I've had my V3 for 2 months and have had fairly good results at inland locations. This time of the year I like to hunt the fresh water beaches in my area. I've been to the these beaches 5 or 6 times with the V3 and have just not been able to get it to work properly. Today, I was determined to work through the problem. I took the V3 and my 4 coils (10"dd, Super 12, 9.5" and 5.3" (all V rated)) with me. In pinpoint mode I could hit a quarter with good depth but in Discrim mode I could not get more than 2" regardless of the coil or program used. There is no EMI in the beach area. I could pick up the quarter on top of the ground fine but if I pushed it down into the sand with my thumb I would lose it by 3". Just before losing the signal the VDI's for the quarter would go to the -90's. I tried a couple of different locations to do the tests. I ground balanced numerous times over the area I was using to do the test. I tried changing filters which didn't help. This is pretty frustrating. Does anyone have any suggestions? Thanks
