Tusa IQ 900 Zen Computer

The IQ-900 Zen is TUSA's latest full-featured wrist-top, watch style computer. The Zen is a stylish instrument that can be worn at the office, on the town or in the ocean - anytime, anywhere the Zen is your go to timepiece and dive instrument.

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

Several TUSA computers feature 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, the computer will display a Deep Safety Stop screen and the recommended stop depth for a period of 2 minutes. This deep stop is highly recommended as additional opportunity to off-gas, but is not mandatory. If the diver chooses not to serve the stop it will not adversely affect the remaining No-Decompression Limits of the dive.
