Foulfree and Lightspeed coated versus uncoated transducers and underwater light

About

A picture is worth a thousand words. The transducers and underwater light pictured above were left uncoated on the left side, with the right sides coated with Foulfree and Lightspeed, respectively.

Foulfree™, developed in conjunction with world experts AIRMAR, was designed specifically to protect its transducers from marine growth. As transducers provide best results with minimal turbulence over their surface during operation, Foulfree™ keeps any transducer performing at its peak, ensuring that the signal remains clear over time*.

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

Lightspeed, endorsed by Lumishore, is an award-winning foul-release coating that protects underwater lights from the negative impact of marine growth on performance and lifespan. Lightspeed offers an eco-friendly and trustworthy solution for boat owners to reduce maintenance, protect their investment, and maintain lighting system output.

The transducers and underwater light were submerged in the Whau River, an estuarial arm of the Waitemata Harbour in Auckland, New Zealand, for 14 months. Propspeed’s Technical Manager, Gabriel Larribe, recently retrieved them from the river and rinsed them with water. The transducers and underwater light displayed heavy fouling on the uncoated left side, with the coated right side, clean and free of fouling.
