Fish Finder FOR SKY X5 FISH & COMPACT X5 FISH
The Fish Finder consists of a high power transmitter, sensitive receiver and a
transducer. The Fish Finder sends an electrical pulse to the transducer which contains
an element that converts the pulse into acoustic (sound) wave which is sent through
the water. As this wave travels from the transducer to the bottom, it may strike fish,
structures, thermoclines (temperature changes in the water). When the wave strikes
an object(s) a certain amount of the wave is reflected back to the transducer depending
on the composition and shape of the object. When the reflected wave is returned to
the transducer it is converted into a voltage and is amplified by the receiver, processed
and sent to the display. The speed of sound in water is roughly 4800 ft./sec, so the
time lapse between the transmitted signal and the received echo can be measured and
the distance to the object determined.
