1st stop spent 2 hours in the water, no finds worth keeping, when I got out I notice 5 people detecting the beach, an this was a small beach, so I went down the road an while I was busy digging up my first hit, I thought I saw something an I about jump out of my shoes, there was a school of rays about 4' from me just flaoting in the water watching me an for the rest of the day everytime I would start digging the rays would show up, some schools had at least 20-30. Well I soon got use to it an kept hunting, then about 3pm this lady starts yelling at me an I take off my headphones only to hear the word SHARK .He was about 6' an about 30' ft away.I was in knee deep water an so was the shark,I am sure he was after the rays( shark food), but I kept a little closer to shore after that.
