The instructions for my $80 fishfinder, which I use as a backup for my
"real" depth sounder, says emphatically not to use a glob of silicone
glue to mount the transducer inside the hull.
Any soft glue, like your bathtub caulk, will ABSORB the ping from the
transducer. So, we use epoxy, which is very hard and very conductive to
the ping into the hull for maximum transmission of the sound.
