The IQ-900 can be operated as a Watch, Air computer, Nitrox (EANx) computer, Digital depth gauge/timer or as a Free dive depth gauge/timer.

The Zen's large alphanumeric and backlit display allows for high legibility in or out of the water, although its size is that of a normal style watch!
In addition to offering the latest comprehensive computer features, the Zen adds a Deep Stop function for enhanced safety.

Deep Stop Function.
The Zen computer features an optional deep stop function for additional safety. The deep stop mode is activated when a dive exceeds 80 FT (24M) for more than 1 second. Upon ascent past 50 FT (15M), the computer will display a Deep Safety Stop screen and the recommended stop at 40 FT (12M) for a period of 2 minutes. This deep stop is highly recommended as additional opportunity to off-gas, but is not mandatory.

    Computer Failed on First Dive

          Comments about Tusa Zen Wrist Dive Computer (IQ-900):

          Computer failed the first time I used it! Got some crazy error message halfway into the dive and it stopped displaying/recording data. It did the same thing on 2 subsequent dives. Sent it back to Leisure Pro more than 2 months ago and don't have it back yet. You would think they would just replace it and apologize.

                  After 2.5 year the watch is dead.
                  No more warranty.
                  The repair cost about 150 euro and 3 month waiting.
                  It is worthy to buy another brand.

                  I'm happy with this divewatch computer. I also had a Citizen Promaster Cyber Aqualand Nx Dive Computer Watch which is superior but not by much.

                  It can't be used (daily use) as a watch due to its big size.
