| Like Janos says, I've got the RB. The scrubber will last 4hrs, the O2 about 10hrs on a full tank. I usually carry a small tub of lime enough for a refill for diving use in case of a flood or whatever so I can always refill the scrubber if somewhere remote. I also generally carry a 7 or 12 of O2 as well having been in the situation of having to drive myself the two hours to the chamber. The small bottles in O2 kits are never enough, even if you're just waiting for an ambulance.
