To adjust the running position of the transducer:

The transducer mounting bracket allows height and tilt adjustment, while the pivot bolt allows angular adjustment. These adjustments will help reduce cavitation. Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the installation after high-speed testing.

1.First, adjust the pivot angle of the transducer body, so it is parallel with the length of the hull of the boat.

2.Fully tighten the two pivot screws, using the supplied Allen wrench. Access to the pivot screws is provided by the lower holes in the side of the mounting bracket. It may be necessary to re- tighten the pivot bolt after initial use as the plastic may still be conforming to the pressure from the lock washers.

3.Adjust the height of the assembly so the face of the transducer is 1/8" (3 mm) to 1/4" (6 mm) beneath the bottom of the transom, and fully tighten the three mounting screws.

4. In order to gain access to the mounting screws, the transducer assembly must be pivoted up in the bracket as shown. Be careful not to alter the running angle as some force is necessary to pivot the

assembly.

 

5.If access to the top mounting hole is not possible due to the selected height of the transducer, fully tighten the two lower screws, then simply remove the headed pivot pin and the transducer assembly, and tighten the top screw, then reassemble.

6.Confirm that the pivot angle has not changed and that all mounting screws are fully tightened.

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.
