are the Garrett AT PROs really that bad? my GTI 2500 had some programming problems when I first purchased it, after the repair it did work like a champ, then on the beach I thought I was getting false hits but after using my trusty rare earth magnet I found the source of all my false signals small pieces of rusty iron picked up by my magnet,with the 2500 in the coin mode the GTI should have ignored those small targets but then again none of my other detectors ignore rusty iron, my 2500 never stops amazing me at the extremely small targets it finds, and small pieces of placer gold that my Minelab Eureka gold missed no matter what setting it was in.But Garrett does have some quality control problems at there plant, I have read numerous complaints about there products having the same prob time after time!
