Thread: Divers new product!

The addition of O2 into the breathing loop on this thing appears to be completely uncontrolled. The HUD electronics only monitor the loop ppO2 and CO2 but do not actually control it. So the device cannot match your O2 metabolic consumption and maintain the required partial pressure of O2 at any given depth. Instead, it’ll sound an alarm when the PPO2 exceeds a safe level, maybe 1.2 or so. For each user, this could be at a completely different depth to the next user. Ignore the alarm and you risk a CNS hit. There’s no bail out system to get you on a known safe mix. Pretty hopeful to suggest diving to 42m which exceeds “recreational” limits for most agencies. Probably fine to the 6m limit for pure O2 devices to be on the safe side.

I don’t have a problem with the principle, I dived using a Russian mine clearance rebreather (AKA60 Orca) recreationally for several years, this just needs better execution of the technology, perhaps in the form of a proper O2 set point controller.
