7 USING ALTI & BARO MODE

In the ALTI & BARO mode you can view the current altitude,

barometric pressure or snorkeling depth. It offers four profiles:

AUTOMATIC, ALTIMETER, BAROMETER and DEPTH METER (see

7.2.2 Setting profiles ). You can access different views depending on

which profile is activated when you are in the ALTI & BARO mode.

7.1 How Alti & Baro works

To get the right readings from ALTI & BARO, it is important to

understand how Suunto Essential calculates altitude and sea level

air pressure.

Suunto Essential constantly measures absolute air pressure. Based

on this measurement and reference values, it calculates altitude or

sea level air pressure.

CAUTION: Keep area around sensor free of dirt and sand. Never

insert any objects into the sensor openings.
