I don't beach hunt very often even though I live across the street from a nice beach but we had some super low tides today so I hit the beach today with my Mr. Bills modified IDX Pro. I hunted around and under a local fishing/swimming dock using the little 5.3 Bullseye coil because this site is loaded with iron. The little Bullseye coil did well for it's size. Our beaches her in Washington State are pretty nasty with hot rocks and black sand so ground balancing was a bit tricky but I was hitting coins down to 8 inches.
