Installation-Transducer-General,
Transducer
The MC800 is designed to work with either a transom mount type
200 KHZ transducer, or a thru-hull mount 200 KHz transducer.
The transducer element is that portion of the system that converts
the electrical pulse from the sounder into a sound wave which is
transmitted downward to the bottom and returned as an echo. This
echo is picked up by the transducer, converted back into an electrical
signal, and sent to the sounder, which then measures the time the
echo took to return and converts this information for display on the
unit.
The transducer is the heart of the system. It is a delicate instrument
and should be handled accordingly. The thru-hull transducer element
is housed in a lexan casting with an epoxy surface. The epoxy surface
is the "window" through which the ultrasonic pulses travel, and
therefore should be as smooth as possible.
Note
Use extreme caution when handling, installing and using the trans-
ducer to prevent damage to the transducer [ace.
Also, when handling the transducer, avoid lifting by, or pulling on
the transducer cables. This can cause damage to the cable causing
failure at an inopportune time.
Since the mounting location of the transducer will vary with the type
of vessel and it's particular type of hull construction, the following
mounting rules generally apply.
Mount the transducer
. Where it will be continually immersed in water when the vessel
under way.
. Where turbulent water will not passover the transducer face.
. As far from the engine and propeller aspractical.
. Where it will be protected from striking submerged objects.
