How long does 1 dive last?

The average beginner diver's air consumption in calm waters runs a tank close to empty in around 1 hour at 10m depth (compared to just a few minutes at 40m). Professional and very experienced divers can usually double this time through breathing/buoyancy control and by minimizing the amount of movement underwater.
