hi everyone i just got an ace 350 and i don't think i like . if anyone can help that would be grate. if i am in coin mode it may sound off and show 25 cents and then its gone never to sound off anymore like a ghost , or i find it and its a small piece of beer can ( small to med ) if i turn the sensitivity down, same thing i may find it may not . this thing went off and showed a penny so i dug and nothen i checked the hole and the pile ( nothen). sometimes when i try to pin point something and cross the target and go up in the air over my head its still sounding off ... maybe it was that 747 at 20 thousand feet (LIL JOKE) this is just a few things its doing it does funny things in every mode. i was hopeing after i got this 350 i was going to save time digging i have a ace freedom pulse that was my grandmothers and its seems to do better. should i have saved up more and got a A.T. pro?? thanks for any help you guys and Gail's can give .. p.s. i am using dubble D coil
