  Minelab GPX-4500 Ultimate Gold / Metal Detector
Minelab GPX-4500, A creation worth its weight in Gold!
Minelab GPX 4500 metal detector is the ultimate gold prospecting detector with the new added features that makes it stronger and more versatile than ever before. Incorporating new SETA gold nuggett hunting technology, it is quieter and more immune to interference, so that it is a real pleasure to use. 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 prospecting expert in a matters of moments. Quieter threshold, louder target signals, improved discrimination, and more versatile, the GPX-4500 is the gold detector that gives the best results.
Ground Balance OFF for neutral soils.
In addition to Normal and Specific ground balance options, a third option is now available in the minelab gpx 4500 detector. In GB Off the ground balance circuit is by-passed to give extra deep detection. This is a useful feature in very benign low mineralised, or salt saturated soils. This setting will also work well for treasure or relic hunters in loam or sandy soils.

BACKLIGHT, Lets you read the minelab gpx 4500 metal detector LCD menu in any light, day or night. The backlight has adjustable time-out to preserve battery life

STABILIZER for the smoothers threshold. The stabilizer function is a fine tuner that gives the operator full control over the threshold stability. It is tied in with the audio processing circuit, so should be used in conjunction with the four Audio Type options. In quiet conditions, increase the Stabilizer control and faint target signals will be more obvious. Turing it down will provide you with a smoother threshold, improving your ability to pick up the faintest of signals.

In addition to the Volume Limit control, which prevents signals from being too loud, the new 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. The Target Volume can also be used as an audio boost in mild soils, and can be used to reduce or smooth out ground noise signals in highly mineralised soils. This is a powerful feature, and will work in conjunction with the Stabilizer control, giving you the ultimate in fine tuning ability.

IMPROVED DISCRIMINATION that 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 combined with the specially programmed Hi Trash search mode makes areas of extreme junk well worth a search. Also great for the specialist Relic and Jewellery hunter who demands the best, and wants to recover the smallest and deepest targets invisible to most treasure detectors.

BUILT-IN AMPLIFIER so you can hear soft target signals from deeper nuggets, more easily.The newly designed Li-lon battery pack now has an audio amplifier built in, allowing you to use an external speaker, without the need for any external booster. Its uses smart circuitry, which automatically senses a correctly wired speaker, and applies an increase in Audio Gain. 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.
