I purchased my dfx about six months ago and have been trying to learn it I also got digging deeper with the dfx book . Although complex for my brain I'm slowly learning it but find a lot of things confusing- to say the least ! I've found some nice stuff with it but I can see why some get frustrated as it can be aggravating if it's not set correctly. Anyway I'm looking for someone to ask a few questions I have been reading the book and went to my property that I'm detecting and tried to get the grounds vdi # which was around -91.5 (-88 to -93) but most reading was -91.4 then I tried to find out the ground mineralization strength and I think I did it correctly and those numbers were -90.4,-90.7,-91.2 depth 9.5-10.5 one reading 8.5. Am I correct in using 3 kHz ? If I'm looking for silver coins or would 15 kHz be better or both frequencies? Also with those numbers are there any other settings I should adjust I read sweep speed 1 ground filter 3 any help would be appreciated also do those readings mean it's low mineralization and if so that should be a good thing ?
