Transducer Installation
Plastic housings are recommended for fiberglass or metal hulls. Never
install a plastic Thru-Hull housing into a wooden boat hull. The swelling
of the wood may cause a fracture to occur. Bronze housings are
recommended for wood or fiberglass hulls. Never install a bronze housing
in a metal hull, because electrolytic corrosion can occur. Stainless steel
housings are recommended for metal hulls to prevent electrolytic corrosion
from occurring. Never install a metal housing in a hull with a positive
ground.
The transducer supplied for use with the PcFF80 is a dual frequency 50/
200Khz depth and temperature transducer. The use any other transducer
other than that expressly supplied with the PcFF80 will void the warranty
and can result in damage to the Interface Box. The transducers contain a
crystal element and care should be taken in handling the transducer so as
