I was going to ask specifically where you were hunting ?
I can tell you that even with a GREAT machine the wet sand can be devoid of targets..
Up in the dry sand as well but there is more trash up there...
Also
ALWAYS take along some pocket change, (include nickels because they read different) if your not getting any signals drop that shit in front of your coil to make sure your machine is functioning..
It does happen believe it or not..
Things to try
1. Find a Pier and try around that, it attracts a lot of attention,
2. Find a Public Parking area that doesn't charge or minimal charge for parking,
3. Anyplace that has close to beach side restaurants and amusements
4. Avoid areas that appear to have HIGH concentrations of Condos or Rental properties but otherwise no business properties because for some reason these places always seem bare to me, even if they are full of people..
If your walking in the WET sand and your machine seems to make a lot of noise, (Some single frequencies do some don't) turn the discrimination up until it's quiet, as the reaction is only on the very low conductivity scale.
If walking in the DRY sand, shoot for the area that is just above the HIGH TIDE line as this is the line where most people love to sit...
Good luck and let us know what happens..
