The PO installed a B&G transducer and I'm validating the depth readings on my Zeus plotter. It typically reads about 1.5 feet more than the factory installed unit. If it's set to read from the waterline, is that the correct offset? Is anyone using readings from the bottom of the keel or transducer installation point (hull)? What is the depth of the keel from the hull?
Thanks,
John
