Coming Full Circle: Diving the O2ptima…again.

By October of 2007, I had become an Optima diver. Trading in my doubles for a rebreather was a careful decision; one involving research and asking questions.

During a dive, clipping gear to D-rings provides easy access to items we use most often. Reels, lights, primary SMB’s and line arrows are good examples of items we use often on a dive.
