6.3 Transducer cleaning
Sea 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: 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. You can wet sand the paddlewheel with fine grade wet/dry
paper.
Note: Harsh cleaning solvents such as acetone may damage
the transducer.
