This question is to all you seasoned explorer ll guy's . I've been running with my audio on normal since I got my detector may of 05 . This detector rock's . I've done good in normal and dig lot's of deep targets that are nothing more then a tick .I've try ed to run audio one in some of the trashy areas I hit I cant stand it . I have a friend who runs his explorer in audio one and dose awesome . I feel I do good but I want to get all I can out of my explorer . Can someone tell me the advantage of running in audio one .
