Two dead at DaXing spring cave, China

[Manatee Diver]

Looks like they are basing it on the HUD from a GoPro video.

I don't know about anyone else, but when diving with a CCR diver, I always ask what is the emergency procedure for the unit. Is there a BOV or a dil flush I need to know about.

It sounds like the OC diver tried her best to do the right thing up to the end. Very sad for both parties and families.

I am not quite sure that facing such situation: high risk to lose guide line or try to save an unconscious buddy, which one is priority? it seems quite a hard decision.
