Ive been using the 1350 for about 3 months now. I can say it takes some geeting use too. I do not use the profilling mode unlees im figuring out the size of the target , after I pinpoint it. detectors never lie at least not mine. never dug somthing up that the detector didint say was there. roots do seam to make mine beep somtimes, I dont no why. Pinpointing is pretty good. mine is usally an inch or so up and to the right of the id spot. never dismiss any beeps. I come to find out that any coin beep is most of the time a coin. even if its faint. certainly if the coin is on its edge. ive dug them up to at least 7 inches. this is a verry good machine. go slow,it pays off in the long run, I promise. Practice, practice, practice. is all I can say. Im still learning mine myself. hope this will help you enjoy ur machine as much as I do. good luck and happy hunting. see you in the field.
