If i get nowhere with these ill sell the two units if some one wants them.
I wonder if the boat is too thick, (6mm plate).

Can you give details for the suppliers of the boards and transducers. Kits from Jaycar now seem to be expensive.

Update - provisionally sold, but I'll keep a reserve list just in case this sale doesn't complete, so let me know if you're interested.
Update - kit now sold. If you still want one, buy it from Jaycar - 3 - 4 weeks delivery, then pay VAT and import duty.

Reason: Kit sold, no longer available.
Just my two Eurocents: Since I started adding red chili pepper powder (ground) to my AF on my 33' steel SY, I'v seen no barnacle or algae growth on my boat. Before that, all kinds of seapocks, barnacles and mussels saw the boat as their favourite place. About 50 grams per liter of AF will do fine. Just give it a try - it's non-toxic, and you can buy it at gross-outlets for restaurants at amazingly affordable prices.
So, no need for underwater ultrasound! Wouldn't that even potentially interact with the depth sounder?
Totally different question, from a non-native speaker: Why is it called ultrasonic? Isn't that the word for planes flying faster than sound? What's the topic here, shouldn't it rather be spelt ultrasound (which describes sound at frequencies normally not hearable by humans)?
Cheers from the Kiel Bay.
Jaycar seems to have ceased trading
I ordered a kit, Jaycar took the payment but I never received the kit. I can't get a response from them either by phone or e-mail.
they are still trading. They normally prity good keep on there case.If no joy send me an email with order number and ill try chase it up.

As you correctly say, ultrasonic is a reference to sound waves of frequencies above the human hearing range. (I wonder if I could persuade my wife to be ultrasonic?)
