Hi folks, Just bought a Faria dash mounted depth sounder with a
'glue it inside the hull' transducer. Faria warns that it won't work
very good if my hull has core material in it. I am guessing it probably
has 3/4 inch plywood with the outer, and inner fiberglass body shell.

I only need to know when the water is perhaps less than 8 feet deep.
As long as it is deeper I have no worries.

What are the chances it will work o.k. out to perhaps 20 feet if I just
go ahead and glue it in anyway? I really don't want to remove the inner
fiberglass shell, and the wooden core, just to glue the transducer on
the inside of the outer skin.

Anyone currently running a half baked set up like I am going to try?
Do I have to just bite the bullet, and get out the Dremel?

Thanks all!
