Well, been checking it out in my test area an I am impressed so far. The ground is rock hard here now but it works rather well. I have a .69 cal minnie buried at a measured 10". The GB in disc mode on 0 will not hit it, but in all metal it bangs it hard. Kinda reminds me of the T-2, which was the same way. It does hit hard on brass because I have a Union coat button at 6" that it will nail hard, even with the gain at 50%. I hope for rain for our area this fall, as I think the GB SE will be a killer relic machine in really trashy iron areas in the camps that I have worked to death with other detectors..........
