[QUOTE="KarlS, post: 187814, member: 2409"] Although I haven't tried it on the basalt and gold myself, it should work. I do similar ground balancing out unwanted signals when coin shooting. I normally use X Terra 705 for parks detecting, but now and then I will come across a patch littered with hundreds of beer bottle tops. The VLF is total useless in that situation. So I bring SPP along, ground balance beer tops out and cherry pick goldies. Mind you it will still sound on large metal objects, but that is not much of the problem. If GB very carefully it will still detect 50c and 20c , on reduced depth. I prefer to use small DD coil for this. My SPP is one of the first ones that has been modified by me when testing hiccup mods. I also added conductivity switch to it. I think that that by carefully adjusting the GB and the Gain you can eliminate almost any single undesirable signal and still hear signal from the metal you are looking for. Although it may be at reduced depth. Karl [/QUOTE]
