CHART/SIDE COMBO VIEW
(987c SI Combo models only)
Chart/Side Combo View shows regular chart information and side imaging sonar
information 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
Navigation X-Press™ Menu: Active Side or Side Imaging 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 Navigation X-Press™ Menu:
Split Position or Side Imaging X-Press™ Menu: Split Position for more information).
NOTE: See Side Imaging View and Chart View for more information about each side of this view.
CHART ORIENTATION
(987c SI Combo models only)
All the chart views allow you to choose the orientation of the chart. When North-Up
orientation is selected, True North is shown at the top of the display. In other words,
objects located to the north of the boat are drawn above the boat. When Course-Up
orientation is selected, the direction of motion of the boat is shown at the top of the
display. In other words, objects ahead of the boat are drawn above the boat. In both
orientations, the view pans automatically, so that the boat is always centered on the
display. When the boat is stationary, it is drawn as a circle. When the boat is in motion,
it takes on a boat shape, pointed in the direction of motion (always Up in the Course-
Up orientation). See
Navigation Menu Tab: Chart Orientation for more information.
VIEWING CARTOGRAPHY
(987c SI Combo models only)
In the Chart or Combo Views, there are several cartography-related functions that you
can access using various keys.
Panning: Use the 4-WAY Cursor keys to move the chart around on the display in the
direction of the key being pressed. When you do this, a Bullseye Cursor is drawn at the
top of the screen and is linked to the boat by a yellow line, even if the boat is off the
screen. At the same time, a cursor dialog box is displayed at the top of the screen with
the distance and bearing from the boat to the cursor position and the
latitude/longitude coordinates of the cursor. When the cursor is active on the display,
you can also use the 4-WAY Cursor Control key to move the cursor diagonally.
