So which is better for sailing?
It is my understanding that
GPS only works while moving so the electronic
compass is more accurate at slower speeds or when standing still (a drifter), but the electronic
compass uses more
battery power than the
GPS function does.
When setting up the Compass function on the unit, what threshold speed do you set for the unit to switch from electronic compass to GPS and after how many minutes of slower than speed?
What is the
battery life for GPS vs. Electronic Compass?
