12.3 Transducer cleaning
Growth can collect on the bottom of the transducer,
this can reduce performance. To prevent the build
up of sea growth, coat the transducer with a thin
layer of water based antifouling paint, available from
your local marine dealer. Reapply paint every 6
months or at the beginning of each boating season.
Certain smart transducers have restrictions on where
antifouling paint is applied. Please consult your
dealer.
Note:
Transducers with a temperature sensor may
not work properly if painted.
Note:
Never use ketone based paint. Ketones
can attack many plastics possibly damaging the
sensor.
Note:
Never use spray paint on your transducer.
Spraying incorporates tiny air bubbles, and a
marine transducer cannot transmit properly
through air.
Use a soft cloth and mild household detergent to
clean the transducer. If the fouling is severe, remove
the growth with a green scotch brite
TM
pad. Be
careful to avoid scratching the transducers face.
If your transducer has a paddlewheel you can wet
sand with fine grade wet/dry paper.
Note:
Harsh cleaning solvents such as acetone
may damage the transducer.
