On a deep dive where I dont want to be dragging lots of bottom bail gas around It can enable me to take the option of swimming back to the realtive safety of the upline instead of doing an imediate ascent in what can be unfriendly conditions.

Ages ago, long before I got a rebreather I recall seeing online a nice spreadsheet for SCR bailout. IIRC it had "Planned drop in PPO2" across the top and "Depth" down the side. So you could choose to except a larger % drop for higher number of breaths between vent & refill of the loop or very few SCR breaths for very small changes in PPO2...

I may have got that all ar*e about face but I guess you'll know what I mean...

Anyone like to venture whether thats a good idea and if a modern equivalent exists?

Thanks,
BEN
