Important Safety Note.
This page is not intended as the only means of calculating Nitrox Blends, Max Depths, EADs, or other information for planning of Nitrox dives. It is only an aid to check calculations that qualified Nitrox Divers and Blenders perform. Formula's such as these are no substitute for proper training. I accept no responsibility for any individual who is injured or causes property damage by using these calculators. If unsure of anything on this page contact your a local dive store (Try Plunge) to inquire about Nitrox Training.
