pSCR Rb
Decompression
As of today deco theory in general is not a 100%
understood science
However saturation dives have become more predictable
and easier to deal with, from the actual schedule planning.
Even do usually require teams to "stage" all the necessary
equipment
Ironically No saturated dives are harder to predict, but are
easier to do as require minimum equipment.
Decompression prediction is challenging especially if the
gas is changing during the dive, both in bottom and deco
phase, as it does on pSCR diving.
Furthermore your average OC rules will not mirror your rb
needs, and could end up becoming inneficient for proper
decompression.
In fact DCS in not trained pSCR trimix rb divers is quite
common.
Here are 10 rules for rb80 diving :
1. Get proper rb training. don't just get the c-card get
someone that actually dive extensively the unit in YOUR
conditions. Also dive within your training limitations a rb
nitrox course is not intended to cover rb trimix diving.
2. Learn to decompress in OC first, as if rb breaks down
you are back to OC or death
3.One key is staying warm,
one of the reasons to use the rb and
it goes as far as electric heating and/or Habitats.
4.Standardize mixes and repeated profiles, this where
experience in the unit comes handy as you don't have to
start from scratch the trial and error process.
5.Dive Analisis, key in the learning process, use tools as
Touzil System. Always know your MOD and MinOD
6.Fitness, should be at the level of diving desired to do
7. A 5:1 ratio normally achieved within 50hrs of rb time
prior deco, you don't want to learn to dive the unit at depth
on deco dives, you may want to have your first failures at
shallower depths and get use to the breathing and rb use.
8. Avoid diving with OC guys while using an rb
9. Use a scooter, reduce effort
10. If you been "bent" in the unit go back to number 1

150minutes bottom time between 45/60mts at 8°C
70minutes bottom time between 200-345 ft at 24°C
