How long do the Sentinel consumables last?
The manufacturer recommends the Sentinel CO2 scrubber duration be limited to 180 minutes at 130 fsw, based on CE testing with a CO2 generation rate of 1.6 lpm in 39°F water temperature. In practice, typical warm water Sentinel sport divers can expect scrubber durations in the range of four to six hours and battery durations of up to 60 hours on a single charge. The durations in actual use depends upon many factors related to the individual diver, specific dive conditions and particular brands of consumables. These are predictions based on experienced divers and in no way suggests exceeding manufacturer recommendations or that novices should expect these durations.
