Shoud the depth sounder work when ashore?

[srm]

Its possible to test a yacht type transducer out of the water. You will need to hold a sheet of smooth dense material about half a metre (or less) from the face and parallel to it. I have used a plasterboard wall with a transducer out of the boat. The sound pulse will be reflect back by the board and register a depth (you may have to play with the angle of the board to get a return). Do not expect the reading to be the correct distance as the speed of sound in air is very different to that in water.

Hello, digging up this old thread for a laugh...,

So we just antifouled our 44 footer - meself and the wife - following helpful advice from some on this forum (thanks!). Job went well over two days but...

I told her to antifoul all the brand new Trudesign skin fittings. So she antifouled over all the skin fittings including the depth sounder. I got to it while the paint was still wet and got most of it off with a microfibre cloth. We didn't have a row which is a positive.

Do I have anything to worry about? Should I clean with anything more powerful? Or is it fine as-is???

The depth sounder will work stuck inside the hull, a coat of antifoul won't stop it working. Only thing to be careful with the transducer is not to use solvent antifoul that might attack the plastic (assuming it is plastic).

No problems, in the days before Coppercoat I would give one thin coat of antifoul over the transducer each year. Coppercoat was applied when I bought the current boat in 2009 and has been pressure washed each year since.
Only problem will be if there are bubbles in your paint - these will compress and absorb the sound waves before they can vibrates the transducer and generate a signal for the display..
