Versatility is the key to the Zen IQ 950 Zen Air, which can be used as an air/nitrox computer, depth gauge/timer for free diving, or as a watch for daily wear. Functionally, the Zen Air offers three-gas, three transmitter capability, up to 100 percent nitrox, and adds a Deep Stop function for enhanced safety: Exceed 80 feet for more than a second and the Deep Stop reminder is activated. The large screens make it easy to read critical data like air pressure, depth, no-decompression limits and bottom time, and at night, the backlight illumination ensures the data is still discernible.[
