How is an O2ptima different from other rebreathers?
All of the major rebreather models are good quality units. There is no perfect rebreather; they all have strengths and weaknesses that make each uniquely more or less suited to your needs. Beyond the features of the rebreather itself, you should consider the supplier along with how the model was designed and has been supported. Only a very few rebreather models are supplied by large and well-established dive equipment companies. The Dive Rite O2ptima is from a large US based dive equipment company in business over 20 years. As an independent dealer, we stock O2ptima units, spares and consumables with online ordering and same day shipping.
