The Tusa IQ-750 Element II Wrist Computer can be operated as an Air computer, Nitrox (EANx) computer, digital depth gauge/timer or as a free dive depth gauge/timer. The Tusa IQ-750 Element II Wrist Computer offers several desirable features including: Water-activation, 2 Mix Gas Switching ability, a large alphanumeric and backlit display, audible and visual alarms, advanced user safety settings, and PC download/upload. In addition to offering the latest comprehensive computer features, the IQ-750 adds a Deep Stop function for enhanced safety.
Deep Stop Function
Tusa IQ-750 Element II Wrist 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, 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.

TUSA’s computers feature audible and visual alarms for the most important dive data warnings. Ascent rate, maximum depth, no decompression limits, safety stop and several other key data can be set to alert the diver.
Several TUSA computer instruments feature a backlit display for night diving or low-light situations. The bright backlight is activated by a touch of a button and the duration can be set for up to 10 seconds in length enabling the diver to view critical dive data easily and quickly.
Optional Deep Stop
An optional safety stop on No Deco dives exceeding a depth of 80 feet.
TUSA’s PCLogbook and TUSA DataLog PC interfaces allow the diver to transfer complete log and profile history from the dive computer to a personal computer or upload user settings to the computer. A PC interface unit is sold separately.
User Replaceable Battery
Convenience and ease-of-maintenance is imperative in the design of today’s dive computer. Each of TUSA’s computers offer a user-friendly replaceable battery that can be changed on a moment’s notice using standard widely-distributed batteries.
