I like the depth transducer forward to get as much warning as possible. Maybe
a few feet doesn't sound like much to most of you but I tend to bounce the keel
frequently. :)
While most of you have a depthsounder, I have a "Debsounder". The Admiral,
Deborah, has some sort of mental connection with Touche'. When her "pucker
meter" edges upward, she advises me and I change course to deeper water. She
is rarely wrong. I remember more than one occasion when I was assuring her we
were in plenty of water when "bump". Ooops!
The transducer in my previous boat was mounted in a silicone blob on the inside
of the hull. Worked years with no issues.
