INSTALLATION OVERVIEW 

 

Your Humminbird fishfinder consists of two primary components to install: the 
control head and the transducer. 

 

The control head contains the sonar transmit and receive circuitry, as well as the 
user controls and display. It should be installed in a location that provides access 
to the controls and visibility while in use. The control head mounts on a quick 
disconnect mounting system that swivels and tilts providing flexibility for viewing 
from almost anywhere on the boat. 

 

The transducer converts electrical energy from the transmitter into mechanical 
pulses or sound waves. The transducer also receives the reflected sound waves 
and converts them back into electrical signals for display on the control head. It 
should be installed in contact with the surface of the water in an area that has 
smooth waterflow- usually on the transom of the boat. There are several 
mounting options for the transducer. Review the following section to determine 
the method that works for you and your boat.
