Mares Genius Computer Black/Black with LED Tank Module

The Mares Genius Computer Black/Black with LED Tank Module is a versatile scuba diving computer designed for demanding divers. It manages Trimix and Nitrox dives with gas changes and uses data from up to five high-pressure probes to optimize bottom times and decompression. The color, scratch-resistant display is easy to read underwater, and the device can recalculate decompression times when gas changes occur. It supports a predictive multi-gas function and includes a built-in compass, with optional air integration and a rechargeable battery for ongoing diving sessions.

The LED Tank Module provides real-time tank pressure data with a color-coded LED system to quickly assess gas levels on the surface or during a dive. It is EN250 certified to 300 bar and uses a user-replaceable CR123 battery. The transmitter communicates with the main computer to deliver hose-less pressure display and gas-level indicators, helping divers manage gas supply safely during scuba trips.
