O2ptima Closed Circuit Rebreather – Simply Advanced

By

The O2ptima in my opinion is one of the most advanced, yet straightforward closed circuit rebreathers on the market. The simplicity of the O2ptima is why I trust it. No scrubber to pack and it’s ready to dive in 15 minutes, provided your cylinders are full. The new Rev D electronics answer many questions to function and features. The added features of the new Rev D are a bonus but the real changes are the configuration. I have had many requests from divers to integrate their dive computer into the unit, 4th or 3 celll monitoring. The current Rev C configuration splits the solenoid control and the DIVA/HUD function; the primary handled the solenoid while the secondary handled the DIVA/HUD (diver integrated vibrating alarm/heads up display). To add another computer and cable turned the rebreather into an octopus.
The new configuration with Rev D electronics and sophisticated DIVA/HUD functions are on the primary and the secondary is strictly a 3rd cell PO2 monitor (optional deco if desired). If a diver has a dive computer with PO2 monitoring capability, the unit can be ordered with only the primary controller. If you want to upgrade an earlier unit, I recommend an upgrade to the secondary to get the new DIVA/HUD function if cost is a consideration, once you program a set point on the solenoid controller (primary) you can enjoy new PO2 display and DIVA/HUD via the secondary rather than the primary.
