About Minelab GPZ19
The GPZ 19 Super-D search 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 (14×13″) search coil. Minelab field testers have spent several months carrying out significant testing so the Engineering team could deliver a superior accessory coil. Larger coils typically detect deeper than smaller coilsof the same configuration. Minelab field test results, in both low and high mineralized 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.
