GPX-4500
No matter if you've never picked up a detector before, the GPX-4500 has automatic functions and preset search modes that make you an expert in a matter of moments. Quieter threshold, louder target signals, improved discrimination, and more versatile, the GPX-4500 is the gold detector that gives the best results.
~New GPX-4500 Features~
New Timings so the GPX-4500 is even more versatile. Users of the GPX-4500 have learnt just how valuable it is to have a range of timings available, to optimise the performance of the detector in various conditions. The GPX-4500 introduces two new timings, Enhance & Sharp, in addition to the four found on the previous model. 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 large targets alike.
The Sharp timing is more suited to the quieter soils and provides the most powerful detection field of all the Soil/Timing options. The Sharp timing can also be used as an aid to pin-pointing faint signals. Increase in Audio Gain. The design of the amplifier and the use of the high-quality low noise components ensure the signal response is clear and crisp, without the added background hum of some boosters.
~New Functions~
GB OFF~ for neutral soils. In addition to Normal and Specific ground balance options, a third option is now available. 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 saltsaturated soils. This setting will also work well for treasure or relic hunters in loam or sandy soils.
Back light~So you can read the LCD menu in any light, day or night. The backlight ahs 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 treshold 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. Turning it down will provide you with a smoother threshold, improving your ability to pick up the faintest of signals.
Target Volume~ 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 Jewelery 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.
