During a dive a few days ago my system (abyss) was significantly harder
to breathe during the entire dive. Conditions were as follows:
Air temp: 5-6 centigrades below freezing.
Water temp : at freezing (ice "sludge" on the surface)
Depth: 100 fsw
Water: Brackish (baltic)
Duration: 32 min.
Regulator was probably wet from a recent rinse
As inhaled, i could hear the "wheezing" sound of the 1st stage filling my
hose *after* i finished each breath. It seemed like the 1st stage couldnt
really keep up with my demand. My first reaction was to signal my buddy
to check that I had really opened the bottle fully (which I had).
The feeling was just like when you have opened the valve partially.
Can this be attributed to freezing? (one would expect a free flow really)
I'm having the stuff checked and serviced and "anti-freezed" anyway but
i'd appreciate your views
