Antifouling devices

Hi fellow boaties.
My question is .Has any body tried or used these sonar antifouling devices.Is it any good.Does it work and if so what are the best devices.Im gessing you would still have to antifouling paint.But how long before repainting and how much hull cleaning needed.
Cheers Peter

Re: Antifouling devices

They can extend your antifoul over several years. The Jaycar kit (Silicon Chip magazine design) is the cheapest option if you know how to build electronic devices.

Since this was posted to the multihull forum I should also mention that you'll need one transducer per hull. They also work best on fibreglass, steel and aluminium hulls; not so great on timber or ferro due to lower density.

Lots of opposing opinions about them here's a long thread you may like to consider:
