13.3 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.
