I dove a deep hole that is 70 feet deep today. I found these three 5″ killer teeth. Most of the dive was in the sand and I had to swim around until I found a spot with a hard bottom. I found two teeth just inches apart and I figured I was going to find a bunch. A few minutes later I found the largest one. Because of the depth my dive ran out way before I wanted to come up. They measured 4.91″ 5.53″ and 5.82″. It was a great dive.
