I have a "used twice" Garrett AT Pro with both sets of headphones and a headphone adapter, original box and manual. Just back from the factory for the shaft conversion upgrade and checkup. Looking to trade for an Minelab Excalibur. My Excalibur needs to go in for service and I need another. The AT Pro doesn't speak Minelab and I don't understand Garrett (and I'm to old to learn) Please PM with any offers.
