Sometimes the electronic compass will keep the map jumping around. If you hold down the page button you can turn it off and on as needed.

Do you still have to move a few feet to register? [/quote]

If the compass has been turned off the GPS will assume you are pointing the same direction as when you stopped movement. If the wind spins the canoe you will need to turn the compass back on or move a short distance for the GPS to reestablish direction of travel.
