what does "Full Function Air/Nitrox Dive Computer" mean?

[s.s.seafan]

Hi,

I am looking to buy my first dive computer, for a typical listing like the following on an online site:

Full Function Air/Nitrox Dive Computer
Visual Alarm (ascent)
Manual and water activation
Diver-replaceable batteries
Ascent rate indicator
Nitrogen bar graph
Depth to 330 feet
Automatic Altitude Adjustable
12 Dive log
Time-to-fly
Time of day (use it like a watch)
Imperial/Metric (user-setting)

What does that "Full Function Air/Nitrox Dive Computer" include? I assume it records a graph of depth/time? does it record surface interval time? does it display how much time left due to DCL?

and what is "Nitrogen bar graph"?

thanks,

-Jason

....What does that "Full Function Air/Nitrox Dive Computer" include? .....

it means you can use it to plan and execute dives using Nitrox (aka Enriched Air)

....and what is "Nitrogen bar graph"?...

it is a graphical indicator of the estimated amount of nitrogen in your body

do you know the model of this dive computer? Maybe we have videos for it.

Full function = "Please buy me."

Nitrogen bar graph is a graphical representation of your body's nitrogen uptake. Sometimes this is shown by tissue half time, but more often by a single bar moves up and up and then goes into a yellow zone and finally a red zone to indicate that decompression is required.
