Inside the Hull Mounted Transducer
Overview
Before you start the installation, we encourage you to read these instructions carefully in order to get the
full benefit from your Humminbird® accessory.
NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount in
exactly the same way.
Installation
There are a number of ways to install a transducer on your boat. Inside the hull mounting of the
transducer generally produces good results in single thickness fiberglass hulled boats. Humminbird cannot
guarantee depth performance when transmitting and receiving through the hull of the boat, since some
signal loss will occur. The amount of loss depends on hull construction and thickness, and the installation.
NOTE: This type of installation requires the use of a slow-cure two-part epoxy. Do not use silicone or any other
soft adhesive material to install the transducer, as this material will reduce the sensitivity of the unit. Do not
use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, which reduces
signal strength.

Locating the Transducer Mounting Position
Decide where to install the transducer on the inside of the hull, using the following procedures to find the
best location:
1. Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid
ribs, strakes, and other protrusions, as these create turbulence.
2. Make sure that the transducer is located as close to the centerline of the hull and as far aft as possible,
so that it will remain in contact with the water even at high speeds.

Trial Installation
You will not be able to adjust the mounting position after you install this Inside the Hull transducer. In
order to determine the best mounting area (before permanently mounting the transducer), it is best to
perform a trial installation first that includes running the boat at various speeds.
1. Plug the transducer into the control head. Press the POWER key to power on. When the control head
detects a functioning transducer, it will start Normal mode automatically. Press the VIEW key
repeatedly until a Sonar View is displayed on-screen.
2. View the sonar signal at its best by holding the transducer over the side, immersed in the water, so that
it is pointing straight down over a known flat bottom. Use the display to benchmark against the sonar
signal that will be detected once the transducer is mounted inside the hull.
3. Place the transducer body face down at the identified mounting location inside the hull, oriented
as shown in the illustrations (see Transducers with Directional Bias and Transducers without
Directional Bias).

Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to prevent corrosion.
