Katy B Does this measure Nitrox?
RICHARD C I never dove nitrox, and as far as i know, this computer is only good for air.
MICHAEL B Katy,
No it doesn't measure Nitrox.
Mike
ALLAN S The computer does not measure Nitrox. Before each dive the O2 level must be entered. The computer based on the O2 level entered uses the appropriate algorithmic to plan the dive and comput dive time.
PATRICK M No this computer is air only. Another issue with is no back lighting. I recommend the air integrated models. I've made hundreds of dives with no problems from the three I own. I also use a xr-2 wrist model as a backup on deeper dives
ROBERT H No. The XR-2 does. This is an otherwise reliable and very easy to use computer for a broad range of diving activities. It's a great bargain, though the XR-2 might be what you're looking for.
