• Bearing measurements of smaller targets

are more accurate; the center of larger tar-
get echoes is not as easily identified.

• Bearings of stationary or slower moving

targets are more accurate than bearings
of faster moving targets.

• To minimize bearing errors keep echoes

in the outer half of the picture by chang-
ing the range scale; angular difference be-
comes difficult to resolve as a target
approaches the center of the display.

You can determine if a target might be
on a collision course with your vessel by
placing the EBL on the target. If it tracks
along the EBL as it approaches the
screen center it may be on a collision
course with your vessel.

The menu, consisting of 6 sub menus, mostly

ment. To open or close the menu, press the
