EAN 27 Equivalent Air Depth at 13 meters
At 13 meters depth with EAN 27, the Equivalent Air Depth (EAD) is 11.3. This means breathing EAN 27 at 13m feels like diving at 11.3m on air, providing a nitrogen reduction of 1.7 meters.
What is Equivalent Air Depth?
The Equivalent Air Depth (EAD) is the depth at which breathing air would produce the same nitrogen partial pressure as your Nitrox mix at the actual depth. It allows you to use standard air decompression tables while diving with Nitrox.
