OK for practice. Viz was terrible at 10 ft, even though we were the 2nd group in the water. Most of the sunken items weren't interesting, as most are barely recognizable (terrible viz & coverage by the green growth). In order to find some of the sunken items, you need a compass/slate to go along with the online underwater map. Fish are intensely interested, until they figure out you're not going to feed them...then they split. Still a pleasant day. The shop is nice, but small. They rent only steel 80s...no AL 80s.
