Tips for measuring the bearing
• 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.
Target on collision course with your
vessel?
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.
