Galvanic Currents can rot through a boat's hull faster than you'd think. Whenever you're connected to an electric hook up, small electric currents flow along the earth cable, and erode fragments of metal from your boat's hull (not to mention her prop & anodes). In a frighteningly short time, this causes pitting, and can even make tiny pinholes in the metal. This is called "Galvanic corrosion"

That's the BAD news ☹️

The GOOD news is that it's easy to prevent Galvanic corrosion with one of our incredibly simple Galvanic isolators. We GUARANTEE that they'll put a stop to Galvanic currrents in your hook up cable.

Don't let THIS happen to YOUR boat!

We have possibly the best range of Galvanic isolators in the UK. The one in the picture above has special high security fixings that are so secure that if your isolator gets stolen, we'll replace it FREE. (We've sold thousands, and have never had to replace one yet). 

NO electrical knowledge is needed. You just plug the isolator on to the end of your hookup cable. It doesn't matter which end you connect it to - it works equally well.
