The Liquivision Xen bottom timer:
Free Your Mind.
At last, bright color OLED display technology is available in an affordable computer built by a top freediver for freedivers!
XEN FREEDIVING FEATURES
Ultra-Readable Display
The light-emitting display with a 170 degree viewing angle means that you can read your computer when your arms are extended – without breaking your streamline! No more need to bring your arm next to your face, or to press the backlight activation button.
The OLED is readable in all conditions: in total darkness at 100m or in poor visibility at 10m. The display is set at an angle on your wrist for easy viewing. Also, the color of each piece of information on the screen is individually customizable, offering you the option to color-code key data (like depth or time) for instant recognition. Finally, you can choose among three different display layouts, adjusting the unit to your needs.
The easy access to your depth and dive time information allows you to ‘free your mind’ and concentrate on relaxing, equalizing, catching fish, or just enjoying yourself.
Intuitive Tap-Based Navigation
The Xen uses Liquivision’s innovative tap-based interaction, which makes extremely easy to navigate through menus and select your dive settings. No more need to memorize complicated button-push sequences to access the information you need!
Designed by a Top Freediver
The Xen is designed by Eric Fattah, former World Record holder, current North American Constant Weight record holder and author of the Frenzel-Fattah equalization technique. Unlike most dive computer companies, that simply add a freediving mode to a scuba computer, Liquivision started with freediving in mind when it built the original F1 in 2005. The Xen takes everything we’ve learned about dive computers, packs tons of relevant freediving features, and delivers them in an affordable package.
Dive Logging & Graphing
The Liquivision Xen can sample and log depth four times per second, allowing ultra precise graphing of dives - precise enough to see every stroke when diving without fins, and often precise enough to see every monofin stroke as well. Dive graphs are visible in high resolution directly on the unit or can be downloaded onto your PC or Mac for further analysis. This is important information to track your dive and training progress.
The Xen offers a huge dive log memory, about 4200 freedives at 1 sample per second or 1050 freedives at 4 samples per second (assuming 2 minutes per dive).
Decompression Warnings
Decompression illness is a risk with repetitive long or deep dives, or with fast ascents. The Liquivision Xen is the first freediving computer ever to incorporate a decompression warning based on the ascent rate. The decompression ascent rate limit is not a constant speed, but rather a constant derivative, using Eric Fattah’s pioneering work on freediving ascent rate limits. The user can select a standard ascent rate limit (5% per second), or a more conservative 4% per second, or a very conservative 3% per second. If the diver violates the ascent rate, a warning is displayed during the surface interval, indicating a decompression danger. This tells the freediver that s/he should cease doing any further deep dives, and consider preventative measures such as a shallow recompression dive on air or pure oxygen.
User-Changeable Battery
The Liquivision Xen uses a lithium battery that is easily changed by the user in seconds. It also has a “hot-swap” feature that allows the unit to remain on for several seconds as the battery is being changed. This means that user settings, date and time of day are not lost during battery changes.
Resettable Stopwatch
The Xen also incorporates a resettable stopwatch to time static breath holds or warm-ups.
