• 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 .
• 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.
• 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.
