We have tested new coils for LP ZERO and GM4. As Golden Mask fans may know, the larger Fighter coil was originally developed for heavily mineralized soils. It had the best results in them, but unfortunately in low mineralized ones it was a bit weaker than the basic 30 cm 2D probe.
The Golden Mask brand is one of the stalwarts of the detector market, so when I found out there would be a new model in 2020, it didn't leave me cold. Despite the initial difficulties, the detector came to me and testing could begin. I was most interested in how the detector would be better than the previous version.
