GPX 4800

So you want to find a patch

May 01, 2014 10:00am

This blog is about highlighting some of the decisions I make when out patch hunting and why.

Tracking, Motion, and Sweep Speed – Part 2

March 14, 2014 03:04pm

One of the hardest skills for a new detector operator to develop is a slow swing speed, now read how...

Tracking, Motion, and Sweep Speed – Part 1

February 14, 2014 10:27am

With the introduction of the Motion settings on the GPX series detectors, there has been a bit of confusion among some users as to what it actually does, and also how it differs from the Tracking speed selection. I’ll start with explaining Tracking speeds.

The new Minelab PRO-SWING 45 harness

August 02, 2013 10:00am

If you own a GPX 4800, GPX 5000 or the new CTX 3030, you'll be interested in Minelab's new harness; the PRO-SWING 45.

All GPX models are supplied with a good quality harness, and the PRO-SWING 45 builds on this platform, taking it to a higher level.

The main inclusion with this harness is an integrated J-strut, designed to transfer the weight of the detector from your shoulder and neck, down to your hip...

Those little ones add up

February 21, 2013 02:39pm

There’s been a real buzz around the world lately with the discovery of a monster gold nugget in Victoria’s Golden Triangle; it never ceases to amaze me the amount of large nugget finds that keep coming out from the richest, but also the most detected dirt on the planet!

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.

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 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...
