See the real picture

Transducer Safe

Certified by AIRMAR* and developed specifically for transducers to ensure sustained performance.

Propspeed's Foul-Release

Developed from the original foul-release coating’s technology, with the same promise of proven performance experienced by captains and boat owners worldwide.

Easy to Use

The application of Foulfree can be completed in 3 easy steps: 1. Clean - 2. Apply - 3. Let it dry

Biocide Free

Foul-release, not antifoul. Foul-release coatings use physical means to reduce fouling, creating a surface that’s tough for marine organisms to adhere to.

See the real picture

A foul-free transducer equals more clarity, detail and visibility below the waterline.

*AIRMAR certifies that the application of Foulfree coating on its transducers results in no loss in transducer performance.

"Propspeed’s new Foulfree transducer coating is amazing. Goes on easily and smoothly and dries like glass. The transducer looks like a mirror. I can’t see anything sticking to that."
