So ya do the manta dive just after sundown, run back to teh dock, it's not far and drop off everyone else. Then you run out past the 1000 fathom line at 10ish at night, clip off to a control line, yes you will need it, then jump into the inky blackness and hang there while some realy awsome critters come visit. Squid came by, got pics of a seahorse, in 7000 feet of water! I never would have guessed! Syphonofors (sp) jellies....The manta dive is awsome and rated as the number one night dive in the world, the black water is 10X better! Search blackwater here and you will find the other thread with pics.
