How Long Will My Tank Last

We get asked all the time, just how long will that tank of air last you under water?  Factoring in our depth, SAC Rate, and for safety a third of our tank volume, we can determine how long a tank of air will last us.


SAC RATE Calculation
Air Used / Time At Depth / Depth In ata

Rule Of Thirds
Working Pressure / 3
