Understanding Side Imaging

(1197c SI Combo models only)

It is important to understand how Side Imaging technology produces the display available on the 1100 Series™. The images you see on the display are produced using sonar technology. The special transducer produces three distinct beams – one beam facing down and two beams pointing out to the side. These “side beams” are aimed at right angles to the path of the boat and, unlike the “down beam” which provide conical coverage, the side beams provide coverage which is very thin front to back, yet very wide top to bottom.

The narrow aspect (front to back) of the beam illuminates a small strip of the bottom perpendicular to the direction of the boat. Each time the unit “pings”, a strip of data representing all the echoes received by the transducer, are put together on the display to form the image that you see. The rows closest to the boat icon at the top of the display are the most recent sonar data. The information is scrolled down the screen as new data, drawn at the top of the screen, becomes available.

455 kHz provides maximum coverage with 180° total beam width

The side beams can be operated at one of two frequencies: 455 kHz or 800 kHz. Selecting 800 kHz produces the sharpest image while selecting 455 kHz provides greater bottom coverage area. It is important to understand that when the boat turns, the strips to one side will begin to overlap and the strips on the other side will fan out, providing some distortion to the image. Side beams look out 360 feet, with a depth limitation of 100 to 150 feet, depending on the contour of the bottom and when the side beam frequency selection is set for 455 kHz. Please see the Side Imaging Sonar Tutorial at www.humminbird.com for a more detailed explanation.

Your Side Imaging transducer also provides traditional sonar imaging at 200/83 kHz.

1197C SI specifications

The Humminbird 1197C SI is a high-performance fishfinder that has made waves in the world of angling technology. This device seamlessly integrates cutting-edge sonar technology with an intuitive user interface, making it a favorite among both novice and professional anglers.

One of the standout features of the 1197C SI is its Side Imaging technology. This unique sonar function allows users to see what lies beneath the water's surface, providing a wide, detailed view of the underwater environment. It operates at a frequency of 455 kHz and 800 kHz, enabling exceptional clarity and detail, even at considerable depths. 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.
