8 Maintenance
8.1 Antifouling Paint
Surfaces exposed to salt water must be coated with anti-fouling paint. Use water-
based antifouling paint only. Never use ketone based antifouling paint, since ketones
can attack many plastics possibly damaging the transducer. Apply antifouling paint
every 6 months or at the beginning of each boating season.
8.2 Cleaning
Aquatic growth can accumulate rapidly on the transducer’s surface, reducing its
performance within weeks. Clean the surface with a soft cloth and mild household
detergent. If the fouling is severe, use a stiff brush or putty knife to remove the growth
taking care to avoid making scratches. Wet sanding is permissible with fine grade
wet/dry paper.
