I have metal detected Ocean City Maryland with my AT Pro for over 10 hours total now. My STAVR Scoop Evro Excavator was an excellent choice. I am able to get little chatter in the surf but it's tough when the surf isn't really calm and I didn't do it much at all. In dry sand, quarters, dimes and pennies are easy to detect. Nickels hit where pulltabs do and I have avoided some hits around 53 figuring I'd pass the chance of a nickel to avoid effort on junk. Idiot me! I figured gold bands hit like mine-67. But I just found out my wife's band hits at 53 and diamond ring 49 (I was digging high 40's but not 53). Live and learn! Question: are gold bands and rings so heavy they sink to below detection depth after a short while in DRY beach sand? I'm sure they are detectable for a few days at least but do they quickly sink? I did find one ring but it looks like junk. I also found about $10 worth of change overall. One other observation is sometimes I get a hit that indicates a coin that I miss on the first scoop, and it doesn't ping clearly with a number after that. When I stick with it, I do find the target even if it's an inconsistent faint beep for a while. Also, coins might jump a little on the reading (i.e. 81 to 84) but bottlecaps and cans jump 20 or more on the scale.
