Anti-fouling
Where local regulations allow, it is recommended that you coat your transducer using a water-based anti-fouling paint. This will help prevent the build-up of barnacles and other organic growth, which can cause increased drag that will degrade sonar performance.
Anti-fouling
Before applying water-based anti-fouling paint, check that local environmental rules and regulations do not prohibit the use of anti-fouling paint.
Never use copper-based anti-fouling paint as this can impact transducer performance.
Never use ketone-based anti-fouling paint as this can attack the transducer’s plastic, damaging the transducer.
Paint your transducer using a brush, do not use a spray can or a sponge roller as these methods can cause tiny air bubbles to be incorporated in the paint, which will also reduce transducer performance.
The anti-fouling paint should be applied in a thin and even coat covering all externally exposed transducer surfaces.
You should clean your transducer regularly and re-apply anti-fouling paint every 6 months, or sooner depending on how rapidly organic growth builds up.
