This function automatically re-
draws the chart according to the
boat’s course, to maintain 2/
3rds of the screen ahead of the
boat, provided that the boat’s
speed is greater than 3 knots.
This function will be activated
only if no waypoint has been pre-
viously inserted.
Overzoom
The Overzoom function allows
the chart scale to expand any-
where up to 1/4 NM. The
Overzoom does not provide any
additional chart detail, but im-
proves only the readability of the
existing information, thus acting
as a magnifying glass.
