Sirius dive computer with LED Tank Module 2.0

Mares Sirius Dive Computer with LED Tank Module 2.0

The Mares Sirius is an innovative Mares dive computer in watch format, available in our online dive shop also as Mares Sirius without the Mares LED transmitter, a dive computer for technical diving, Nitrox and Trimix capable, featuring gradient factor calculation and hose-less air integration with up to 3 transmitters simultaneously.

Mares Dive Computer Sirius – Standard Features for Recreational Divers and Advanced Features for Tech Divers

Recreational divers will find all the necessary functions for relaxed dives in the Mares Sirius, such as a large logbook for up to 100 dives, a high-resolution and very easy-to-read colour display, temperature display, Nitrox with an oxygen percentage of up to 99%, simple dive planning, reliable alarm functions, and much more.

Divers who go beyond the limits of recreational diving and venture into technical diving will also find the Sirius very well-equipped, as this Mares dive computer also supports Trimix, can monitor up to 5 gas mixtures and up to 3 transmitters, features a precise ZH-L16C algorithm with gradient factor calculations for depth stops, and offers a predictive multi-gas function, decompression dive planner with surface intervals and other advanced features that advanced divers expect from their dive computer.

Dive Computer with Colour Display, Easy Operation and User-Friendly Menu

No diver wants to deal with complicated dive computer menus underwater, regardless of depth. The Mares Sirius excels here, as it is easy to operate and set up both at the surface and underwater. Navigation is carried out using four easily accessible buttons, located around the display, which can also be operated easily with neoprene gloves. The settings are straightforward and can be executed quickly.

The high-resolution MIP colour display is sharp and offers good contrast, remaining legible even in poor visibility conditions. The display is clearly structured and available in two different configurations, allowing you to monitor your dive parameters at a glance according to your preferred priority. Important information such as tissue saturation or dive profile is even available in a graphical representation.

Air-Integrated Dive Computer with Optional Transmitter – Up to Three Transmitters Possible

For more precise calculations of your dive parameters and therefore safer dives, use the Sirius as a dive computer with air integration by connecting it to the included Mares LED Tank Module. The Sirius can be paired with up to 3 transmitters simultaneously. To keep your air consumption efficiently monitored, the current tank pressure is displayed in colour-coded format.

Practical Mares Dive Computer with Integrated Digital Compass

For simple navigation and to minimise the number of dive instruments you need to carry, this Mares dive computer features a reliable integrated digital compass with full tilt compensation, bearing memory and stopwatch.

Wireless Charging and Data Transmission

Thanks to its intelligent energy management, the Sirius dive computer promises up to 30 hours of dive time on a single charge (without transmitters) and can be fully charged in no time at all on the included charging pad, without any cables.

Equally cable-free, all dive data can be transmitted via Bluetooth to a compatible device or updates can be sent to a dive computer.

Compact Dive Computer in Watch Format – Usable as an Everyday Watch

With its compact dimensions and sporty, attractive design, the Mares Sirius can also be worn comfortably as a watch in everyday life and impresses as such with three dial options featuring various colour configurations and practical functions such as a stopwatch, timer, or alarm.

Practical Accessories for the Sirius Dive Computer

For secure storage, the Sirius will be shipped to you in a high-quality, internally padded box, which also accommodates a matching extra-long replacement strap that you can use, for example, when worn over a thick drysuit.

The Mares LED Tank Module 2.0

The Mares LED Tank Module 2.0 is a highly advanced transmitter of the latest generation, which allows for hose-less transmission of air pressure from the dive cylinder to any Mares Sirius dive computer, functioning as a powerful transmitter with LED display. This makes your dive computer air-integrated in no time, significantly enhancing your safety while diving. The Mares LED Tank Module 2.0 is also available separately in our online dive shop.

Easy Installation and Stable Connection with up to Three Transmitters

Mounting the Mares cylinder pressure transmitter is straightforward: it is simply connected to an available compatible high-pressure port (7/16″) on your regulator. Pairing the transmitter with the Sirius dive computer is effortless and is stored permanently so that the connection remains even after a battery change or software update.

This Mares transmitter with LED provides a reliable radio connection to the dive computer and operates effectively within a radius of up to 1.5 m. The Mares Sirius can be paired with up to 3 transmitters simultaneously, allowing you to use multiple dive cylinders underwater.

Reliable Data Transmission for Enhanced Safety

Real-time information on your air consumption and cylinder pressure is transmitted directly and accurately to the dive computer via the radio connection. This valuable data feeds into all dive calculations, providing you with precise information about your no-decompression time, saturation, and remaining air time, for a safe dive.

Pressure Display via LED

Once the transmitter is activated (i.e. when pressure reaches the first stage of the regulator, not just at the beginning of the dive), the LED display of the Mares transmitter shows the approximate pressure of the breathing gas cylinder without you needing to look at the dive computer. The colour-coded LED allows you to visibly check your air supply at the surface. Underwater, it also enables your buddy or dive guide to see at a glance how much air is still in your cylinder.

Long Battery Life

The Mares Tank Module 2.0 uses a standard 14250 battery, which provides a operating time of approximately 150 hours, depending on the ambient temperature. The operating time of the transmitter begins when the tank is opened, not just at the actual dive. The current battery status is displayed on the dive computer when the transmitter and computer are used together.

Robust Construction for Maximum Durability

For secure operation, the Mares LED Tank Module 2.0 is made from highly resilient materials and complies with EU certification up to 300 bar according to EN250:2014.
