The available depth units are metres or feet. These units are toggled
with the depth or speed key.
The available speed and log units are Kmh, Mph, Kts, SM and NM.
These units are toggled with the depth or speed key.

The correction factor = Charted distance ÷ Average Distance.
The charted distance is the distance between two charted objects.
Ideally, this should be about 1 nm.
