The Dive360 Take

The Sirius L suits divers who want a computer that feels more like a watch on the wrist. Its clear LCD and two-button controls keep the layout straightforward, while air, nitrox and freedive modes make it useful across different days on the water.

The user-replaceable battery is a practical detail for travel, and Bluetooth makes it easier to keep your dive logs together without adding another cable to the holiday packing list. It is the direction we would look when compact size and everyday convenience matter more than having a colour screen and wireless tank-pressure display.

The serious stuff
  • Bühlmann ZH-L16C algorithm with adjustable gradient factors.
  • Air, nitrox, bottom timer and freedive modes; up to three air/nitrox mixes.
  • 33 mm diameter segment LCD with mineral glass and backlight.
  • Two-button navigation.
  • Bluetooth for log downloads and firmware updates through the Mares or MySSI app.
  • User-replaceable CR2450 battery; duration depends on backlight use and water temperature.
  • Safety Stop+ provides an optional extended-stop function.
  • Bottom timer with resettable average depth and stopwatch; decompression planner.
  • Watch functions include time, date, alarm and countdown timer.
  • Cylinder pressure is read from a separate gauge; no wireless air integration.
Why we like it

It keeps the wrist footprint manageable while still providing adjustable gradient factors and up to three nitrox gases.

The combination of a replaceable battery and app connectivity is practical for dive trips. One fewer charging cable is a small victory in a bag already full of them.

Who we recommend it to

Recreational scuba divers and freedivers who want a compact, lightweight computer with a clear LCD, simple controls and Bluetooth log transfer. A useful choice for divers who prefer replaceable batteries to regular charging.
