GPX-4000 -
THIS MODEL NO LONGER AVAILABLE!
Never before has Minelab offered a more
versatile, easy to use, gold prospecting detector, that
has more power and performance than ever!
A new, advanced digital
control system provides a lot more operator control and
functionality to allow the GPX-4000 to be fine-tuned
for all types of searching. Pre-programmed search modes
optimize the detector at a flick of a switch for different
situations, whether general searching, patch finding or
carefully chaining an area. Access to a number of new variable
functions allows the operator to select their own combination
of settings to gain the best possible performance.
GPX-4000 front panel and battery
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.
Gone is the old inaccuracy of turning the control to ‘about
2-o’clock’ - 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 back on, then at any time you can also
restore back to the Factory Preset settings.
Improved Control Panel Layout
The functions that are
commonly used and switched while detecting are located on
the front control panel for quick and simple adjustment.
Pre-Set Search Modes – Patch Finding, General &
Deep
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 Improvements & Features include :
Never before
has an operator had this much control over exactly how their
detector worked. In addition to the new Search Modes, there
is now greater control over the performance of your detector.
Gain -
The Gain function sets the overall sensitivity 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. Depth on larger targets
is sacrificed slightly, so 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 specially 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
in 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 Hi/Low target signal you are used
to listen for.
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.
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 that you have it on.
Coils
All Minelab SD/GP
coils, Commander, Coiltek and Nuggetfinder coils are compatible.
Power cables, batteries,
regulated power supplies
GPX-4000 5 pin male power
cable
The GPX-4000
uses a new Ion Lithium battery system that requires different
connectors to previous SD/GP detectors. Due to different
working voltages, the older power cables, batteries and
third party regulators are not compatible
with the GPX-4000. Take great care with power cable
connectors as they are easily damaged when getting the detecting
gear in and out of the vehicle.
I found the GPX-4000
easy to use, specially I liked the LCD display that makes
adjusting the unit very simple. It is good to see a dedicated
on/off switch and separate threshold control again. Performance
wise I found that the unit functioned very smoothly over
a variety of ground conditions encountered in Nth Queensland.
The control box is also lighter than before (170 grams lighter).
The GPX-4000 is able to extract more performance
from both the standard 11" DD coils and Mono coils. I expect
that many impressive performance claims will emerge as time
goes by.
