TRANSDUCER Installation Guide
It is important to read the instructions in this transducer guide completely to understand the
mounting guidelines before starting the installation.
NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation
guide. Each boat hull represents a unique set of requirements that should be evaluated prior to
installation. For detailed information about installing transducers on different hull types,
download the Transducer Installation Resource Guide from our Web site at humminbird.com.
NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it
will mount in exactly the same way.
Install the control head before you start the transducer installation. See the control head
installation guide.
Review your boat manufacturer's owner's manual for recommended transducer installation
locations and cable routing methods. You will also need your transom angle.
Read and understand your boat's warranty before starting this installation.
