Transducer and Paint

[redhead78]

hey all, splash getting close....I installed a new depth transducer, should I stay away from it with bottom paint, If I do will it get all barnacled and fouled up?

Paint it with a water-based paint like Pettit Hydrocoat. I have also painted transducers with Interlux Micron Extra with no issues. (The only reason not to paint is some solvents can affect some plastic transducers.)

Mine is coated with Trinadad SR and reads fine with no barnacles....FWIW

Aquatic growth can accumulate rapidly on a transducer's surface, reducing performance within weeks. Surfaces exposed to salt water must be coated with anti-fouling paint.
Use water-based anti-fouling paint only. Never use ketone-based paint, since ketones can attack many plastics possibly damaging the sensor.
Airmar recommends brands such as MDR, Woolsey, Pettit, and Sea Hawk.
Never use spray paint on a transducer. Spraying incorporates tiny air bubbles, and a marine transducer cannot transmit properly through air.
