Pros
  • Monitors up to 3 wireless transmitters for multi-tank or multi-diver setups
  • Watch, dive computer, and digital gauge modes in one unit
  • User-replaceable CR2430 battery rated for around 300 dive hours
Cons
  • Discontinued, Oceanic/Huish no longer sells it new and has moved to the OCi as its successor
  • No Bluetooth on the base unit, relies on USB for log downloads
  • Around $900 with a transmitter, pricier than newer air-integrated computers with color displays

The Atom 3.1 is a watch-style evolution of Oceanic’s long-running Atom line, built around the company’s dual-algorithm approach and support for up to three wireless tank transmitters. It has since been discontinued in favor of the OCi, so remaining stock is mostly old dealer inventory rather than fresh production.
