How long does a SCUBA tank last? - Gas Calculation for Scuba Divers

#scubadiving #divegue #gueheroes This video answers the question every diver is asked by non-divers sooner or later: How long does a scuba tank last? If the person is really interested I always start a very simplified version of GUE's gas calculation for scuba divers using the CAT formula to quickly estimate your necessary gas reserve and alongside with that, the expectable bottom time. For scuba divers, it's vital to realistically estimate the necessary gas reserve, called the Minimum Gas, becuase this is what ultimately limits the dive time or essentially, what non-divers mean by asking, How long a scuba tank lasts. 00:00 Start 01:21 Available Gas 02:18 SCR and DCR 03:57 Minimum Gas 07:18 Practical Tips Please note that this video is not the entire part of the gas management lesson taught during a Fundamentals Class. It's just a very simplified, quick explanation. If you like to know more about gas management, subscribe watch my other videos or even better, consider taking a fundamentals class with my or any other GUE instructor.
