The Liquivision Kaon:
Air & Nitrox Dive Computer

The Kaon is a wrist-mounted air and nitrox computer that offers superior readability thanks to our fully user-customizable color OLED display, which is angled towards the diver to convey information at-a-glance. Its intuitive patented tap-navigation system allows the diver to scroll up and down through clearly described menu options, and to easily update a user setting or make a selection. No more remembering complicated button-press sequences! Finally, it has a remarkably compact and ergonomic form-factor that makes it comfortable to wear even without a wetsuit!

It offers three dive modes:

- REC MODE allows 1 gas to be used, such as Air, Nx 32 or Nx36. This mode can quickly calculate your NDL and provide current saturation information between dives. It has the option to simulate the dive on the computer before getting in the water. There is a large and detailed logbook, which includes dive graphs of each dive.

- TEC MODE allows 3 gases to be used, including a bottom mix and up to two deco mixes. In addition to the REC MODE features, it provides more advanced dive planning functions. However, it is still far simpler to use than the XEO trimix computer.

- GAUGE MODE displays information such as depth and dive time. It also has a stopwatch and coneveniently enough the average depth is resettable.

All NDL and deco calculations in Tec and Rec mode are done based on the well-known and proven Buhlmann ZH-L16C algorithm* with deep stops and 3 levels of conservatism (based on Gradient Factors).


READABLE: The Kaon features a full color OLED screen, with an angled display, and huge fonts. The colors are fully user-configurable and the font shape and size was designed with input from physicians.

ERGONOMIC: The Kaon is compact and shaped to fit your wrist (male or female), with an angled screen to optimize readability. The unit is designed for ease of use whether you are using your bare hands or thick dry gloves.

INTUITIVE: The Kaon menus are easily navigated, and Liquivision’s patented tap-interface allows you to interact with the unit quickly and easily.

RELIABLE: The Kaon incorporates the proven Liquivision patent-pending ceramic pressure sensor technology. It is extremely rugged and CE rated to 200m (656ft)

CUSTOMIZABLE: The Kaon offers you the unique possibility to customize the display layout and colors for each piece of information on your screen, such as depth or time, so you can configure the display based on your individual needs and preferences.

SIMPLE TO MAINTAIN: The battery is user-changeable in one minute, with no tools or coins required – just finger-tighten. Also we offer disposable as well as rechargeable batteries.
