Early warning before
the Incident Pit...
All rebreather divers agree that they need enough breathable gas, a working scrubber and battery power that will last the dive.
Each dive is spent monitoring these resources by contents gauge, O2 cells and maybe checking for headaches to detect CO2 (the ability of the human body to detect CO2 before problem levels is not reliable).
The Sentinel RedHead takes the legwork out of these checks by directly monitoring PO2, CO2, HP on diluent and O2, plus sofnalime temperature and battery levels, leaving you to focus on enjoying your dive.
When levels are normal, the Sentinel RedHead displays a green light on the HUD. Problems display as either a 'manageable error' flashing blue green, or a 'Bailout' flashing red, backed up by a patented buzzer. Further information to prompt fault finding and problem resolution is found on the handset. It's a very simple system that works.
The Sentinel RedHead is able to relate remaining CO2 'scrubbing' time to divers metabolic activity, giving accuracy of scrubber use that is not available on any other CCR. The harder you work, the more CO2 you will produce and the shorter your sofnalime will last. The Sentinel RedHead takes away the guesswork.
