EAN 39 Equivalent Air Depth at 25 meters
At 25 meters depth with EAN 39, the Equivalent Air Depth (EAD) is 35.3. This means breathing EAN 39 at 25m feels like diving at 35.3m on air, providing a nitrogen reduction of -10.3 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.
