Billy Leslie at Hustler's is one of the finest instructors on the island. Their pier is located at the south end of town (by the Blue Tang Inn and Paradise Villas) however, they will pick you up at any dock.
Capt. Morgan's uses their dock as their departure site and Wet Willy's
bar and grill is on the end of the dock. It's fun to do the two tank morning dive with Hustler's as you can get a good lunch as soon as you get back.
One of the things I liked about diving with them is that I could leave all my gear with them and it would be dry and on the boat ready for me the next morning.
