COMES WITH A 5 YEAR AUSTRALIAN WARRENTY
Suunto D4 Wristop Dive Computer

Suunto D4 is a full-decompression wristop dive computer
designed to put information, ease of use, and style first.
Its four operating modes, dive planning and analysis
functions, and compatibility with optional
Suunto Dive Manager PC software make Suunto D4 a great choice
for those who value functionality and ease of use.
Suunto D4 comes with a scratch guard that helps to
protect the display against scratching.

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. Surface time and depth alarms help you
make responsible decisions both in and out of the water.

In both Air and Nitrox mode, the clear, easy-to-read screen
can display your current and maximum depth;
current time, dive time, and 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.

Like other advanced Suunto dive computers, Suunto D4 uses the
Suunto RGBM algorithm for decompression calculations.
It also allows you to choose between taking traditional safety stops
or, with the Deep Stops feature activated,
taking your safety stops at depth. Before diving, the no-stop-time
planner helps you prepare for your dive.
Enter the planned maximum depth of your dive, and Suunto D4 will tell you
how long you can dive before needing
a decompression stop. After diving you can instantly review all the data in
the logbook. Suunto D4 is also compatible
with the optional Suunto Dive manager PC software, which provides
more in-depth analysis and graphical
representation of all your dives.
