Nitrox computer for a novice...

[DiveNav]

I'm doing some research on getting my first comp. .... .......

I suggest you take a look at the Dive Computer Research Tool.
Some of the dive computers in the tool have videos/classes to show them in action.

Rongoodman......you had better explain why you would avoid Suntos pretty quick or the opinion police will be after you aswell!!!

Endless speculation about what Suunto's proprietary algorithm is or how it works. Too much mystery for me.

Mares Puck is one of the best entry level computers out there. Intuitive, simple to use, affordable and handles Nitrox with ease. Also comes with a scratch guard, great backlight and converts to bungee mount without buying any additional items sans bungee cord.
