The Minelab GPX-4500 Pulse Induction (PI) gold nugget
detector is a refinement of the highly successful GPX-4500. The GPX-4500
is the ultimate gold finding detector with new added features that makes
it stronger and more versatile than ever before. Incorporating new SETA
technology, it is quieter and more immune to interference, making those
faint targets even easier to hear. No matter if you’ve never picked
up a detector before, the GPX-4500 has automatic functions and pre-set
search modes that make you an expert in a matter of moments. Quieter
operation, louder target signals, improved discrimination, and more
versatile, the GPX-4500 is the gold detector that gives the best results.
Alaska Mining & Diving Supply owner Steve Herschbach
has been tremendously successful with the Minelab SD/GP series detectors.
Steve started out with the Minelab SD 2000 and has used every SD and
GP model made since the SD 2000 was introduced. Now he just got his
new GPX-4500! Steve is by no means sold on any one brand or model of
detector, but when it comes to finding large gold nuggets in highly
mineralized soils he believes a Minelab SD or GP series detector is
simply the best for the job. The worse the ground mineralization and
hot rocks get, the better the SDs and GPs will compare to other detectors.
If you want a detector that will find large gold nuggets deeper than
any other detector, you need look no further than a Minelab pulse induction
detector.

NEW GPX-4500 FEATURES
• NEW TIMINGS so the GPX-4500 is even more versatile.
Users of the GPX-4000 have learned just how valuable it is to have a
range of timings to optimize the performance of the detector. In addition
to the four timings found on the previous model, the GPX-4500 now introduces
two new timings, Enhance & Sharp. The new Enhance timing is a powerful
feature, similar to the Sensitive Smooth timing, but provides an improvement
in the depth and signal response on small and larger targets. The Sharp
timing is more suited to quieter soils and can also be used for pin-pointing.
• NO-FUSS DETECTING WITH PRE-PROGRAMMED SEARCH MODES
The GPX-4500 offers pre-programmed search modes, for easy ‘switch-on
& go’ detecting. In addition to the General and Deep search modes are
four others, Hi Mineral; Hi Trash; Patch and Test A modes. All 6 search
modes can also be modified with your favorite settings and renamed.
• GB (Ground Balance) OFF for neutral soils. When
searching in non-mineralized soils, ground balance can be switched off
to give increased depth. This setting will be popular for treasure and
relic hunters in loam or sandy soils.
• BACKLIGHT so you can read the LCD menu in any light,
day or night. The backlight has adjustable time-out to preserve battery
life.
• STABILIZER for the smoother threshold. The Stabilizer
function is a fine tuner that gives the operator full control over the
threshold stability. After all other functions are set, you will use
the Stabilizer to give fine adjustment for a smoother threshold and
the ability to pick up the faintest of signals.
• TARGET VOLUME ... Target Volume allows you to increase
the strength of softer target signals. This is useful for very windy
conditions; for people suffering from hearing loss; and to adjust the
audio volume when using external speakers. This is a powerful feature,
and will work in conjunction with the Stabilizer control, giving you
the ultimate in fine tuning ability.
• IMPROVED DISCRIMINATION gives you access to the
worst of trashy ground. When detecting in a high-trash area like a mining
site or a campground, the Iron Reject function allows the operator to
set the desired level of discrimination, from cautious to aggressive.
This will assist detecting in areas that have previously been rejected
due to the quantity of Ferrous junk.
• BUILT - IN AMPLIFIER allows you to hear soft target
signals from deeper nuggets, more easily. The newly designed Li-Ion
battery pack now has an audio amplifier built in, which boosts target
signals, if using an external amplifier. The design of the amplifier
and the use of high-quality low noise components ensure the signal response
is clear and crisp, without the added background hum of some boosters.

SETA Explained
The GPX-4500 now offers a total of six Timing options
to suit different detecting conditions. Previous GP series detectors
operated using one universal alignment suitable to all their timings.
With so many different timing options packed into the GPX-4500, it was
no longer possible to rely on a single alignment, and so the Smart Electronic
Timing Alignment or SETA concept was born.
SETA automatically sets a precise alignment for each
Timing option. What this means is that in each timing, noises caused
by magnetic interference will be minimized, the threshold will remain
more stable, and signals from highly magnetic rocks will be significantly
reduced. This allows you to harness all the power of the GPX-4500, and
operate it more efficiently under different conditions.
SETA technology allows each timing to operate independently
and much more efficiently so that deep and small hard to hear nuggets
become more obvious.
