CTX 3030 Integrated GPS and Mapping

May 24, 2012 10:37am

You can now see why I haven’t been posting for a while. The team creating the CTX 3030 have put in a big effort to pull together all the features and technologies that make up this detector.

With the exception of my fridge, there is almost nothing that can’t be enhanced by adding GPS. The CTX 3030 has an integrated GPS that can...

CTX 3030 Discrimination Advantages

May 16, 2012 09:37am

We are pleased to bring you the new CTX 3030 metal detector. We have been working on this for quite a while now and it is great to finally be able to talk about it. The detector has a heap of great features, some of which haven’t been seen in a metal detector before. From Engineering, we think that you can do great things with this detector. In this post, I’ll introduce some of the discrimination features that you haven’t seen.

Why Pulse Induction metal detectors work so well for gold detecting

November 22, 2010 11:51am

So as not to make this article enormous, if you see apparently strange new terms or acronyms, please consult our Terminology reference. (http://www.minelab.com/aus/consumer/knowledge-base/terminology)
By now, I would imagine that many metal detector operators have come up against the problem of mineralised ground when looking for gold. This is ground that produces noise from a conventional detector. Many gold fields around the world contain mineralised ground to varying degrees. In Australia, the gold fields contain exceptional levels of mineralisation.

'Recovery Deep' in depth

October 22, 2010 02:23pm

The Recovery Deep setting on the E-TRAC, Explorer and Explorer SE detectors is designed to enhance the detection and identification of deep targets. This article will explain the way in which deep recovery mode enhances the operation of the detector and points out those situations when you may not choose to use this setting.

When Recovery Deep is turned on, it only has an effect on weak signals, stronger signals remain completely unaffected. When Recovery Deep is turned on and a weak signal is detected, the identification signals undergo stronger filtering to smooth out the data

Specific Ground Balance on the GPX detectors

October 13, 2010 01:58pm

The GPX-4000 metal detector first introduced a special ground balance mode called Specific Ground Balance which is still used in newer GPX detectors. This ground balance mode may allow the detector to ground balance in areas that otherwise would have too much ground noise. The Specific mode uses a special second-order ground balance algorithm that can deal with more complicated ground responses than the normal first order ground model.

If you ground balance in the normal way and the detector still displays ground noise then this may be a situation for Specific ground balance mode.

Don't forget Factory Preset!

September 20, 2010 01:50pm

I have heard from some users that have tied themselves into knots when trying to find the best settings for their detector. This can happen because there are some combinations of settings that don’t work well together and there are some lesser used settings that you may have set and then forgotten to check.

In these cases please remember to perform a Factory Preset. This will return your detector to the settings that it contained from the factory.

GPX 5000 Electronics Changes

September 08, 2010 10:30am

By now you have probably seen the GPX 4800 and GPX 5000 brochures and seen the term ‘Improved electronics’. This post will enlarge on this feature a little and demonstrate an effect of the changes that will enhance performance in the field.

GPX Audio Controls

August 16, 2010 10:16am

In this post I will try to explain the GPX audio controls in a different way to that described in the user manual. There are tools available on a web page that can't be used in a printed manual. I'd like to try and visualize the way that the audio controls affect the sound that the operator hears

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...

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...
