OW Training Intro

Scuba diving is an underwater adventure sport. Scuba diving takes you into the underwater world for glimpses into an exciting environment for exploration and discovery. “SCUBA” stands for Self Contained Underwater Breathing Apparatus, and allows you to descend below the water’s surface for an exciting and rewarding experience. Divers are generally hooked on the sport after their first dive!

To dive, you need to be certified. The first certification you must aquire is a Basic Open Water certification. There are many elements of diving and diving safety, so getting the proper certification and training is essential before making the plunge.

Ascent Rates

We all remember from our open water training that our ascent rate should not exceed 60 ft/minute. Some of you may have read or heard about more conservative recommendations for ascending from a dive.

Chris, is a diving prodigy from Florida, but has traveled extensively all over the world. His love of underwater photography gradually developed after his father, Blaise, helped get him certified as a diver at the age of 12.  After receiving a 2-mega-pixel camera and an Ikelite housing from Blaise, his career had finally begun. He became much more accomplished after completing his first class with Stephen Frink in 2005. After the improvements made in that short week, Chris knew photography was his future.  Chris currently shoots a Canon 1Ds MarkII with a Sea Cam housing. Chris has been diving in extravagant places such as, Belize, the Bahamas, Utila, Roatan, the Galapagos, Fiji, and the Florida Keys.
