For those AT Pro owners who are looking for the adapter to use headphones other than Garrett's, the adapters are now available. I was on the waiting list and received mine last week. It was easy to install and comes with instructions for several installation options. I like the Rattler headphones and was waiting for the adapter so I can use my favorite headset with this detector. I used it for the first time last week and everything worked fine. Weather permitting I will be out again this weekend with this set-up. Cheers, Mark
