The O2ptima is a fully closed mixed gas closed circuit rebreather. Unlike other products both past and present, this design represents the collaboration of several manufacturers within the diving and safety industries. Each company was able to bring their strengths to this product, increasing safety and reliability. While many designs have needed to evolve over the years, the O2ptima at its release, represented some of the best technology available.
Dive Rite has a long history of serving the diving community with innovative and quality products. Unlike many other companies which concentrate on a specific market, Dive Rite has excelled in delivering products to the recreational diver while still being able to supply cutting-edge equipment for even the most demanding diver.

Southern Maryland Divers provides CCR training on the Dive Rite O2ptima rebreather. While we strongly encourage that you purchase a unit to complete your training on, we also have a rental unit in stock for training as well. We can also outfit you with a new O2ptima when the time comes, so before you shop somewhere else, please contact us first.
Rebreather training is taught on demand, so if your ready to start the exciting transition to the world of silent diving, give us a call so we can setup your class.
The class requires a full day of classroom time which includes the academics as well as full tear down and rebuild of the unit along with pre-dive checklist and troubleshooting. After the classroom is done, we will spend at least 120 minutes in the pool, and then over 6 open water dives, we will spend at least 500 minutes of bottom time.

Rebreather diving is a phenomenal experience that allows divers to enjoy the underwater realm like never before. Whether your interest lies in up-close-and-personal wildlife encounters, amazing photography opportunities or furthering an exploration, rebreathers offer something for everyone.
Today's rebreathers are easy-to-use, yet as more and more brands hit the market, the choices and options can be overwelming. Semi-closed circuit or fully-closed? Electronics-driven or manual? Granular scrubber or cartridge? It can be a minefield that's not easy to navigate.
