The question is as follows: bearing in mind that for a time I shall be using the unit on multilevel dives, not deeper than 30 meters, with no deco, do you think that carrying bailout is necessary?
Lets see,
Dive you could do on a single tank: check
Normoxic dil: check
More bailout (in onboard dil) than a spare air: check
As others have said, carrying a 40 is simple and good practice, but I wouldn't bother. No deco (or light deco) wall dives I'll bounce down to 50 without offboard bailout. Diving with the mother of my son, when she's on OC, I take bailout.
