It had been awhile since I had been in some sort
of back inflation device. Previous setup was
Scubapro Classic Jacket. So getting used to the
buoyancy shift was the biggest difference. Also
getting the shoulder straps to proper tension is
important. I had them too loose to begin with
until my first GUE class.

I dump air out the BC using the dump/inflator
device at the end of the hose. Normally I just
hold it up and dump. To get every last bit of air
out I maintain horozontal postion but roll my body so that the left side is bit higher up.
Ascent should be made in the horizontal position
as the increased surface area to the direction
of travel helps you to maintain ascent rates
and "safety" or deco stops.

I have seen divers pull their BC hoses off.

I have never used them myself, although I
guess I do have a set of DiveRite superwings
in storage with them. Dual bladders even.
Need to be listed in Ebay one of these days.

Snorkels are a pain in the rear for SCUBA diving.
Worthless thing dangling on the side of your
head. When I swim on the surface with SCUBA, I
am always on my back, better propulsion with the
