Well as far as I know recreational diving ends at 130 ft. Period. I've dove The Diane and The Bibb in the FL Keys where the floor is at 120/130ft. almost no one touches the sand as all that does is kill your bottom time. Instead we dive the decks at between 70 and and 105 ft. Help we out someone! Although I would love to see 130' no dive operator in his right mind would let the group anywhere past 110 feet. May be I'm wrong and if I am please let me know and I will certainly bring my backup dive computer with me.
