10.4" COLOR LCD DISPLAY

The CH-250 is a revolutionary, high-performance
searchlight sonar designed for a wide range of
commercial fishing vessels. Fish and underwater
objects are displayed on a compact color LCD
screen. Target echoes are presented in 8 or 16
colors depending on the received echo strengths.
The highest echo level is painted in red and next
strongest echo in orange, and other colors follow with
reducing echo levels. One of the echo strengths can
be displayed in white to enhance the specific echo
level. The background color may be customized for
optimum viewing at day or night.
An operating frequency can be selected from 60, 88
or 150 kHz.
The CH-250 is provided with eight operational modes
including half or full circle scan, zoom, vertical scan,
vertical sounder, the combination of full or half circle
with vertical scan, full circle with history, full circle
with strata and full circle with VideoPlotter. The
combination of full circle and vertical scan mode
helps evaluate the distribution of fish school in
horizontal and vertical planes simultaneously.
The CH-250 has another unique mode "Cross
Section Scan" to view the vertical plane. When you
find a specific echo appropriate "CUSTOM MODE
BUTTON" and then the cross section scan window
appears.
The CH-250 provides three modes to track a
targeted echo: manual mode, target lock mode and
L/L mode. The target lock mode permits automatic
tracking of a target fish school within a
predetermined search zone after it has been
acquired in manual operation. In the L/L mode,
the beam is locked to the position (such as a fish
shelter or reef) specified by the target marker. This
mode can be enhanced with DGPS position input.
The compact display design allows a flexible and
space-saving installation at your navigation station.
With an optional interface unit, a conventional CRT
or LCD monitor can be connected as a substitute,
backup or remote display of the standard display
unit. The low-profile hull unit requires only a limited
space for installation. There is a choice of hull units,
either 250 mm or 400 mm travel.
Power search in eight modes
for fishing and other sonar applications
Sector/Full circle Scan
Vertical Scan
The CH-250 has an
unique "Cross Section
Scan" mode.
You can instantly view
the vertical plane in a
specified direction by
pressing the "CUSTOM
MODE BUTTON".
It is useful for evaluating the concentration and
location of the targeted fish school or navigation
purposes.
CROSS SECTION SCAN
Press the
"CUSTOM MODE BUTTON"

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.
