I have a “never been out of the box” AT Max for sale. It comes with an extra WT-1 wireless transmitter...it can be used with most other detectors so that the included wireless Garrett head phones can be used with other detectors. It also comes with a pair of never used DetectorPro Amphibian II headphones. Also included is a never used wireless Garrett carot and never used coil cover. $550.00, firm on the price, shipping included to the lower 48. Best I can figure is that it all adds up to about $935.00. Thanks, Ray Hogan in Waco, TX. Can reach me via email at ecirandr@gmail.com.
