I have an AT-Pro for sale and I just got it back from Garrett with the upgrades and a new 2 year warranty. I have used the machine very little, it is on it's second set of batteries. It works fine, no falsing. I have the Garrett gizmo installed for extra length on the arm. I am 6' 4" and needed the Gizmo even after the upgrades. I cut the cord to the factory headphones and built my own headphone adapter. You can have the headphones with the cut cord and the original rod that came on it. $425.00 will get it shipped to your door, double boxed. paypal ok. Thanks Randy
