As far as I can tell, they, Nautical Divers, are the only charter out the Jax area.
I have found a couple, one has a history lol, and the other is not running at all now.
If anyone knows of another, please let me know. I have been up in N FL a year now from Broward and would love to able to get ocean diving in within striking distance of me. Jax is just shy of 2 hrs for me. I know I can run to Tampa, but that's a little over 3 hours.
The price seems high at first, but 3 dives, about a 10 hr day, fuel ect. I would think they would offer a 2 dive trip, close in for less at some point.
