depth transducer through glassed ply?

Post by Peter Hend » Sat, 30 Nov 2002 17:51:33


Has anyone had any actual experience with using a navman or similar
depth transducer within the hull of a half inch thick ply hull that
has been glassed over?

If it does work, does it have to be the internal "puck" type, or will
a normal through hull operate effectively from within the hull?

I have to urgently install a new depths sounder.
cheers
Peter

if its a solid glass hull, it should work fine.  Most depth finders come
with the directions on how to do it.  you need to epoxy the transducer
to the hull.  I don't know how well if at all it would work on a cored
hull.

It will not work thru wood.  Usually there is a spot close to the transom in
the bilge that is solid glass for this purpose.  Take some water and put
inside the bilge just enough to cover the floor where you want to mount.
Then try the depth finder.  This will tell you if it will work before
actually epoxying it down.
