Suunto EON Core
1. Take off your Suunto EON Core.
2. Keep the middle button pressed to enter the menu.
3. Browse to General » Compass.
4. Press the middle button to enter Compass.
5. Scroll up or down to select Calibrate.
6. Start calibrating the device by trying to move it around the xyz axels of the coordinate
system (like you were drawing a small circle) so that the magnetic field is as stable as
possible during the calibration. To achieve this, try to keep Suunto EON Core in the same
location and do not move it around using large movements.
7. Repeat the rotation as long as the compass calibration is successful.
8. A sound indicates when the calibration succeeded, and the screen goes back to Compass
menu.
NOTE: If the calibration fails several times in a row, you may be in an area with strong
sources of magnetism, such as large metal objects. Move to another location and try to
calibrate the compass again.

You should always adjust your compass declination for the area where you are diving to get

5. Scroll up/down to set the angle of declination: Starting from 0.0º scroll up towards East or
down towards West declination. To turn declination off, set declination angle to 0.0º.
6. Press middle button to save changes and go back to the Compass menu.
7. Keep the middle button pressed to exit.

3.8.3. Locking the bearing

A bearing is the angle between north and your target. In simple terms, it is the direction you
want to travel. Your heading, on the other hand, is your actual direction of travel.
You can set a bearing lock to help you orientate yourself underwater and ensure you maintain
your direction of travel. For example, you can set a bearing lock for the direction to the reef
before leaving the boat.
You can reset the bearing lock at any time, but you can only clear a bearing lock while at the
surface.
