Should I antifoul over the transducer for my echosounder (Autohelm unit, late '90's vintage) or do I leave it unpainted??

Thanks,

Graham.
 
Re: Antifouling & Transducer

At the boat show we were told that some transducers, plastic fails if antifouled. So manufacturers tell you never to do it ...
 
Antifoul doesn't stop it working but digging out encrusted barnacles from the transducer face might! You can mount a transducer in an oil bath attached inside the hull and it will work, slightly reduced depth range maybe but above 300ft who cares! The reason they say don't antifoul is that the solvent in some antifouls could attack the plastic, that applied more I think in the days of 'hard racing' antifouls and the solvent for those with the strong peardrop smell. I have antifouled transducers without problems for over 30 years, I could be wrong though.. /forums/images/graemlins/smile.gif

3-3 now, you're not helping /forums/images/graemlins/wink.gif

Maybe YM can do a test - 2 sets of 12 transducers, one lot antifouled (using different brands), one lot not.

What a great basis for an article!!

or not

Well 30 years or more is not really a long enough trial, there could be side effects. Mine went splash at 0830 today with an antifouled transducer too, I like living dangerously! /forums/images/graemlins/laugh.gif

If you can't anti-foul a transducer - then how does it work through hull ...... do you leave a patch "clean" special where transducer is ?

Commercial ships don't AF transducers - buts that because they want echoes from deep not shallow Solent etc. but I've seen many a Dry-Dock spraygun cover them ....

The only reason I can see for not doing it - is if the AF had a component in it to attack the Transducer ...... which probably nowadays seeing as AF can't even attack what it is designed for is unlikely.

No, I couldn't find the leadline and some idiot had antifouled the echosounder transducer. /forums/images/graemlins/shocked.gif
 
Re: Antifouling & Transducer

Sod it, I'm going to paint the transducer and blow the consequences!!

Any suggestions re colour /forums/images/graemlins/wink.gif
 
Re: Antifouling & Transducer

Red ...

so you can identify it clearly ... /forums/images/graemlins/smile.gif


We AF ours ... bother it ... I don't want barnicles stuffing up my depth readings ...

Our speed transducer is retractable so not so bad - and it tends to get little critters around the spindle that stop the paddle, rather than growth on the paddlewheel.... /forums/images/graemlins/frown.gif

OK, red it is.

Anyway, back to the fog/ buoy/ Yachtmaster conversation... /forums/images/graemlins/crazy.gif

Claymore works on the following principle.
A transducer will fail to work.
If you don't antifoul it and it fails to work then at least you haven't had a hand in making it fail
If you do antifoul it and it fails then perhaps if you hadn't it would have been fine.
