7. Using ALTI & BARO mode
In the ALTI & BARO mode you can view the current altitude, barometric pressure or
snorkeling depth. It oers four profiles: AUTOMATIC, ALTIMETER, BAROMETER and DEPTH
METER (see 7.2.2. Setting profiles). You can access dierent 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 Core
calculates altitude and sea level air pressure.
Suunto Core 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.
7.1.1. Getting correct readings
If you are engaged in an outdoor activity that requires you to know the air pressure, you need
to enter the altitude reference value for your location. This is found on most topographic
maps. Your Suunto Core will now give you the correct readings.
To get the correct altitude readings, you need to enter the sea level air pressure reference
value. The sea level air pressure reference value relevant to your location can be found in the
weather section of the local newspaper or on the websites of national weather services.
Absolute air pressure is measured constantly Absolute air pressure + altitude reference = Sea
level air pressure
* Absolute air pressure + sea level air pressure reference = Altitude *
Changes in local weather conditions will
aect altitude readings. If local weather changes
often, it is advisable to reset the current altitude reference value frequently, preferably before
starting your journey when the reference values are available. If local weather is stable, you
do not need to set reference values.
7.1.2. Getting incorrect readings

profile + standing still + weather change
If your ALTIMETER profile is on for an extended period of time with the device in a fixed
location while the local weather changes, the device will give incorrect altitude readings.
