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
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?
