I got my at pro today went out in the yard for about 45 min.boy it is differant than my tesoro I had a little trouble pinpointing for some reason but I have never used a coil that size either.I will be going to the beach tomorrow I will see if it will work in the surf and wet sand using the manual GB. will post results tomorrow night.It did seme to have a lot of chatter but the yard has a lot of crap in the ground so it was sounding off.I did fine a few clad coins at 4 to5 in.
