well - I had a few spots that at low tide on my toes - using snorkel and mask _ I worked parallel to the shore and
got 3 old gold in one straight line about 10 ft apart - I was in in about 6 ft at neg low at this one spot
I went out and bought an electric hookah - went back there and just beyond that area - in like 7 ft of water at low
I got 3 more old gold and some barber coins --Soooo
All you got to do is get out beyond everyone elses limits - ton of our beaches had raft/platforms way back when
most were probably within 10 ft deep id say - that's where you want to get
