Figure 42: Sector Coverage
5.5.4 Sector Rotate
The Sonic 2024/2022 has the capability to direct the selected sector to either port or starboard,
allowing the user to map vertical features, or areas of interest, with a high concentration of
soundings resulting from the compressed sector.
First, change the sector coverage to the desired opening angle; this will concentrate the 256 beams
within the sector, and then increase the Range setting.
Second, rotate the swath towards the feature to be mapped with high definition. This is done on
the fly, with no need to stop data recording or to go off line. When rotating, make sure to keep the
bottom detections within the confines of the range.

The Sector Coverage can also be controlled via
the mouse cursor, inside the wedge display.
Position the cursor on either of the straight sides
of the wedge; the cursor will change to a double
arrow and the sector can be reduced or
increased. When using the cursor to change the
sector coverage, the change only takes place
when the mouse button is released.
The sector angle will be numerically visible in the
lower left hand corner of the wedge display
while the mouse button is depressed.
The sector can also be rotated using the mouse cursor, in
the wedge display. Position the cursor on the curved
bottom of the wedge; the cursor will change to a
horizontal double arrow, the wedge can now be rotated to
port or starboard. The angle of rotation is numerically
visible in the lower left hand corner of the wedge display
during rotation. A clockwise rotation is positive, an anti-
clockwise rotation is negative.
The change only takes place when the mouse button is
released. To return to a 0 rotation, use the Hotkey Alt+Z.
