Re: Depth Transducer back plates and mounting locations.
I hope this provides answers to both replies:
the boat is a Morgan 462 ketch. Airmar did not recommend the transducer you both mention because they are designed for a max hull thickness of approximately 1 inch... or so and If i recall work best with cored hulls and the Morgan hull is solid. It would have been connected to a Raymarine depth gauge.
Defender's recommendation was for a DST800 Smart transducer, but after conversations with Airmar, the DST 800 will not work due the large hull offset angle of the Morgan (about 38 degrees, between the bow and start of the keel. I wanted to exchange the DST 800 for a B122 (recommend by Airmar) and purchase the instrument as well, but Defender said no..
Defender recommended mounting it without a backing plate and suggested mid ship mounting as the hull offset angle is much smaller. But with this configuration, my keel would feel the shallow depth much faster than the depth gauge wold show it...
