Determining the location the transducer
A single answer to the question “where to install the transducer” cannot be given.
The physical location of the transducer depends on the vessel's design and construction, how the hull is shaped, and how the water runs along the hull. There are however a number of important
guidelines, and some of these are even conflicting.
The information here must be considered as general advice. Each transducer installation must be handled separately depending on the hull design.
