Blue Reef Waterproof Log Book
Divers are required to log their dives for proof of experience; this handy waterproof 5"x6" 55 divers log book allows you to write down the important information while you're still wet, thus eliminating the possibility of forgetting important facts about the dive and instrument readings included in logging a dive. Why wait until you're more likely to forget something, so "git-r-done."
