pilot fish:Rock, are you saying the DM acted unsafely when he instructed the hoover to breathe off his octo?[ what was his psi at that moment?] I'm not sure about that one myself. Just off the top of my head I would think it wiser if he told the diver and hoover to ascend to SS. As far as not taking the camera, I think that was a wise move on the pat of the DM.
PSI is irrelevant since his octo is designed for emergency. Extending a person's dive does not qualify. I agree with the second part of your post.
