Here are some comments on the picture of Billy B Mix in Scientific American.
Just something to mull over.
Mitts- makes un-clipping reel, liftbags, regs rather difficult. If the water is
that cold, here are the Poseidon ice caps.
Clip on shoulder strap- plastic, weak point.
MOD on cylinders so small almost undetectable. Hard to check diver from
distance.
O2 cylinder same colour as nitrox, and big enough for hundreds of minutes of
deco.
Nemesis dive computer-(replaces SPG) any pilot will tell you how much better
digital is over analogue or determining status at a glance. NOT.
Free diving fins. BC inflator covers Drysuit inflator, making detachment of
same difficult in an emergency.



BC inflator hose covered by neoprene, making
detachment in an inflator failure more difficult.
Using "bungeed" wings, presumably more difficult to orally inflate in
 emergency.






And most American of all use of manifold for open water dives where it is usual
to be solo diving, or is easy to be separated from buddy.

Apart from that, I like the EPIRB.

Rod Nairne.
