I've been monitoring this site for quite a while, but didn't feel like I could contribute anything worthwhile. I've used Garrett detectors almost exclusively since 1969 and have used many different Garretts, beginning with the Master Hunter BFO, and finally decided to try some of the newer Garrett technology. About a year ago I bought an Ace 250, and have really enjoyed it, then for Christmas I bought a GTI 2500. My problem lies in trying to pinpoint with the newer detectors. I've been detecting around a 115 year-old house with the 2500 and have found silver quarters and an 1896 Indian head penny, lots of wheaties, pocket knives and a horseshoe, along with assorted other coins and junk. Whenever the target is difficult to pinpoint, I get out my old ADS 7 and find it right away. I've replayed the video several times, practiced on clean ground and made all sorts of adjustments on sensitivity, etc., but obviously I'm not doing something right with the 2500. I would appreciate any pointers you experts could share. By the way, I just ordered a Pro Pointer. Thanks. Jugg.
