The Mares Sirius Dive Computer in Black/Black is a reliable and durable instrument for scuba and diving enthusiasts. Its long-lasting battery provides up to 30 hours of dive time on a full charge, helping you plan longer underwater sessions. The high-contrast MIP color display offers clear visibility, and Bluetooth connectivity enables direct pairing with your smartphone. It can store 100 dive logbooks, making it a practical piece of diving gear for tracking performance. The sleek design is comfortable to wear in and out of the water. Transmitter sold separately.
Designed for versatile scuba and technical diving, Sirius uses the ZH-L16C algorithm with gradient factors and predictive multigas. It is Nitrox and Trimix capable, supporting up to five gases. The device features a MIP color high-resolution display, a full tilt digital compass with bearing memory and stopwatch, hoseless tank data integration for up to five transmitters, and color-coded tank pressure for at-a-glance readability. Additional modes include bottom timer with resettable average depth and stopwatch, a decompression dive planner with a surface interval function, and a 100-dive logbook with multiple graphs. It also provides tissue saturation and dive profile graphs, an underwater menu for in-dive settings, future deco and runaway deco alarms, two dive data display options, and three watch faces with color choices. Battery management offers up to 30 hours of dive time per full charge without tank data integration (20 hours with integration). Bluetooth enables direct connection to a smartphone. Transmitter sold separately.

Frequently Asked Questions
Why do I need my own dive computer?
A dive computer tracks the actual depth and time profile you have dived and the tissue loading that follows from it, which is personal to you. A rented computer has no record of your recent diving, and swapping models each trip means relearning the display and menus when you should be focused on the dive. Owning one you know well is a genuine safety and comfort improvement.
Can two divers share one dive computer?
No. A computer only tracks the profile of the diver actually wearing it, and even buddies who stay together do not follow identical depth and time profiles. Every diver needs their own computer, and passing one between divers or between dives is unsafe.
What does conservatism mean on a dive computer?
Conservatism settings make the computer's calculations more cautious, shortening allowed bottom times and adding margin beyond the base algorithm. Divers commonly add conservatism for factors such as cold, hard work, fatigue, or repetitive multi-day diving. How and when to adjust it is covered by your training and your computer's manual, so set it before you get in the water and follow what your computer tells you during the dive.
What kind of battery does a dive computer use?
Broadly there are two types: user-replaceable batteries, often a coin cell that you or a shop swap along with resealing an o-ring, and sealed rechargeable batteries that charge from a cable or dock. Neither is universally better, as replaceable cells are convenient on remote trips while rechargeables avoid ever opening the case. Follow the manual exactly for any battery change, because an improperly seated o-ring or case is the usual cause of a flooded computer.
Do I need to do anything special for altitude diving or flying after diving?
Yes, both change the picture, and both are governed by your training agency's guidance and your computer's instructions rather than any casual rule of thumb. Many computers have an altitude setting that must be configured before diving at elevation, and most display a no-fly or surface-interval countdown after a dive. Follow your computer and your training, and ask a dive professional or a dive-medicine specialist if you are unsure.
How do I care for a dive computer?
Rinse it in fresh water after every dive day, paying attention to the buttons and around any sensor openings where salt crystals form, and let it dry fully before storing. Keep it out of prolonged direct sun and extreme heat, and avoid pressing buttons while sand is on the case. Inspect the strap or bungee often, because a failed strap loses far more computers than a failed computer does.
What is the difference between wrist, console, and air-integrated dive computers?
A wrist computer is worn like a watch and read by raising your arm, while a console computer sits at the end of a hose with your other gauges. Air integration means the computer also displays cylinder pressure, either through a hose or from a wireless transmitter on the first stage, and often estimates remaining gas time. All of them run a decompression algorithm, so the real difference is where you read the information and how much of it you get.
