Greetings all from Alabama, I just purchased a Garrett GTI 1500 last week. I have little metal detecting experience. I owned a White's 3000/D when I was like 12 years old. It's amazing how much technology has changed since then. This machine is a little more difficult to master than I initially realized. I'm spending time with it in my yard and in my prepared test bed. It seems to be a little off on some targets giving false id's. I guess I need to play with the sensitivity a little. I realize now that I will have to spend more time with it to learn this machine more. I'm sure I will be asking questions down the road. By the way, I'm new to this forum. David
