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 placed in the hull.

3.Place the transducer body face down at the identified mounting location inside the hull, with the end that has the mounting knuckle pointed towards the bow of the boat.

Preferred Mounting Area

4.Fill the hull with enough water to submerge the transducer body. Use a sand-filled bag or other heavy object to hold the transducer in position. The transducer cannot transmit through air, and the water purges any air from between the transducer and the hull, and fills any voids in the coarse fiberglass surface.

5.View the sonar signal on the display and compare against what you observed in Step 2, making sure that the boat is in the same location as it was during your observations in Step 2. If the results are comparable, move on to Step 6. Otherwise, locate a new position in the hull and repeat Steps 3 through 5.

6.Run the boat at various speeds and water depths while observing the screen on the control head. If depth performance is required, test the transducer in water at the desired depth. If the performance is acceptable, move on to Step 7. If the performance is not acceptable, repeat Steps 3 through 6.

7.Once you have determined the best mounting location using the above steps, mark the position of the transducer.

3.Route the cable

1.Once the mounting location is determined and you have marked the position of the transducer, route the cable from the transducer to the control head.

This feature is particularly beneficial for identifying underwater structures such as rocks, wrecks, and weed beds, which are often hotspots for fish.

Another innovative component of the 1197C SI is its DualBeam PLUS sonar. This technology provides both a narrow and a wide beam, giving users the versatility to search for fish over a broader area while also honing in on specific targets. The combination of Side Imaging and DualBeam sonar results in an impressive level of detail and accuracy in fish detection.

The 1197C SI also boasts a large 10.4-inch color display, providing crisp visuals and easy navigation through the various features. The screen is designed for easy reading in bright sunlight, ensuring that anglers can rely on it no matter the fishing conditions. Additionally, the unit supports a variety of view options, allowing users to select from different display modes to suit their preferences.

Integration with GPS is another key characteristic of the Humminbird 1197C SI. Built-in GPS capabilities allow anglers to mark waypoints, create routes, and access detailed maps and charts. This feature not only aids in navigation but also helps anglers return to successful fishing spots with ease.

The 1197C SI is also equipped with advanced networking capabilities, enabling it to connect with other devices, such as additional sonar units or autopilot systems. This increases the overall functionality and enhances the fishing experience by providing a more integrated system.

In conclusion, the Humminbird 1197C SI stands out for its advanced technologies such as Side Imaging, DualBeam sonar, and comprehensive GPS capabilities. With its large display and user-friendly interface, it has become an essential tool for anglers looking to increase their success on the water. With lasting durability and a wealth of features, the 1197C SI is a smart investment for serious fishing enthusiasts.
