Pre-Set Search Modes - Patch Finding,
General & Deep Detecting - Different search
techniques require different settings on your
detector to give maximum performance for best
results. If out patch finding over virgin ground
your priority is to cover more ground at a faster
sweep speed, you need a detector with fast target
response, sharp clear
signal and possibly fast ground tracking. However,
carefully chaining an area that has already produced
nuggets requires an entirely different set of
settings. The GPX-4000 offers three pre-programmed
search modes already set up for the three common
search techniques - Patch finding; General detecting
and Deep slow careful detecting. As you get more
familiar with all the new functions of the GPX-4000,
you can then program your own preferred settings for
each technique, or search mode. |
New Functions
| Gain - The Gain function sets the overall performance level of your detector. In areas where the search conditions are mild, you can increase the Gain, and in areas that are more difficult it can be reduced. You'll find using the Gain control in combination with other controls like Timings, Audio and Ground Balance will enhance performance to the ultimate. | |
| Sensitive / Smooth Timing - The GPX-4000 now has two sensitive options. The all-new Smooth option dramatically reduces signals from hot rocks and false ground noises, yet remains highly responsive to small targets. In mild ground conditions, the Sensitive Timing found on previous GP detectors, now called Extra, is the preferred option as it will provide greater depth. | |
| Ground Balance Type - In addition to the normal ground balance that we are all familiar with, the GPX-4000 now has an optional "Specific" ground balance, designed specifically for use in very hot ground and especially useful with Mono-loop coils. | |
| Response - We are all familiar with the standard distinctive target signal we get from small nuggets, it tends to start with a rising tone and then drops to a lower tone. Because we usually find more small nuggets than large ones, this target signal is very familiar to us. The response function allows you to invert the normal target response so that when you're detecting deep ground for large nuggets, the target response from a big nugget is easier to hear, as it will be the familiar target signal you're used to hearing. | |
| Motion - Different sweep speeds demand different software so that the detector can give the best results. The Motion function allows the operator to indicate their intended sweep speed to provide the best threshold stability and target response for that sweep speed. | |
| Volume Limit - Improvements have been made to allow potentially loud signals to be reduced without any loss of signal strength on weak soft signals, even on very low settings. |
New Lithium Ion Battery
For a mere 870g, Minelab's new lightweight Lithium-Ion Batteries hold their charge at almost full power for hours more than conventional batteries and will operate the GPX-4000 for over 12 hours. The intelligent charging system is self-contained in the robust yet lightweight aluminum housing, offering very rapid recharge times of 3 to 4 hours, from either the 12v vehicle or Mains adaptor. Best of all, the available power of the battery can be tested at any time through the LCD display on the detector.
New
Padded Comforter Belt
Included with the GPX-4000 is a new padded waist belt that makes wearing the battery harness all the more comfortable, you won't notice you have it on.

making it one of the world's most sophisticated and powerful

you to customize your detector, making hard to hear sounds,
clear and defined. The discrimination function rejects
strong signals from ferrous junk, allowing more time
detecting and less time digging unwanted targets.

SD 2100v2, however uses Minelab's exclusive technology known
as MPS or Multi Period Sensing. This enables the SD 2100v2
to minimize the effects of mineralization, to penetrate

This effectively has overcome the problem of ground noise,
and it essentially only produces a signal on actual metal
targets such as a gold nugget.
