Did my SSI Divecon years ago
Assisted on 1 class and said stuff that after a big student latched on to me (playing with his fancy reg and turned the air flow down) - not sure who's eyes were bigger!
Why worry about sharks, we are soooo noisy underwater bit hard to think we are food - free divers thats another thing (maybe) - I say its the one you don't see that gets you, if you can see them not too worry (unless you carrying the bag or fishing of course)
