sector just above the horizon. Then, shift your gaze
upward about 10°, and search back to the starting point.
Repeat this process until the zenith is reached; then rest
your eyes for a few seconds before starting over.
When searching at night, keep your eyes moving.
Try to adhere to (stay with) the sector scan (and upward
shift) even though the horizon may not be visible. If you
spot a target (or even think you have), don’t stare at it.
Instead, look slightly to either side.
REPORTS
Every object sighted should be reported, no matter
how insignificant it may seem to you. The initial report
consists of two basic parts—what you see and its
bearing (direction) from the ship. Aircraft sighting
reports also include altitude (position angle). Report the
contact as soon as you see it, then follow with an
amplifying report. Include the object’s identity
(destroyer, periscope, log, and so on) and direction of
travel (closing, crossing, and so on). Refer to the ships
SOP on reporting procedures.
