Targeting on the Cruising Screen
Use the
ROCKER
(GPSMAP 4000 series) or touch the target location (GPSMAP 5000 series) to
begin targeting. A green ring and a green line appear. The green ring corresponds with the range
rings to help define the distance of an object from your location. The green line corresponds with the
heading line to help define the bearing of an object from your location. As you move the
ROCKER
,
you adjust the point where the green ring and green line intersect. This point indicates your target.
As you move the target over objects on the radar, target options appear along the right side of the
screen.
