I am nearing completion of my re-fit and at same time have installed tranducers for depth and log.
I opted for Navman instruments and installation
instructions for depth transducer included for the following:
Position ahead of keel
Position in an area not affected by turbulence/cavitation etc
Ideally pointing straight down; if not, no more than 15 degrees off centre.
I made (shaped to hull
curvature) a wedge from cedar, epoxied to hull
and faired area with an epoxy
In my opinion, a depth sounder
is a madatory piece of equipment
for cruising. The old timers would not have left port without a lead line, our electronic age has replaced it with a transducer and display; use the technology.
