Foulfree

Transducer Defense. Foul-Release.


Fouling on the face of transducers can reduce their sensitivity, decreasing bottom-echo returns and fish targets. Keep your transducer performing at its peak with Foulfree.

The revolutionary foul-release coating that protects transducers from marine growth, certified by Airmar.

If the vessel is hauled for maintenance and a new coat of Foulfree is not applied, is there a limit as to how long it can stay dry?

Foulfree will not dry out, and performance will not be adversely effected when the boat is on the hard.

Why do I need Foulfree?

Fouling on the face of transducers can reduce their sensitivity, decreasing bottom-echo returns and fish targets and reducing the detail on the sonar image you receive. Foulfree forms a slick surface marine growth can’t grab onto, keeping your transducer surface clean and clear. 

Is Foulfree environmentally friendly?

Yes. Foulfree is a specialized foul-release coating that does not poison marine growth or release any toxins into the marine environment.

After applying Foulfree, is there a maximum amount of time that the vessel can stay out of the water?

Our coatings are not effected by extended periods of time out of the water. Foulfree can be applied and then remain out of the water without causing any problems. The coating is UV sensitive when exposed for a long period of time, so we suggest that customers keep the coated surfaces out of direct sunlight. Many customers cover up the coating to also protect it from damage, as it is a soft coating.

Can Foulfree damage my transducer?

No. Foulfree has been tested and proven to have no adverse effects on transducers.

How long will Foulfree last?

Foulfree lasts a minimum of 12 months, with an even longer service life in cooler climates.
