Furuno SEARCHLIGHT SONAR CH-250 - Manual (Page 3)

The vertical sounder
displays how the depth
and bottom hardness are
changing ahead of own
ship. When the
soundome tilt is set to 90
degrees, the picture is the
same as a vertical sounder. It displays fish schools
and seabed conditions directly under the vessel.
Own ship track is monitored
with respect to the sonar
sounding area. Unrivaled
feature for purse seining.

VERTICAL SOUNDER
FULL CIRCLE with
VideoPlotter
A unique feature
of this sonar is the
mode integrating
the two images
shown to the left.
This sonar image also can be switched to a Half
Circle with Vertical scan.
FULL CIRCLE SCAN
The full circle scan
helps to detect fish
schools at any
bearing, all around
the vessel.
VERTICAL SCAN
The vertical scan paints
the bottom profile within a
user-specified vertical
plane.
The cursor indicator
reads slant range and
soundome tilt.
