Last night I was detecting with Al. It sounded like my detector (E-trac) was cutting in and out, and when it was in, there was a crackeling sound. I unplugged the earphones, and it was working fine, which led me to believe it was the ear phones. I used the inner part of my shirt to wipe off the plug, and blew into the jack to clear dust. This seems to have fixed the problem.
I personally think there is a design flaw to where the jack is on the e-trac. It's in a horrible location for many reasons
I just wanted to give a heads up so if anyone else experiences this, they can try this before giving up and going home...like I almost did
