I just spent this past weekend (Fiday, Saturday and Sunday) diving with Conch Rebublic Divers. It was my first time going out with them - Had an amazing time! We dove the Duane, Eagle and the Speigel Grove, all on rebreathers! They were even able to accomidate us rebreather diver's request for longer dives, so they scheduled double dives on most of the wrecks, which gave us the option of doing two dives or one long dive - We picked one long dive of course!
Captain Gary and Brenda were EXTREMELY accomidating with ANYTHING we needed!
If you're thinking of diving the Keys, my first call would be to Conch Republic Divers!
I intend to post a more detailed trip report, but I still haven't loaded all my pictures online so I can post them along with the report.
