Ready, Set, Dive.

The A300 CS project started with a desire to create an experience that was simpler, more useful, and more enjoyable -- while building on the things people already love about AERIS Dive Computers.

It has a completely new structure, applied across the whole system that brings clarity to the entire experience. The displays and interface are purposely unobtrusive. Clutter has been stripped away. Unnecessary data and icons have been removed. In taking away elements that don't add value, there's greater focus on what matters most... your dive. It's about showing you what you need to see when you want to see it. That's it. Simple.

When we can produce such a powerful, feature-rich dive computer that you can pick up for the first time and already know how to use it, we've done our job.

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 A300 CS is engineered to take full advantage of Bluetooth 4.0 LE* technologies, interacting with your dive computer before and after the dive couldn't be any easier.  *Bluetooth 4.0 LE dongle may be required.

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:

  • Get full remote control of all Dive Computer Settings.
  • View Log and Profile data, add location, notes and other details.
  • Share your favorites via email, Facebook(R) and more.
  • Wirelessly update your A300 CS firmware on the go for the latest features and best performance.

AERIS Computer Interface (ACI) for PC is available now .

* DiverLog for Mac A300 CS compatibility is scheduled for release June 15, 2014.

* DiverLog for iOS compatible with the A300 CS is scheduled for August, 2014. 

* DiverLog for Android is currently scheduled for December, 2014 availability.

    • **  Battery life varies depending on several factors including display intensity setting (user adjustable on surface and underwater), water temperature and age of the battery. Use may be extended by manually dimming the display underwater or activating Auto-Dim (light sensor) feature.

      Estimated use life: 25 hours of typical average operation; 15 hours at 100% brightness; 45 hours at 10% brightness; 3 hours when a low battery warning condition occurs (during which brightness is held to 30% maximum).

I have an Oceanic Atom 3.1 and picked up the A 300 CS mainly for diving in darker environments ie., Bonne Terre Mine, hot springs, lakes and some wrecks. I found I don't like hitting the glow button on the Atom 3.1 all the time and putting more drain on the battery. Plus doing this while ascending trying to read your watch is a pain. I will keep the Atom 3.1 for sunny warm water Caribbean dives but love the Aeris A 300 CS and will use it every where else. It's nice I can keep the same transmitter set up for both. Navigating the A 300CS is a breeze. I was a little reluctant to buy a very new product due to bugs but I've kept the most current firmware update and it's been great. The compass actually works and that's saying a lot for electronic compasses that I never really have had much luck with. I would recommend this product, good job Aeris.
I just switched from an Oceanic Pro Plus 3 to the A300 CS OLED as my primary computer. This was a very large leap going from hose to hose less connection. I'm very happy to say that I made the right decision. I still use the Pro Plus 3 as back up but the A300 CS OLED is much easier to read at depth and navigation through the screens are very easy and self explanatory which meant a very short learning curve. I highly recommend the A300 CS OLED
I flooded my old console Oceanic ProPlus and needed a computer in one week. I looked at the reviews and this one was highly rated. Appears to be the complete package. Has lots of information and more. The brightness must be on 100% in order for me to see the blue 3 minute safety stop countdown. It appears I will have to go to You Tube to see the video tutorial. And I haven't quite figured out how to download my data yet. Overall I am satisfied.
I have been diving an Atomic Cobalt/Oceanic VT 4.1 combo. Cold murky waters made it difficult to see my display on the VT 4.1. Then I could rely on my color Cobalt screen. Now I have the best of both worlds. It seems to have same menu as VT 4.1 but easy screen to read. I will still probably dive redundant computers still but will no longer need to look at Cobalt which is why any of us dive hoseless wrist mounts anyway. Love the fact that the computer is ergonomically designed to stay on side of wrist. This was a constant problem of my VT 4.1. Great job Aeris
Got the new a300cs and love it. I went from the the xr1, to the a300 wrist and now the cs. All the aeris computer are simple to use and have every function you could need......now with a nice oled screen. It's a must have.

*Battery life varies depending on several factors including display intensity setting (user adjustable on surface and underwater), water temperature and age of the battery. Use may be extended by dimming the display underwater.

** AERIS Dive Computers have user selectable Sampling Rates that determine when data is sampled and stored for subsequent download to associated PC interface programs. More frequent sampling provides more data per dive yet results in storage of fewer dives for download. Use with Air or Nitrox, with or without air integration, dive profiles, Free Diving activities, and other variables may also affect the number of dives that can be stored.
