Thinking of getting a Garrett GTP 1350 . But I have a few questions. I'm told by some that it can't handle much more than "light mineral conditions" any truth to this? Also, some tell me that it's more suited for silver and coins....that it is not "hot" on gold rings and gold jewelry? And finally is it "hot" on low conductivity targets?? How is the unit for extended use (3 to 4 hrs ) . in it's on the rod form?? I 'm worried that it might be front heavy ?? I have noticed some sort of anti-Garrett bias in my area......even though the people telling me not to get a Garrett have never owned one....but some friend did and didn't do well with it. That's why I'm here to get help and honest answers hopefully from people who have used this model A big thanks...... to everyone who cares to help me out on this one!!!
