NEW TIMINGS
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.
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.
