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

7.1 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.
