I have used a few other brands of detectors and came back to the GTI. My friend and I hit a park last month, he was using a Minelab Sovereign GT and myself the GTI. After 1 1/2 hours of hunting I had a pocket of coins, he had a bag of garbage. He would get a signal and have me go over it. I would tell him I believe it is junk at around 6 inches. He would dig it and recover a pull tab. He was getting very deep targets that when I ran over them with GTI I couldn't get them to show well on the size meter. They were just too deep. When I would run over the object in all metal and let it register I could see on the meter that it was junk. He is old school (which I believe is the best) and dig the object. With a deep hole at close to 12 inches out popped an old beaver tail tab. At the end of the hunt I had almost $7 in change, he had recovered 13 cents. I was just digging objects that were coin size and had notched out nickels because I didn't want to dig pull tabs. This park has lots of can slaw and other junk.
I wish someone would tell us why the size option seems to only work well to 6 inches for coin size objects.
Yes I know that it is just a visual aid, that it is not perfect, and that one can miss good objects. But between two equally good machines I spent a lot less time digging garbage. The only junk I dug was 3 pull tabs and 2 copper fittings. In my opinion that wasn't too bad.
One last thing to add. Remember a machine is only as good as the person that knows what they are doing with it. Without experience and time with it, one won't find much. My friend, just like myself, knows his machine well.
