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.
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.
Deeper Detection
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.
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.
Waterproof
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.
