I bought a used Explorer II and have been trying to learn it. I used the Learn mode and scanned in a bunch of coins. I went to a trashy site and am getting a lot of high pitched signals that are coming in 21 30 or something like this. I usually only dig 00 30 but my question is should I ignore the first number and go for the sound and second number?
I always say if you spend more than 20 seconds analyzing it, you're wasting your time. You can't rub it into a good target and if it's questionable, you might want to just give it a check with your eyes.
