I'm kinda curious about what the limit is for small gold with the GTP & various coils. For example, the MXT can get down to roughly a grain in all metal & running at full boost. Some of that capability is due to post processing in the DSP (it has one too). I'm wondering if the GTP also does something along those lines. It also has relevance re. beach hunting and diamond earring studs. I suppose this also applies to the GTI 1500. ..Willy.
