Ditto on Gary at Counch Republic, Ocean Divers is good but sometimes the boat is crowded.
If you venture south do not use Looe Reef Resort. 6 days a week they go to the same site, move 100’, move 100’ and call it a 3 tank dive. You can do it on 1 1/2 tanks. The crew is busy selling chicken dogs so don’t expect them to help you back aboard or watch your bubbles. Back at the dock the dive Nazi makes you stand in line to make sure you are not trying to steal her rental gear even if you didn’t rent gear.
