Targeting on the cruising screen

Use the

ROCKER

while viewing the cruising screen 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.

Create Waypoint—marks a waypoint at the targeted object or location.
Acquire Target—assigns a MARPA (Mini Automatic Radar Plotting Aid) tag to the targeted object.

NOTE: MARPA requires the use of a heading sensor. The heading sensor must output the NMEA 0183

sentence HDM or HDG.

MARPA Target (only appears when you are targeting a tagged MARPA object)—opens the

MARPA target information window. Remove MARPA objects from this window.
