I have been using my spectrum xlt for a couple years now and go out quite often, Parks, and Beach, I have found a ton of coin and jewelry and a few I could call treasures. I mostly use the programs on the unit. I have tried several adjustments however I am yet to find anything deeper then a few inches and or gold rings or any gold. The one beach I hunt I have found all types of silver nothing deeper then 3 inches. I know there is gold here. I run into a guy one day who had lost his gold band wedding he had bought a cheap model and he had a general area where he lost it the day before but I will be darned if we could find it. My question would be ? Why I have a standard 9 inch coil , would I be better off going with different coil? different MD or dose some one have a program setup? I buried a dime at 4 inches and I will be darned if any of the programs would pick it up. In fact for me to relocate it I had to remove about 2 inches of cover. I am thinking a MXT what is your thoughts
