TUSA is the world’s only equipment manufacturer with vibrating alarm technology. This patented unique alarm function is similar to the vibration setting on most cellular telephones. The user is alerted to important dive data with several vibrations instead of an audible alarm that can distract your dive partners.

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.

This feature allows the diver to preset two Nitrox gas mixtures (Mix 1 and Mix 2) for easy switching during the dive as necessary. Mix 1: 21 to 50%, Mix 2: 21 to 99%.

This advanced feature allows the diver to preset three individual gas mixtures (Mix 1, Mix 2, Mix 3) from 21-100% for easy switching during the dive as necessary.

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.

TUSA’s Zen Air Integration technology allows a diver to monitor depth, dive time and up to 3 tank pressures accurately and safely in a single glance. The need for bulky analog gauge consoles is gone. TUSA’s alphanumeric digital display conveys air data efficiently each updated second.

Hoseless transmitter technology combines the accuracy of air integration with wireless data transmission resulting in a next generation ultra-compact wrist-top dive computer – the Zen Air.

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

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.
