The GPZ 19 Super-D coil has been designed by Minelab to maximise the performance of your GPZ 7000 and give a significant depth increase over the standard GPZ 14 coil.
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.
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.
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.
Improved coil geometry gives less magnetic coupling between transmit and receive windings, resulting in reduced ground noise. Hear less noise and more gold.
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.
