Product Description:
DISCONTINUED - PLEASE SEE THE MINELAB GPX5000 DETECTOR.

The Minelab GPX-4500 gold detector is a proven gold finder with many features and great performance. The GPX4500 gold detector has great performance on all sizes of gold, and penetrates mineralized ground deeper than all basic PI detectors.

Incorporating Minelab’s superior Multi Period Sensing (MPS), Dual Voltage Technology (DVT) and Smart Electronic Timing Alignment (SETA) technologies it penetrates mineralized ground better and deeper than basic PI detectors.

Multi Period Sensing (MPS)

MPS (Multi Period Sensing) is Minelab’s advanced Pulse Induction (PI) technology that transmits pulses of different time periods. MPS also samples the receive signal at multiple time periods allowing target signals and ground signals to be separated. This effectively removes the ground signal from even the most highly mineralised ground while still being sensitive to both small and deep gold. This achieves superior depth in extremely mineralised ground.

Dual Voltage Technology (DVT)

DVT (Dual Voltage Technology) is Minelab’s advanced Pulse Induction technology that uses pulses with two voltage levels to further enhance MPS. The two voltage levels work in combination with the different time period pulses transmitted by MPS to increase the amount of power transmitted into the ground. DVT also allows more of the ground signal to be removed, further increasing detection depth and sensitivity. This achieves ultimate depth in extremely mineralised ground.

GPX-4500 Features:

MPS, DVT & SETA technologies for superior gold detecting performance. 2 coils supplied: 11-inch Double-D for general use AND 12x15-inch Monoloop for deeper detecting 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. Six pre-programmed search modes for easy switch-on-and-go detecting. All six search modes can be modified with your favorite settings and renamed. Stabilizer control for the smoothest threshold. In noisy conditions, turning it up will provide you with a smoother threshold. 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. Backlight with adjustable time-out to preserve battery life. Target Volume allows you to increase the strength of softer target signals. This is 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, and can be used to smooth out ground noise signals in highly mineralized soils. The Iron Reject function allows you to set the desired level of discrimination, from cautious to aggressive. This 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, allowing you to use an external speaker without the need for any external booster.
