Point the black arrow on the upper side of your screen against a target and read the bearing. Select magnetic or true depending on whether you wish to read magnetic north or true north.
If you are moving you will get your COG (course over ground), and SOG (speed over ground). At a standstill, both COG and SOG will read ”zero”.
As the only additional function you can always read your position in latitude/longitude.
Keep in mind that your smartphone might need to calibrate. Adopt the habit to always start by moving your device in circles. To make sure that you are getting the correct data, always check with another compass, mechanical or other.
Due to limitations of smartphones you should never make important decisions based solely upon the smartphone compass.
We hope you will enjoy The Marine Compass and find it useful. Navigate carefully and stay safe!
