It's a nice unit and works good in the wet sand to the waters edge i got this one for rotting around in the dirt but (just when you think your out the beach pulls you back in) no issues at all .Your machine will tell you how much sensitivity it wants the closer you get to salt water,just drop your sensitivity till the falsing clears up.I run all my units as hot as i can.Take some targets out and bury them in the sand and do your testing thats how i like to do it,iam just not a air tester one other thing ( if in doubt dig it out ) If i can help in any way just give me a holler. Good luck
