BIRD’S EYE VIEW (987c SI Combo models only)
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.
CHART/BIRD’S EYE COMBO VIEW (987c SI Combo models only)
Chart/Bird’s Eye Combo View shows both the Chart and Bird’s Eye views in a
combination split screen. You can perform any of the functions for either of these
views, but only when the view you want to control is selected as the active side
(see Sonar X-Press™ Menu: Active Side or Navigation X-Press™ Menu: Active Side for
more information). A green arrow points to the side that is active. You can also
adjust the size of the left side of a split screen (see Sonar X-Press™ Menu: Split
Position or Navigation X-Press™ Menu: Split Position for more information).
NOTE: See Bird’s Eye View and Chart View for more information about each side of this view.
