Who disagrees with DIR and why?

Except the long hose is twice as long as your octo hose. Also the primary was tested 5 seconds before handing it to the OOA diver. The same cannot be said in most cases for an octo.

If you want to assume toe octo is bad then I can assume your backup is bad and now their are 2 paniced divers as the first was out of air and took the only good air source from his buddie.

Your assumption supports donating the primary. Let's say your assumption is true: both divers have a non-functioning backup reg. Then donating the primary is the ONLY course of action.

If we create a matrix of all the possiblities (i.e., both divers have working backup regs, one diver has working backup reg, no divers have working backup regs), you will find that donating the primary works in every case. Whereas donating the backup/octo will fail in some cases. Why not simply follow a process that works in every case?

If both backup regs fail then you would have to buddy breath. Remember this from the OW pool class? This is a good skill to practice from time to time. I can understand how a diver might panic if not prepared for this possiblity. But that is a deficiency in the diver, not the process.

I hope somone is not diving with a 12 foot hose (twice the lenth of my octo)
and I rember buddie breathing from Sat. when my buddie and I did it from one of the platforms in Squair lake to shore (on a short hose ) when buddie breathing I stay close to my buddie not 7 feet away.

my main problem with breathing the long hose is I have nothing on my right side to route it around so it floats lose. I also don't have the money for a canaster light.
I also donot like the fit of a standerd backplate I find them too short for my body. if I adjust them lower then the short inflater hose DIR calls for is almost unreachable. and I donot see what I could do with a BP that my BC can't do.
