Trolling Motor Transducer Options
If you don’t have a trolling motor transducer, there are several options:
• You may purchase a Trolling Motor Adapter kit that will allow you to
mount the transducer on the trolling motor.
• You may also exchange your NEW and UNASSEMBLED transducer
(with mounting hardware included) for a trolling motor transducer.
There are also several transducer switches available that support the
following configurations:
• Two control heads with one transducer
• Two transducers with one control head.
