Compass Mode
In compass mode, the device displays either true heading or magnetic heading at an update rate of 2Hz
(twice a second). True heading is the direction you are moving referenced to true north. Magnetic
heading is the degrees you are heading in reference to the local magnetic north. Magnetic heading is
calculated by offsetting the True Heading by the user defined
local magnetic declination
. The SC-1
displays heading only when your speed is greater than 1 knot, otherwise it will show a heading of 0
degrees, regardless of which direction you are actually moving.
The difference of the SC-1 to a conventional magnetic compass is that the SC-1 measures the direction
the device is moving in rather than the direction it is pointed in.
A major benefit of the SC-1 over a conventional magnetic compass is that it will give you accurate
heading information, regardless of the orientation in which it is mounted on your boat. SC-1's compass
reading depends only on the direction you are moving, not the direction the device is pointing.
The following figure shows both the upper and lower displays in compass mode, showing a heading of
226 degrees true:
In compass mode, the plus and minus buttons can be used to change the
display damping
for all the
modes.
