Aeris A300 CS


In 1983 the DecoBrain, became the first decompression diving computer, capable of displaying the information that today’s diving computers do.  Interestingly in 1983 I was working at ICl in Melbourne where they were working on colour monitors for Personal Computers.  The Aeris A300 CS computer has melded these 2 technologies with Bluetooth technology creating an experience that was simpler, more useful, and more enjoyable Dive Computers.

With an easy-to-use interface, amazing readability, powerful features, and simplicity at its core, the A300 CS is the new benchmark for modern dive computer design. The Aeris A300 CS is engineered to take full advantage of Bluetooth technologies, interacting with your dive computer before and after the dive couldn’t be any easier

The Aeris A300 CS has a completely new structure, applied across the whole system that brings clarity to the entire experience. The displays and interface unobtrusive with clutter stripped away and unnecessary data and icons removed. In taking away elements that don’t add value, there’s greater focus on what matters most… the diving. It’s about showing the diver what you need to see when you want to see it.


The Aeris A300 CS is a feature-rich dive computer that you can pick up for the first time and already know how to use it. A hoseless, air-integrated computer with patented air time remaining algorithm. High contrast OLED color screen, tilt compensated 3-axis digital compass, Bluetooth ready, up to 4 nitrox mixes, user replaceable battery, and an intuitive push button menu system.

The DiverLog for iOS App  makes it even easier to setup your dive computer and lets you do more after the dive than ever before.

The future of personal dive computers powered by OLED color display and Bluetooth technology has arrived in the form of the Aeris A300 CS Dive Computer.
