Since about 1996 I have used a Explorer XS then upgraded to the Explorer II and finally the E-Trac. I was able on all three too adjust the tone on silver coins to a high pitch that sounded like a old type bicycle handle bar bell. Can the same adjustment be done on the 3030 ? And when you say waterproof unit, can it take a side-swipe from a ocean wave ? thanks in advance.....
