The Mares Sirius is the latest watch-type dive computer designed for recreational, extended range and open-circuit technical divers. This elegant dive watch features a high-resolution MIP colour screen and a choice between three watch faces and different colour schemes, displaying standard dive information for recreational divers to on-the-fly cylinder pressure information from up to five Mares LED Tank Modules 2.0 for open circuit extended range and technical diving.

Mares Sirius - Dive Modes

The new Mares Sirius Dive Computer runs with Buhlmann ZH-L16C Algorithm and is boosted with Gradient Factors adjustments and Predictive Multigas setting. The Mares Sirius is loaded with Bottom Timer, Air, Nitrox and Trimix Modes for the main functions and a selection of up to 5 open circuit gas mixtures. This contemporary watch-style dive computer features a super helpful full-tilt digital compass with bearing memory and a stopwatch making this watch a handy tool for underwater navigation and no need for an additional analogue wrist compass.

Mares Sirius - Rechargeable Power Unit

The Mares Sirius Dive Watch is powered by a rechargeable 200mAh battery which should provide enough power for 15-30 hours of dive time - depending on power and wireless integration settings. The battery has a lifetime of up to 500 cycles. Each Mares Sirius comes with a wireless touch charging station for quick, trouble-free charging.

Mares Sirius - Connectivity

The Mares Sirius Dive Watch features a complete wireless tank data integration, allowing connection with up to five Mares LED Tank Modules 2.0. The gas mix management offers at-a-glance readability with colour-coded tank pressure, which is a handy function when using multiple decompression gas mixes. The Mares Sirous Dive Watch needs no interface cables as it connects to your Mac, PC or Mobile via Bluetooth.
