1. INTRODUCTION
Congratulations on your purchase of the SUUNTO D3 wristop freediving computer. The D3 builds on the Suunto tradition of delivering feature-rich dive computers, providing different operating modes for different types of diving. Push
button controls access a wide selection of choices. The display is optimized for the
dive mode chosen and it incorporates a patented user defi nable display fi eld. This
freediving computer is a compact and sophisticated multipurpose dive instrument,
designed to give you years of trouble-free usage.
CHOICE OF DIVING AND WATCH MODES
User options for the D3 are selected using the push buttons.
Pre dive confi guration and setup options include:
• Choice of operating mode – Gauge diving/ Freediving
• Maximum depth alarm
• Dive time alarm
• Choice of unit – Metric / Imperial
• Clock, calendar, daily alarm, stopwatch, downtimer, dual time
• User defi nable display fi elds
1.1. SAFETY PRECAUTIONS
Do not attempt to use D3 without reading this instruction manual in its entirety,
including all the warnings. Make sure that you fully understand the use, displays
8
and limitations of the instrument. If you have any questions about the manual
or the freediving computer, contact your SUUNTO dealer before diving with
the D3.
Always remember that you are responsible for your own safety.
When used properly, this freediving computer is an outstanding tool for assisting
properly trained, certifi ed divers in planning and executing sport dives. It is not
a substitute for certifi ed scuba instruction or freediving training.
1.1.1. EMERGENCY ASCENTS
In the unlikely event that D3 malfunctions during a dive, follow the emergency
procedures provided by your certifi ed dive training agency or, alternatively,
STEP 1: Assess the situation calmly and then move promptly to less than 18 m
STEP 2: At 18 m [60 ft], slow down your ascent rate to 10 m/min [33 ft/min]
STEP 3: Stay there as long as you assess your air supply will safely allow. After
[60 ft].
and move to a depth between 3 and 6 meters [10 to 20 ft].
reaching the surface stay out of the water for at least 24 hours.
1.1.2. FREEDIVING
Freediving, and particularly freediving in combination with scuba diving, may
have risks that have not been researched and are not commonly known.
9
Any person who engages in any form of breathhold diving is in danger of shallowwater blackout (SWB) i.e. the sudden loss of consciousness caused by oxygen
starvation.
Any breathhold diving results in some nitrogen build-up in the blood and other
fast tissues. Due to the short time spent at depth this build-up is generally not
signifi cant. Therefore, provided the effort involved in freediving has not been
severe, there is little risk in diving after breathhold diving. However, the converse
is more unknown and may increase signifi cantly the risk of DCI. Therefore,
FREEDIVING AFTER SCUBA DIVING IS NOT RECOMMENDED. You
should avoid freediving and not exceed fi ve meters [16 ft] for at least two hours
after scuba diving.
Suunto also recommends you to be trained in freediving technique and physiology before conducting breathhold dives. No dive computer can replace the need
for proper dive training. Insuffi cient or improper training may cause a diver to
commit errors that may lead to serious injury or death.

2.3. WATER CONTACTS
The D3 is automatically activated when sub merged
in water. This function is made possible by the use
of water contacts. The water contacts consist of the
PC-interface poles and the four push-buttons of the
D3 (Fig. 2.2). When the PC-interface poles and one
of the push-buttons are connected by the conductivity
of the water the Surface or Diving Mode is automatically activated.
Contamination or dirt on the PC-interface poles may
prevent this automatic operation. It is, there fore, important that the poles are kept clean. The poles can
be cleaned with fresh water and a soft brush (e.g.
tooth brush).
NOTE: Water or moisture build-up around the water contacts may cause the contact to activate automatically. This can happen, e.g., when washing your
hands or sweating. If the water contact activates in
the Time Mode, an AC text will appear on display
(Fig. 2.3.), and it will be shown until the water contact
deactivates, or the D3 enters the Dive Mode automatically. To save the battery power, you should deactivate the water contact by cleaning it and/or drying
it with a soft towel.
