Minelab GPZ 19 - 19x18" Super-D Search Coil for GPZ 7000 Metal Detector

The GPZ 19 Super-D coil has been designed by Minelab to maximize the performance of your GPZ 7000 and give a significant depth increase over the standard GPZ 14 coil.
Our field testers have spent several months carrying out significant testing so our Engineering team could deliver a superior accessory coil.

Features

More Ground Coverage
The GPZ 19 coil (19" × 18") has 53% more area than the GPZ 14 coil (14" × 13"). It’s perfect for wide open spaces and covers more ground in less time!

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.

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

Super-D Coil Technology 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.

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.

* When compared to the average performance of the GPZ 7000 detector with GPZ 14 coil in typical environments. Actual performance depends upon prevailing conditions.

Detector Depth & Coil Size Comparison

Detection depth and gold sensitivity depends upon the detector technology, the coil size and the configuration. Increasing the coil size on a GPX Series detector (from Commander 11" to 15"×12" to 18") will give a measurable depth improvement. Increasing the coil size on a GPZ 7000 from GPZ 14 to GPZ 19 will also give a significant improvement.
