Streamlined design with essential dive functions
Designed for divers who value clarity and simplicity, this wrist-mounted dive computer features a high-contrast Chip-on-Glass LCD display for excellent underwater readability. Its two-button interface allows seamless navigation across all settings and modes, both at the surface and during dives.

Versatile dive modes and decompression tracking
Offering Air, Nitrox, Multigas Nitrox (up to 3 gases), Freedive, and Bottom Timer modes, it supports a wide range of diving applications. The system operates on the trusted Buhlmann ZH-L16C algorithm with user-adjustable gradient factors for personalized decompression monitoring. The optional Safety Stop+ function enhances post-dive safety by automatically suggesting a deeper extended stop based on real-time ascent data.

The onboard memory stores up to 100 dives with detailed graphical data. Powered by a user-replaceable CR2450 battery, it supports up to 100 dives per cycle and includes everyday features like alarm, date display, and countdown timer.
