3.  DIVING WITH THE MOSQUITO

In order to familiarize yourself with the menu based 
functions, Suunto recommends you use your Quick 
Reference Guide supplied with the Mosquito together 
with the information in the following chapters. 

This section contains instructions on how to operate 
the dive computer and interpret its displays. You will 
fi nd that this dive computer is easy to use and read. 
Each display shows only the data relevant to that 
specifi c diving situation.

Chapter 3.1. Before Diving contains general 
instructions for all the dive computer modes. Chapter 
3.2. Scuba Diving information for air and enriched 
air nitrox scuba diving and Chapter 3.3. Free Mode 
information for freediving.
