Introduction
Congratulations on the purchase of your Monitor 3 Air dive computer. Our designers have condensed important dive planning information into a
As with all diving equipment, it is important to understand the features and functions of the Monitor 3 Air. Before using the Monitor 3 Air, it is essential to read this manual in its entirety. Contained within this easy to read manual are illustrations to aid you in the complete understanding of the computer.
Section 1 instructs you on preparing the Monitor 3 for its first use. Section 2 explains all the functions and screen displays while on a dive. Section 3 shows you how to recall the dive memory. Instructions on planning a future dive are given in Section 4. Care & Maintenance tips are covered in Section 5. Lastly, the reference section contains the technical specifications and a description of the algorithm.

What is a “Dive Computer”
DEFINITION OF COMPARTMENTS
A dive computer is an instrument that mathematically simulates the absorption and release of nitrogen by hypothetical tissue types in the human body. These hypothetical tissues are commonly referred to as “compart- ments.” Each compartment absorbs and releases nitrogen at different rates. The Monitor 3 Air tracks these compart- ments constantly, providing you with
MULTI-LEVEL DIVING
If you use, or have used, dive tables you know the total amount of time you can stay under water is based on the maximum depth reached during the dive. Dive tables, such as the U.S. Navy dive tables, assume that you immediately descend to a single depth, stay at that depth for the duration of the dive, then immediately surface from that depth. This type of dive profile is referred to as a rectangu- lar dive profile (figure 1). In reality, however, most recre- ational divers go to the deepest depth first and make a gradual ascent to the surface. This type of dive profile is referred to as a multilevel dive profile (figure 2).
