The instructor has Gotta be Capt. Russ Fleming you are talking about.
He's an ex new jersey state trooper. great guy and superb instructor.
Did my OW,AOW,Nitrox, and getting ready to do my EFR and Rescue with him this coming spring..
Last time I went to the Sherman, Capt. Russ rolled off the side right on top of a BIG Tiger shark.
There is also usually a really big sand tiger female that is known to haunt that wreck also.
The newest thing is the 100ft. Charleston tug boat.
About 2 weeks ago, They just sunk it close to the barracuda alley wreck in 60 fsw.
Can't wait til the water warms up to go back.
