AT Pro - am I doing it wrong?

I had similar results when I started, doing it the way you're doing it. What works for me is Pro Custom, Iron mask set to 40, and manual ground balance regularly. It is "noisier" this way, but honing in on good targets and getting a two way signal becomes regular and you'll start digging more good targets.

Thank you sir. I realize I have a LOT to learn.

I would run Pro Coin or Zero, audio off, disc to like 22....Then try it, if your swinging and hear a good tone, slowwwwww dowwwnnn and do 2" (or so) wide swing over that tone, does it repeat? Urn audio on, still nice tone?, turn 90 degrees, tone good? Dig

If there is junk, depending on what it is, it can give what seems like good tone, then disappear....If you listen real close (Or get time on the ATP) you will hear that it really is not a clear or perfect good tone, edges of tone will be rough....

Try this, get a penny, qtr, dime and couple nails (Rusty best) and lay the coins (no nails) out a foot apart, listen to the tones, in STD you get the bell sound vs Pro it is diff (More info to learn in Pro Mode)...hear the crisp tones? now lay nails on either side of a coin swing over it, hear the tones? also try diff speeds of swing, diff spacing between nails, hear the difference?
