If you are down in the keys Capt Hook's Scuba's your one stop shop and dive's. All three locations offers a different experience in the water.
Key west has the Vandenberg a wreck that is 520 feet long and sites around 95 TO 100 ft. depth to it's deck. They said its the largest most accessible artificial reef.
Big Pine has the Looe Key reef it is a Sanctuary Preservation Area that is home to many amazing marine wild life. This location is rated #1 in Florida and #10 around the world. I loved my dives there so much I went back 3 times and each time was like the first.
Capt Hook's Marathon is no different they the first two many locations and top notch staff. I dove a ship wreck called the T-BOLT. I was welcomed by the crew and enjoyed the day in the waters with other professionals who also enjoy a good wreck and marine life.
When in the keys their is no one with a better safety record, more professional or experienced then Capt Hook's.
