Suunto D4 is all about enjoying your diving experience. Lightweight, easy to use, and stylish, it’s a full-decompression computer with innovative freedive mode – the perfect companion on your next dive vacation.

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

Multi-mode versatility
In both Air and Nitrox mode, the clear, easy-to-read screen can display 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 increase your time underwater by adjusting the oxygen content of your gas between 21% and 50% and adjust your PO2 limit between 0.5 and 1.6 bar.

Dedicated Freedive mode
With its innovative freedive functions and dedicated freedive mode, Suunto D4 is also perfect if you're serious about breath-hold diving. Programmed to sample depth three times a second, Suunto D4 records highly accurate data on the true depth reached.

Flexible decompression
Using the Suunto Deep Stop RGBM algorithm, Suunto D4 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. When the dive is over, use optional Suunto Dive Manager PC software to transfer your dive data to your computer for further analysis and to maintain a detailed logbook featuring graphical representation of all your dives.

Add a splash of color to your dive
Mix and match your look with the new Suunto D4 dive computer straps. The new colorful selection of straps include blue, yellow, pink, or black – your choice when you purchase your dive computer or available as individual accessories. Suunto D4 is also available with a white body and strap
