Designed and Manufactured in the UK to the highest standard, Electronic Fouling Control (formally SonicShield) provides protection for your boat and will eliminate the need to antifoul annually. It works by destroying algae at cellular level and is 100% safe to humans. No algae means there is no food for all larger aquatic life forms such as Barnacles and Mussels.

EFC systems do not require any holes drilled in the boat and are very easy to install. The entire system is supplied with Plug and Play 100% waterproof connectors.
