Sorry for top-posting ... seems easier in this situation.

Thanks for all the responses. I learned a lot. Love the clay. I don't know
if I will try it, but it seems as though a good in-hull installation should
work well enough for my needs. I'll get a new unit with an in-hull
transducer and try the old one also. If it doesn't work, I can take it out
down the line somewhere. I think the existing unit is a Seafarer. I know it
is made in the UK.

Anyway, thanks again.

I am inexperienced, so cut me some slack.

I have this 28' sailboat that has an older depth sounder, the kind with a
red light that moves in a circular pattern around graduated markings.
Sorry, I don't remember the brand, and the boat is 2000 miles away right
now. The sounder is unreliable and difficult to read. It uses a
through-hull tansducer that is heavily glassed into the hull. I would like
to replace the unit with something more modern and easier to read. The
question is, is it at all possible to use the existing transducer, or do I
have to buy and install a new one? Is a transducer a transducer, or are
they brand or unit or type specific? Manufacturer's seem to give no
information on this. I'd rather use the existing transducer, of course.

Any help would be greatly appreciated.
