I work saltwater beaches in autotune; for a wider scan?. Believe it or not, I keep the volume at 10 and wear earplugs so I don't go deaf <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt="
">(a tip from the Golden Olde site I tried) The faint tones are really boosted at that point and I can still hear them with the earplugs in while the REALLY loud tones are lessened. I've dug up some things I'm sure I would have missed because I don't think I would have heard them... but that's me.
I adjust the sensitivity to where I can bearly hear a hum. I don't really have a problem with mineralization so ground balancing is not a problem for me.
When I hit a target in autotune, I simply flip the disc knob to "0" to ID it. I very rarely use the pinpoint as I find it pretty easy to target in autotune. I'll "X" out the target, walk around it, or raise the coil a little to narrow down the area.
If you're having a problem with pinpointing, definitely move off the target, repress the button and go back over the target area. It works.
Hey, if you have doubts about how your machine is set up / reading, just bury some coins at varying depths. Kinda like a test garden only in the field... Just make sure the area is "clean" first <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt="
