GPX 4500 The Gold and Precious Metals Detector
GPX 4500 can detect smallest and tiniest gold nuggets underground
but with nearly error-free results in all ground conditions.
GPX 4500 offers the serious prospector a top of the line PI unit at an exceptional price ,
also it is supplied with 2 coil options and 6 pre-programed search modes
to have you out the goldfields quickly and unearthing those precious gold pieces.
– Versatile Timing settings for various ground conditions
The 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 large targets alike.
The Sharp timing is more suited to quieter soils and can also help to pinpoint faint targets.
– 2 Search Coils
1 – 11-inch Double-D
2 – 11-inch Mono for general use
– 6 Search Modes
The device includes six pre-programmed search modes
so for easy switch-on-and-go detecting.
All six search modes can be modified with
your favorite settings and as a result customized .
– Stabilizer control
The stabilizer control for the smoothest threshold in noisy conditions,
turning it up will provide you with a smoother threshold.
But In quiet conditions, decrease the stabilizer and faint target
signals will be more obvious.
– Ground Balance OFF for neutral soils
This is a useful feature for very benign low mineralized or
salt saturated soils.
This setting will also work well for treasure
or relic hunters in loam or sandy soils.
Back light with adjustable time-out to preserve battery life.
– Target Volume Adjustment
Target Volume allows you to increase the strength of softer target signals.
This is also useful in windy conditions, for people suffering from hearing loss,
and to adjust the audio volume when using external speakers.
This can also provide an audio boost in mild soils,
also it can be used to smooth out ground noise signals
in highly mineralized soils.
– Iron Reject
The Iron Reject function allows you to set the desired level of discrimination,
from cautious to aggressive.
As a result it enables detecting in areas with high levels of ferrous junk.
– Built-in amplifier
So you can hear soft target signals from deeper nuggets, more easily.
The Li-lon battery pack includes a built-in audio amplifier also,
allowing you to use an external speaker without the need for any external booster.
