I have been detecting for a few years with my GMT it has found me some nice pieces but nothing really small I manually ground balance it most of the time. The area I work is loaded with smaller pieces that i know i should be picking up I tried the shooter coil for my GMT but its too erratic the first one I had worked great for about a week then it failed I sent it in and got another replacement which seems to be just as erratic as the previous one ended up no matter what the gain is set at. From my reading it seems to be a common problem some people get lucky and get a good one I didnt so I just gave up on it but the 10" coil have found some decent pickers but I know its not cleaning up the area like I want. Id love to grab me a PI and go deeper in the area but I cant justify myself spending that much for the limited amount of time I get in the area and the short season I have due to work so I just will get a more sensitive detector and pick up the small bits in the area hopefully. Here is some of my Wyoming gold. Its hard to miss a 1.67oz nugget no matter the detector lol But I wouldnt have a problem digging those up all the time. I dont have pictures of my smaller pickers they are in another bottle i use for testing in the field.
