Waterproof (to 1m/3 ft†)

The GPZ 19 coil is waterproof and submersible to a depth of 1m/3ft. You can easily detect rivers, or detect in rainy or wet conditions.

Improved coil geometry gives less magnetic coupling between transmit and receive windings, resulting in reduced ground noise. Hear less noise and more gold!

A Super-D coil consists of a central transmit winding and two outer receive windings. The GPZ 19 coil has isolated suspension windings that are less prone to mechanical vibration noise.

† GPZ 7000 detector is weatherproof only.

Deeper Detection (average 30%)Larger coils typically detect deeper than smaller coils of the same configuration. Minelab field test results, in both low and high mineralised ground, using a range of natural gold nuggets, give an average 30% detection depth increase when measuring performance of the extra large GPZ 19 coil compared to the standard GPZ 14 coil. With nugget sizes of 10g and below, the GPZ 7000 High Yield Gold Mode gave superior in-ground results. As the selected nugget size increased above 20g, switching into GPZ 7000 General Gold Mode provided an additional depth increase over High Yield.
