    but they would not consume enough air to get into trouble during the whole film's runtime if they would lower their SAC by using fins :popcorn:


    I wonder why they even bother writing these scenes happening underwater in the first place. The cave sharks could as well fly mid air if they just want to do unrealistic and entertaining stuff

    It operates exclusively on PSI/BAR per minute.

    Here are the calculations that the Teric does for the SAC rate, and then how it calculates the gas time remaining. Screen Shot 2019-08-28 at 11.14.53 AM.png

    Thanks -- that all makes sense. I'm a little embarrassed by my question now, so I appreciate the remedial math lesson.

    Anyway, to get somewhat back on topic, I guess the spgs in the movie could pretty easily display percent of air remaining. Why you would want that instead of estimated minutes remaining, I'm not sure. Except that if you did it as minutes remaining the audience would probably be wondering why the gauge only went down 10 minutes in 20 minutes of movie (as they were going deeper and swimming harder).

    Just watched this garbage for the entertainment value last night on Prime. What garbage... Dang, a blind great white in the Yucatan, constantly eating every human it sees. AMAZING. :banghead:

    I "watched" "47 Meters Down: Uncaged" last night. Good thing my focus was on playing hearts on my laptop instead of the film. Otherwise it would have been a total waste of my time. I wonder what the girls' SAC rates were to have their tanks last so long. Good thing to see GWS aren't just man eaters... they'll take a bite out of a woman too (although most of them survived being held gently in the shark's jaws).

    I haven't watched either movie and really don't plan too but I was curious about the full face masks used in both movies. What company makes them? Or are they just a Hollywood created mask similar to the SPG?

    Scubapro had this already in the seventies. It was called the Dive Timer. Here from the 1979 catalog:

    SWEET...... I love a good stupid comedy! Guess that’s why I am a Monty Python fan.
