Description:

Diving is about freedom, adventure, and sharing your experiences. That's why, in addition to its existing dedicated freedive mode, the Suunto D4i now features optional wireless air integration. Easy synching with Movescount lets you share your unforgettable dives ¡V and images and video ¡V with the world as soon as you're out of the water.

Hassle-free tank pressure monitoring
The D4i includes optional wireless air integration for easy monitoring of your tank pressure, so you can keep track of current cylinder pressure and remaining air time with a quick glance at your wrist, giving you more time to enjoy your dive.

Share your diving experiences with the world
Using DM4 with Movescount software on your laptop, you can easily synch your Suunto D4i with the Movescount.com online community, where you can store and share your dive data, images, and more. With Movescount, you can also share tips on cool dive spots and connect with other divers from all over the world.

Effortless operation
The easy-to-read dot matrix display and electro-luminescent backlight mean your dive-critical information ¡V including depth, dive time, and decompression status ¡V will all be shown clearly.

Multi-mode versatility
In both Air and Nitrox mode, the clear, easy-to-read screen displays your current and maximum depth, current time, dive time, decompression time, and temperature. Audible and visual depth and time alarms warn you when it¡¦s time to start your ascent. In Nitrox mode, you can maximize your dive time by adjusting the oxygen content of your gas between 21% and 50% and your PO2 limit between 0.5 and 1.6 bar.

Dedicated freedive mode
With its innovative freedive functions and dedicated Freedive mode, Suunto D4i is also perfect if you're serious about breath-hold diving. Programmed to sample depth three times a second, Suunto D4i records highly accurate data on the true depth reached.

Flexible decompression
Using the Suunto Deep Stop RGBM algorithm, Suunto D4i enables continuous decompression for optimal ascent time. For deeper dives, the Deep Stop option adds further protection with a series of deep stops between your maximum depth and ceiling.

Plan and review
You can test upcoming dives and view no-decompression time data for different depths before getting in the water with the built-in dive planner. After your dive, you can easily transfer your dive data to your computer for further analysis using the optional Suunto DM4 software, which includes a detailed logbook featuring a graphical representation of all your dives.
