Humminbird Installation Overview

All Installation Guides can be found at this link.  The guides will be listed under the product Series that you own or under the Humminbird Accessory you are trying to install. 


Determining where to mount the control head unit.

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 mounting system that tilts providing flexibility for viewing.  We do not provide swivel mounts.  There are many third party manufactures of mounts of varying features.  We do not recommend any one brand specifically.  Due to the volume of brands and types within brands, it is impossible for us to test all of these brackets to make specific recommendations for specific models.  

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. 


Determining How to Mount the Transducer.

Your Humminbird fish finder includes a transom mounted transducer. This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat with a two part slow curing epoxy. 

The transom installation, which is the most widely used, places the transducer on the outside of the boat hull. This technique produces the least signal loss, and provides a way to adjust the transducer after installation. The mounting hardware included is designed to protect both the boat and the transducer should the boat strike debris in the water or when trailering. 

As an alternative to transom mounting, it is possible on many fiberglass-hulled boats to glue the transducer on the inside of the boat hull. Since fiberglass has similar sonar characteristics as water, the sonar signal can pass through the boat hull with minimal loss. The hull of the boat must be single layer construction (not double-hulled) and should not contain any foam.  Any air trapped in the lamination of fiberglass would prevent the sonar signal from passing through the fiberglass.  This method will not work for any Side Imaging transducers.   

Inside the hull installations require no holes be drilled into the boat and through experimentation, high-speed operation comparable to transom mounting can be achieved. Two-part slow cure epoxy (not included) is required to glue the transducer in place.  This installation type is not to be used on any Side Imaging or Down Imaging transducers.  This application is only valid for 2D sonar transducers.
