Serious divers, meet your new favorite piece of gear! The Mares Sirius combines top-tier dive technology with a sleek watch-style design you'll actually want to wear. The ZH-L16C algorithm with gradient factors gives you incredibly accurate decompression calculations, whether you're doing recreational dives or extended range adventures. You can program up to FIVE different gas mixes - nitrox and trimix - making this perfect for technical divers. The color display is crystal clear underwater, and the digital compass with bearing memory is super handy for navigation. Want tank data? Add the optional transmitter for wireless air integration that shows up in easy-to-read color codes. The 100-dive logbook with graphs lets you review your adventures later, and Bluetooth connectivity means you can sync everything to your phone. Battery life is impressive too - 30 hours of dive time per charge. The changeable strap works with any wetsuit thickness, and the underwater menu lets you adjust settings right during your dive. From predictive multigas capability to the smart battery management, every feature feels thoughtfully designed for real divers. If you're ready to upgrade from basic dive computers or want one device that handles everything from casual reef dives to serious technical exploration, the Sirius delivers professional features in a package that looks great both above and below the surface.
