Why do I need Foulfree?

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.

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.
