MX Rebreather - SPG for O2 Supply/Bailout Deco
We need to have a pressure gauge on any offboard supply/bailout
bottles to ensure that we have enough gas to conduct the dive and
if we need to bailout. The SPG is stowed on the bottle in the
standard UTD/DIR configuration, having the SPG attached to a
6”/15cm HP hose and then bungeed and folded back onto the first
stage to remain in full view of the diver at all times.
