Fighter coil testing - low mineralisation

Categories: Golden Mask - Reviews and tests , Golden Mask GM4 metal detector , LP ZERO metal detector

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.

  Part of the buckle 1 Kr. Fer II 2h RU 1 CZK  
9,5" Fighter 40 cm 22 cm 25 cm 29 cm  
13x11" Fighter 46 cm 24 cm 28 cm 32 cm  
17 cm 2D 34 cm 19 cm 22 cm 25 cm  
23 cm 2D 38 cm 19 cm 24 cm 28 cm  
30cm 2D 44 cm 24 cm 27 cm 32 cm  

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.

hm, já mám fajtra od vánoc a na písku dobrý, ale na čediči je to nepoužitelný,... Odlaďuju ale prostě se to nedá... Asi něco dělám špatně. Jo a na otřesy je jednou tak citlivá než pův. spider.... Což je za mě další minus dolů,. Hned jak to půjde, tak zase přezbrojím na původní model,. Ale třeba je to jen mnou. o:-) :-D

Jak hodnotíte GM 6 s civkou 13x11 fighter, dá se mluvit o tom, že se přiblíží na Noxe 600,nebo MD Gauss. Děkuji.

To Peters: ono je otázka, co na tom čediči opravdu za něco stojí, pokud je ho opravdu hodně. To skutečně není místo pro VLF detektory.
Alois: Ne a ne. GM4 a nebo i Zero jsou jinde.
