4. VIDEO SOUNDER OPERATION

With connection of the optional network sounder you can show video sounder
images on the display.

4.1 Principle of Operation

The video sounder determines the distance between its transducer and
underwater objects such as fish, lake bottom or seabed and displays the results
on screen. It does this by utilizing the fact that an ultrasonic wave transmitted
through water travels at a nearly constant speed of 4800 feet (1500 meters) per
second. When a sound wave strikes an underwater object such as fish or sea
bottom, part of the sound wave is reflected back toward the source (transducer).
Thus by calculating the time difference between the transmission of a sound
wave and the reception of the reflected sound wave, the depth to the object can
be determined.
The entire process begins in the network sounder. Transmitter power is sent to
the transducer as a short pulse of electrical energy. The electrical signal
produced by the transmitter is converted into an ultrasonic signal by the
transducer and transmitted into the water. Any returning signals from intervening
objects (such as a fish school) are received by the transducer and converted into
an electrical signal. The signals are then amplified in the amplifier section, and
finally, displayed on screen.
The picture displayed is made up of a series of vertical scan lines, one for each
transmission. Each line represents a snapshot of what has occurred beneath the
boat. A series of snapshots are accumulated side by side across the screen, and
the resulting contours of the bottom and fish between the bottom and surface
are displayed.
