Hmmmm,
A little ambiguous,'oxygen providing rebreather equipment' could (and probably does) imply just the hand sets.
My two concerns here then (and I talk from experience) would be handsets swithing themselves off (bounce) ...... know your PPO2 aside.
and ..... where a rebreather goes to confirm it was working prefectly well .... the manufacturer?! An independent would be my preferred option for an unbiased report.
No disrespect intended to anyone.
good points.
as for the first one, the known battery bounce issue that has come up does seem to leave this possibility open and unresolvable unless AP or family were to release the log...if there is any log of that dive then he turned the handset on.
on the second point, better protocal would be to have it first inspected by an objective third party but is there truly such a person in such a small niche. Certainly in this case a log of the dive would be very telling at the very least.
