How to read these results


Your respiratory minute volume is L/minute and you want to dive at a maximum operating depth of meters.

Using a tank that’s initially filled to bar will allow for a bottom time of ~ minutes until you reach the safety reserve of 50 bar.

The expected air consumption during this time is L.

Please note that these are only estimates and by no means replace a thorough dive plan!

How to read these results


The respiratory minute volume tells you your average consumption of air while scuba diving. 

It can be used to quickly make estimates on how long your tank will last underwater and help you in your dive plans.

During a previous dive to you used a L tank with a maximum tank pressure of bar.

The dive lasted minutes and you used up bar.

This leads to a respiratory minute volume of L/min. So, on average, you use up   liters of air per minute when you’re underwater.

If you had spent the entire dive at the surface, the equivalent surface air consumption (SAC) would have been liters.

You can now use these numbers in the calculator above to plan your dives.
