What our customers are saying about Mares Sirius dive computer

This Mares dive computer offers a bright, clear display with good underwater visibility, even in darker conditions with its backlight. Buyers praise its quality and value. The watch-style design is a strong competitor to other brands. It seamlessly integrates with the SSI app, and for full functionality, consider the LED Tank Module 2.0 transmitter

Very good value and features overall

Shoan

Battery can last at least 20plus dives one 1 charge. If used as a watch, at least 1 week. Loved the displays and graphics that things like remaining pressure, dive profile, nitrogen accumulation. Overall a very solid dependable air integrated dive comp that doubles as a regular watch.

awesome

Despite some comments about poor underwater visibility, the purchase turned out to be excellent. The Mares Sirius has good visibility while diving; only when it's really dark can you turn on the backlight and it's fine. I recommend purchasing the LED Tank Module 2.0 transmitter, which gives you full access to the computer's functions. It integrates seamlessly with the SSI app. If you need a watch-style dive computer at a good price, I recommend it.
