North Reference
‘Reference’ refers to the orientation of a map’s grid.
Map makers try to align the vertical lines on a map
with
‘True North’
. True North is the direction from any
location on the earth’s surface to the “North Pole”. Maps
are typically referenced to true north. Because a compass
points to magnetic north, not true north, maps indicate
the difference between true and magnetic north with
something called ‘variation’ or ‘declination’.
The eTrex Summit can be set to
disable the Electronic Compass
above a user selected speed.
This helps to conserve battery
power.
Set a time delay before switching
to the electronic compass when
moving at a speed slower than
the user-selectable speed.
