Hi Robert, I have used the GTP1350 somewhat and hunt in all-metal with it. Personally I love the feel and balance of this machine. With the Graphic Target Profiling mode on this machine and others too Mr. Garrett must feel that it is a viable feature and has made it a large part of these machines. GTP mode requires a specific method to be reasonably accurate. When going to this mode to size up a target you must maintain a steady sweep speed and sweep width. I believe this is critical to get the GTP to help you at all. I would want to think that maybe it would shine a little better in relic hunting. I personally don't use this mode at all because I have not found it to be a great advantage in coinshooting. Maybe I am the one that is not getting it right. So I will let you make your judgement of this GTP mode from your experiences Robert. But when you purchase one of the GTP type machines you are paying extra for this capability to be sure. But if I were you I would give it as much time needed to see if it is an advantage for you Robert. So I will leave this with you and I wish you good luck with the 1500 and again I like the GTP1350 and I have just ordered the 4.5" Crossfire coils to try on it. God Bless Robert and if I can help you more let me know.
