Underwater safety is at the core of the Tusa IQ-850, as it incorporates an advanced decompression algorithm based on scientific data. The computer performs continuous real-time measurements, accurately determining the no-decompression limits (NDL) and the necessary safety stops during ascent. The system adapts to your personal needs, allowing you to input conservatism factors for even safer underwater journeys.

For divers who want to extend their time underwater and reduce nitrogen absorption, the IQ-850 offers full compatibility with enriched air mixtures Nitrox. It allows you to program the oxygen concentration from 21% to 50%, as well as set the maximum partial pressure of oxygen (PO2). In this way, the computer instantly adjusts the diving profiles, providing complete flexibility for different diving scenarios.

The digital display of the watch is designed for optimal readability, dividing information into clear zones. With a quick glance, you can check the current depth, remaining time, water temperature, and ascent rate. For dives in low-light conditions, such as caves or nighttime, the built-in backlight illuminates the dial evenly, ensuring excellent visibility.

To prevent errors and ensure safety rules, the Tusa IQ-850 features an advanced system of audible and visual alerts (alarms). The computer immediately warns you if you get too close to decompression limits, if you exceed the allowed ascent speed, or if you approach the maximum depth you have set. These immediate alerts allow you to stay focused on your exploration, knowing that you are protected at all times.

Made from reinforced high-strength materials, the watch offers guaranteed water resistance at great depths and withstands the wear and tear of seawater. It features a spacious digital logbook that stores data from your recent dives for later analysis. Its durable strap ensures a secure fit over your wetsuit, while the long battery life guarantees the device will always be ready for your next underwater adventure.
