The FE-700 is a result of 50 years of Furuno's vast
range of experience and advanced microelectronics
technology fields in developing echo sounders,
sonars, and underwater application equipment and
systems. This echo sounder is a breakthrough over
the conventional paper eating sounders; there are
no consumable items. The purpose of the echo
sounder is to provide safe navigation by detecting
the clearance below the ship (particularly in shallow
waters) as required on the SOLAS Convention ships
by the new IMO standards.
The basic system consists of a display unit, a
distribution box, a matching box, and a transducer.
The 6.5" high-brightness TFT color LCD display
offers an easy-to-read depth sounding in various
modes, permitting optimum representation with
respect to the environment.
Detection range is automatically varied but there is
manual override to select the required scale. The
displayed record is visible for 15 min on any range
and an instantaneous sounding is directly shown in
large numerals in addition to the graphical display.
Depths, associated time, and position are stored for
24 h in memory. The data can be played back at
any time.
Visual and audible alarms are generated when the
water depth below transducer is shallower than a
user-preset depth. When the seabed is lost because
of the lowered detection or out of range setting, the
alarm comes on. The receiver sensitivity is
automatically controlled with the tracking depth;
manual override is possible to improve the detection
and to reduce the surface clutter.
The transducer is available in 200 kHz or 50 kHz.
The 200 kHz system is advantageous in rough
weather or congested waterways in shallow waters
whereas the 50 kHz system is recommended for
deeper range operation. Depth data can be output
in IEC 61162 format to radar, ECDIS, VDR (Voyage
Data Recorder), and other radiocommunication and
navigation equipment. Optional software is available
to transfer the sounding data to a personal
computer.

You will never be
lost in operation.
The NAV mode provides the basic
function of the echo sounder as
required by the IMO. The FE-700
has various modes to meet the
mariner’s demands. If you get lost
in operation, just select this mode.
When the echo sounder is first
turned on, depths of sea are
measured from the transducer in
meters, the seabed appears in
amber, shallow water alarm marker
is set at 20 m below the
transducer, and the range scale is
automatically varied with depths.
For next start up, the equipment
works with the last settings.
