Minelab
GPX 4000
Step
up to the next generation in High-End Gold Detection!
Never
before has Minelab offered a more versatile, easy to use, gold prospecting
detector that has more power and performance than ever!
New Features
LCD
Function Display - The most obvious change to the GPX-4000 is the
new LCD display on the rear of the control box. Simply scroll through
the various functions of the detector and select the level required.
All the variable level controls offer precise numeric settings for
more accuracy. Now you can compare the effect of different settings
precisely and easily remember your preferred levels, without the
risk of settings being accidentally changed during transit or while
detecting. All setting changes are saved automatically on Shut Down,
and loaded up when you switch the detector on, then at anytime you
can restore back to the Factory Preset settings.
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
aluminium 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.
