Regarding the battery question, I saw the answer that was given here that ATMOS battery can’t be replaced,so it’s mean That when the battery dies I can throw the computer to the garbage? Thanks

No, you can have that computer sent to the factory for replacement.

I am an infrequent diver and I trying to justify something more than a Mares Puck. Even though rechargeable, batteries go bad over time and I would like to get more than a handful of dives out of it. Can the rechargeable battery be replaced after it has gone bad years in the future?

01/12/2023 Answered by Divers Supply

The Atmos Mission 2 diving computer's battery cannot be replaced. And all other rechargeable diving computers are the same as well.

What’s the difference between the Atmos M2 WG and the BG?

11/30/2022

11/30/2022 Answered by Divers Supply

Thanks for your questions about the Atmos Mission 2 Dive Computer. WG is the white band with gold bezel and the BG is the black band with gold bezel.

Is this air integrated?

Nice Dive Computer At A Good Price

By David Rohn on December 03, 2024 Verified Buyer

Good simple interface with the right information on screen during the dive. The color and vibration is great for warning or alarm. Bright enough under water. The phone app is disappointing. Won't use the other sports functionality.

Thank you for the great review on the Atmos Mission 2

Love This Product. Researched Many Dive Computers And This Is The Best One For The Price.

By Kenneth Wehmeyer on March 11, 2025 Verified Buyer

Not too big for casual wear but big enough to be easily readable with all the needed information when diving. Combines all the diving information along with a digital compass.

Thank you for the outstanding feedback
