If you install one like this, you can accomplish two things: (1) You don't
have to slow down your trip in order to have a haulout just at this moment
or operate without depth info and, (2) When you do get a new transducer
installed, you'll then have a backup depth sounder. >>
A new Humminbird depthfinder costs less than $100. These are excellent units,
acurate and sensitive. They will read depths down to several hundred feet.
The factory literature suggests that the transducer can be epoxied to the inside
of an uncored fiberglass hull but I've found that this is overkill. Simply
put a big blob of silicone cauking on the inside of the hull and press the
transucer firmly inton contact with the hull. After the silicone cures, about 24
hours, the depthfinder will work perfectly. I have two Humminbird transducers so
mounted in my Willard. There were intended to be morely temporary
installations but they worked so well I never found need to "properly" install them.

Hi-
Any one have any experience with these transducers installed in a cored hull? I'd be interested in hearing how they work, if the hull is cored.
I've got some one here in Sanford who has asked me to install one in his boat, which has a cord hull, but I'm under the impression that they should be installed only in a hull that are solid fiberglass.
While on the subject, are they effective when installed inside the hull of aluminum or steel boats?

Probably poorly, if at all.

A simple way to determine if they work (and where is the best
position), is to put the transducer in a thin plastic bag, with a
little water, and hold it against the hull where you are planning to
install it. The water will provide an adequate "seal" to the hull, so
you can get a reasonable estimate of performance.
As another poster mentioned, I also feel that epoxy is too permanent a
mounting method - I use Lifecaulk or other soft sealant, and it works
fine.

If you're talking about mounting them inside the hull, no, they won't work
on cored or metal hulls. Need a regular through hull mounting where they
have a clear view of the water/bottom.

Several times in my chequred nautical career I've installed transducer with the boat in the water.
If anyone is interested I'd be happy to give a step-by-step for the procedure.
