Fighter coil testing - low mineralisation

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.

But that is no longer the case. After about a year of testing at GM, there is a newly modified 13x11 and a brand new 9.5". Tests in heavily mineralized soils were done some time ago and we will definitely do some more. It was clear the Fighter would be better there, but we needed to see how they would perform on the slightly mineralized ones.

The results are tabulated here, the detector was set to just about the maximum possible. Sensitivity to 9 and discrimination to top 2. Thus there is basically nothing more to add. But we wanted to see what we could squeeze out of the coil.

Although we have already done the tests in mineralization and tried some ourselves, we would still like to bring a comparison in heavily mineralized soils by the end of next week. But from what we could try, there is an increase of up to 15% for some targets. In extreme cases, even better identification of small coloured targets in areas of high iron oxide. Of course, testing in such locations carries with it a number of pitfalls, most notably the minor decaypieces of iron can strongly influence the results and sometimes it is almost impossible to get them all out of the soil before testing. So the results there will only be a rough sketch and it is possible that you will do better at state sites.
