Cool Factor: If you can’t see this, you can’t see anything.

Key Features: In contrast to the current crop of downsized wristwatch computers, Tusa’s IQ-800 features a large, easy-to-read screen housed within an ultra-thin case. The computer's advanced software package is based on a 12-compartment Swiss decompression algorithm, and supports both air and nitrox diving with full decompression capabilities. Bold bar graphs located on the screen's perimeter provide at-a-glance monitoring of nitrogen uptake, residual oxygen loading and ascent rates, while alarms can be provided as audible or vibrating prompts. A large capacity memory stores up to 30 hours of data.
