I do run my sensitivity high as long as I do not get alot of false signals, and as long as I am not in trashy areas. The GTP1350 does find silver as lon as it is there. Depth is great, I have found targets up to 10 inches. I dig targets on the nickel setting, and one notch above and below, depending on soil conditions I have found alot of nickels ab ove the foil notch. Its a dinger on quarters and dimes. When you get penny signals you might want to dig them so that your not missing small rings, all my silver targets are v ery solid tone. If you swing your coil and get that solid tone both ways dig it, if it only tones one way its usually trash. Pop cans shredded by mowers come up as silver often?
Unfortunately I dont have access to good sites like some of you guys. I have no doubt that I can find silver, maybe not all of it because of depth. I have found several rings in the last two monthes on dry landed, at least half are sterling silver, one gold, one eye ball gold, one silver eye balling lol while out metal detecting.
If it is a strong rough signal, sometimes Ill dig those as well. Good luck, hope this helps, dont be afraid to run that sensitivity hig in areas that arnt trashy!
Never go above 11. Weird stuff happens lol.
