This reminds me of a dive guide who I was with a couple of months ago...the first part of the dive was in waters 50 feet deep, ending in maybe 30 foot deep waters....his tank lasted him 90 minutes...
When you dive enough and are relaxed enough, your air lasts far longer....

My SAC (Surface Air Consumption - Equivalent) rate can drop as low as 8.5LPM (Litres per minute) or 0.3 cuft per minute.Originally Posted by The Publisher
If you keep fit and dive a lot you will be able swim around, even against a current, and still use very little air. Trim is very important.
