the E-TRAC operates just the same as any other VCO type pin point system giving a precise audible location and rising to a crescendo screech when the center of the coil or best detection area is directly over the center of the target – this also ensures correct and ‘true value’ target ID’s
The first sweeps over a target will give a wide response...

The Sovereign GT - a modern Day Classic

June 15, 2010 10:10am

The Sovereign GT's effective, powerful and simplistic design has created a dedicated fan base of relic, coin and beach hunters around the world, and I’m proud to say I’m one of them!

Back in 1989, the first Multi-Frequency detector hit the market, and it set the coin/relic/jewellery detecting market alight – it was the Minelab Sovereign. The Sovereign featured BBS technology (Broad Band Spectrum) transmitting 17 frequencies from 1.5 – 25.5 kHz, to provide maximum depth and sensitivity to a range of target conductivities. The other advantage of BBS was (and still is)...

Four Tips to Help Your Detector Auto Tune or Noise Cancel

June 09, 2010 11:46am

Metal detectors are sensitive instruments designed to detect small changes in magnetic field. Nearby metal changes the field as intended but so do far off thunderstorms, electric motors, electric fences, RF transmitters, power lines and nearly everything that a modern society plugs into an electrical outlet.
Many of Minelab’s metal detectors have a function that allows them to locate and avoid these interfering signals. In some detectors we use the term ‘Noise Cancel’ while in others we use the term ‘Tune’, ‘Auto Tune’ or ‘Manual Tune’. These terms all refer to the same thing, that is the process where the metal detector or the operator searches through the available tuning range, looking for the quietest point at which to operate...

Make the ground disappear

June 04, 2010 09:16am

One of the most frequently asked prospecting questions I hear concerns ground balancing gold prospecting metal detectors; what it actually does, how does it work and is it complicated to perform. I try to share everything with the K.I.S.S. (Keeping It Surprisingly Simple) principle in mind.

When we are detecting there are only a few things we are actually doing one is putting the right amount of signal into the ground (another blog topic) and making the ground disappear.

Think of your ground balance (GB) as the magician that waves a cloak over a box of dirt...

Reasons to use a Small Coil

May 24, 2010 10:51am

Small coils have extremely good depth and sensitivity despite what popular belief would tell you. If you regularly search areas that you know contain valuable old coins and lots of iron and rubbish then you owe it to yourself to get a small coil.

Why should I do that? The reason is simple really...

Counterfeit Minelab Metal Detectors

May 17, 2010 09:30am

Imitation is said to be the greatest form of flattery. However, counterfeit Minelab gold prospecting metal detectors and accessories that don’t work is another story altogether.

Counterfeit Minelab metal detectors and accessories are entering the market which either don’t work at all or have extremely poor performance. Unsuspecting detectorists are being tricked into buying metal detectors that look like a GPX-4500, but at best perform like a $50 toy detector.

We first heard reports of counterfeit GPX-4500 metal detectors late last year and obtained a confiscated counterfeit GPX-4500 from Dubai’s Customs Department. We disassembled it and...

GPX-4500 - Why so many Timings?

May 10, 2010 08:55am

To an answer the question above, one needs to know what the Timings actually do. In simple terms, the Timings control the internal parameters of the metal detector’s electronics, or more precisely, the pattern of the pulses. This pattern defines the metal detector’s performance characteristics. So why not just make a single Timings setting that is good for all scenarios?? Well, yes this is possible, but it would have to be a compromise.

Think of a car transmission, 1st gear is great for a steep hill climb, but you wouldn’t use it on the open highway. Likewise, 4th gear is great for the open highway, but you wouldn’t use it to take off! Timings are the same – each Timing is good at a specific task...

Minelab E-TRAC Audio Tones

May 04, 2010 10:21am

Hi, my name is Philip and I work in R&D at Minelab in Adelaide, Australia. This means that I have probably helped to test or implement some of the features in the metal detector that you are currently using. I’m sure that you love, hate or are completely indifferent to these. In this forum I would like to talk about some of my experiences in creating these features or my perspective on the feedback that I hear from customers. This is my chance to talk with the world of metal detecting rather than those few that I get to meet personally. Please join in and leave a topical comment or ask a question.

My first topic will be on the E-TRAC audio for new users...
