I'm sympathetic to all who've had problems with the AT Pro. The land problems were fixed starting with March production & Garrett can tell you by serial number if you have the improved version for land. I have post-February model so OK for land?
I'm thinking the improved leakage protection units just started with those that have the camlocks? So I may need to send mine in for that. If I wait until Dec 26 or 27th to send it in, I can get 1/2 year added to warranty if not too late.
Model was rushed to market, a gamble but detectorists wanting something new & not wanting to wait. Garrett had no recently designed detector above Ace series. The older units had arm rests not shaped like arms, maybe too big & heavy, but good IDs.
I got a 7" deep dime within first 5 hours of use, STD mode, sens 7 of 8, high disc. 7" is the deepest dime I've found with correct visual ID, most do 3"-5" with correct ID. And with this soil being mineralized 7" ties my all-time record depth since 1976. But find Pro mode not as much to my liking, me or detector problem, don't know.
The only other current detectors I'm aware of that retail for under $900 that might have correct ID at depth are Fisher Gold Bug DP & Teknetics G2, but they can't be submerged. And AT Pro outdoes them in air tests. Despite all their repair costs, I'm guessing Garrett will not raise the price on the AT Pro camlocks edition, making it the best overall detector under $900. Keep trying & report successes! HH, George (MN)
