If you connect to an electric hook up, for the sake of your boat's hull, you NEED a Galvanic Isolator!
A Galvanic Isolator sounds complicated, but it's a simple device that prevents unwanted electric currents from coming down the hook up cable, corroding your boat's hull, and eating away your anodes.
In fact, one of the first things our customers notice is that their anodes last FAR longer
You don't need an electrician to fit our Galvanic isolators. They simply plug on to the end of your hook up cable, and allow electricity to pass normally, whilst completely blocking the damaging Corrosion Currents.
