I've had my AT Pro out only twice, the first time on my own property (old 50 acre farm) which I had beat to death with my 2500 for the past full year, and found a civil war stirrup a foot deep. It was in the 20's with a hard wind, so couldn't stay out long. The second time was at an old homeplace in town where I had found a Merc, four wheaties and a few other coins and a ton of nails with the 2500. The AT Pro found me 27 coins which included two Mercs, ten wheaties and several other coins (three of which were eight inches deep under large rusty nails,) an old metal whistle and a silver ring to which my wife claimed immediate ownership. Remember, this was after several goings-over with the 2500. There is a definite learning curve, but when the Pro says COIN, be prepared to dig. I now have to go back to all those nail-infested sites and start over. This is a relic hunter's dream, and ain't too shabby on coins, either. I'm 64 years old and thought the connectors might be a challenge, what with all the negative press, but they were no-brainers, and it's not like you'll have to take them on and off every time you go out. If I had to change anything, it would be for a wider digital range for coins, as aluminum will occasionally fool this and all other detectors. I am a very satisfied user of Garrett products for 43 years, and the AT Pro is the best yet. Jugg.
