6-BEAM SONAR VIEW
6-Beam Sonar View displays information from each of the six 455 kHz beams in a
traditional 2D representation. This view displays the raw sonar returns from each
of the beams that are used to create the 3-dimensional wire frame representation
of the bottom in the 3D Sonar View. The 6-Beam Sonar View can be used for
identifying structure on the bottom and sonar returns in the water column. The
6-Beam Sonar View also provides information on sonar targets relative to the boat.
The far right window displays sonar targets which are to the far right of the boat
and the far left window displays sonar targets which are to the far left of the boat.
The remaining windows display sonar targets which are successively closer to the
boat. The width of coverage is approximately equal to the current depth.
BIRD’S EYE VIEW
Bird's Eye View shows a 3D perspective view of the track and the chart land contour
from a point above and behind the boat (the eye point). As the boat turns, the eye
point moves to follow the boat. Big Digits on this view provide digital data in a large,
easy-to-see format.
When you press the 4-WAY Cursor key in the Bird’s Eye View, the position of the eye point
will shift. This allows you to move and turn the eye point so that you can look off to the
sides, or even behind the boat. Pressing the RIGHT or LEFT arrow keys on the 4-WAY
Cursor key turns the eye point right or left, while pressing the UP arrow key moves the
eye point forward, and pressing the DOWN arrow key moves the eye point backward.
Pressing the EXIT key moves the eye point back to its original position behind and
above the boat.
