INSTALLATION

INSIDE THE HULL INSTALLATION

3.Power up the Control Head.

4.Run the boat at various speeds and water depths while observing the screen on the Control Head. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fishfinder in water at the desired depth. Test different locations in the hull until the optimum performance is achieved.

Step Three - Permanently Mount the Transducer

1.Once the mounting location is determined, mark the position of the transducer.

2.Remove the water from inside the hull and thoroughly dry the mounting surface. If the surface is excessively rough, it may be necessary to sand the area to provide a smooth mounting surface.

Ensure the mounting area is clear and dry.

3.Mix an ample quantity of two-part slow-cure epoxy slowly and thoroughly. Avoid trapping air bubbles.

4.Coat the face of the transducer and the inside of the hull (Figure 16).

5.Press the transducer into place with a slight twisting motion to purge any trapped air from underneath, keeping the pointed end of the transducer body pointed forward (Figure 17).

Note: Proper operation requires the pointed end of the transducer body to face towards the bow.

6. Weight the transducer so it does not move while the epoxy is curing.

When the epoxy cures, no water is necessary inside the hull. Neither water, spilled gasoline, or oil will affect the performance of the transducer.

In addition to fish identification, the Humminbird 120 packs a range of features designed to help anglers navigate their environment effectively. It includes advanced mapping capabilities, enabling users to create depth contours and view detailed underwater topography. This is particularly beneficial for identifying potential fishing hotspots and understanding the structure of the lake or riverbed.

The device also supports features such as temperature readings, which can be essential for understanding fish behavior and optimizing fishing strategies. The integrated GPS functionality further enhances usability by allowing users to mark waypoints, navigate through previously mapped areas, and avoid potential hazards while on the water.

Another practical aspect of the Humminbird 120 is its ease of installation and setup. Whether you have a small boat or a larger vessel, the device can be easily mounted and configured. The intuitive interface ensures quick access to functions, making it an excellent choice for both novice and experienced anglers alike.

Durability is also key in the design of the Humminbird 120. Built to withstand the rigors of regular use, the device is water-resistant and designed for various environmental conditions.

In summary, the Humminbird 120 combines advanced sonar technology, a clear display, effective mapping tools, and robust durability, making it a valuable asset for any angler looking to enhance their fishing experience. Whether you are searching for fish or exploring underwater terrain, the Humminbird 120 delivers reliability and performance on the water.
