- Reading my Basic Scuba book, there used to be quite a selection of CO2 activated emergency flotation devices to choose from. From the cheapy "Res-Q-Pac" to those neat Sea Hunt Markers and the Dacor inflatable waist belts. NONE of these are available today... Probably for liability reasons and lack of "Coast Guard Approved" status.
- With single tanks, I've been using a small (18 lb lift) Oxycheq "Traveler" wing BC mainly for it's emergency flotation capability... And planning to inflate it orally since it has no CO2 and my vintage regs have no inflators.
- But since I got my Twin 38s, I've been going without emergency flotation.
- Recently I came upon some actual Coast Guard Approved, CO2 emergency flotation that is not much bigger than the old Dacor waist belt flotation. The labeling is from both Stearns and Coleman and the brand name is SOSPenders.
- I ordered and received one of these. Quality is excellent. It's not bulky at all. The volume of flotation is plentiful. And it re-arms with standard 16 gram CO2 cartridges... Yeah, it's re-useable!
