One factor I considered when buying regs a few years back was how the shape
(design) of the first stage might make it easier or more difficult for an
out of air diver to find the mouth peice and get a breath. I wanted a reg
that had an angled purge button/diaphragm to prevent free flow in strong
currents but was concerned side breathing (if this is the correct term) regs
such as the Posiedon Jetstream and one Oceanic reg I looked at, being an
unusual shape, may lead to difficulties in buddy breathing or when an out of
air diver takes your primary or occy. My theory was this:
Regs used by most recreational divers have a purge button on the
front, a roughly circular case and the mouth peice is generally in the
centre line near the top of the case. An out of air diver (I deliberately
avoid the word panicked) diver who is used to this type of reg design may
have some difficult (even just momentary) in finding the mouthpeice of an
unconventionally shaped reg and perhaps this brief delay could make the
difference between them taking a breath or bolting for the surface (if
available).
I beleive someone mentioned earlier that with this type of reg there is no
real right way up so the person donating a reg could simply take it out
(Oh!!! touchy subject, just got into an intense (not quite heated)
discussion with one of the crew from my local dive shop on this topic today)
flip the reg over and stick it in the out of air divers mouth. This may
negate the problem (if in deed there is a problem). I don't use this type
of reg so any comments? (I will not be too put out if my theory is a load
of old cobblers but it would be good to hear from people using this type of reg)
