Bought a headphone adapter last week for my AT Pro. Wanted to use earbuds since its getting so hot - will allow me to wear a wide brim hat. Hooked everything up, but still got sound thru the detector speaker and not the earbuds. So took it apart and the plug end of the adapter pulled out, staying in the detector. Pulled it out and came here to the forum for help from the experts! Seems as if I got a bad adapter. Called Garrett, spoke with Adam. Explained my problem. Adam sent me a new adapter, no charge. Didn't need me to send the old one back or even ask for proof of purchase. Got the new one in 2 days! Hooked everything up and working great! Garrett customer service rocks!
