resolution (vertical multiplied by horizontal) is often less important than the "Vertical Pixel" resolution. See Pixels, Vertical.

Pixels, Vertical: Vertical Pixels are a number of vertical picture elements in a single column on an LCD display. A greater number of vertical pixels provide finer resolution of targets detected by sonar. Essentially, a vertical distance (the depth), when divided by a larger number, breaks that distance into smaller samples, each representing a smaller area and thus providing more detail. In fishfinders, vertical pixels are more critical than horizontal pixels because the horizontal axis of the display represents time, or history. Sonar information on the horizontal axis can vary greatly, depending on boat speed and the Chart Speed setting. A greater number of horizontal pixels show more sonar history that the boat has passed through. On many models, Humminbird® provides the most vertical pixels to provide a better display resolution. See Chart Speed and Pixels.

Power Output: Power output is the amount of sound energy emitted into the water by the sonar transmitter. Power output is measured using either RMS (Root Mean Square) or P-T-P (Peak-to-Peak) measurement systems. Either method is acceptable, but it is important, when comparing power outputs, to make sure that the same measurement system is being used for both outputs, because P-T-P numbers are 8 times higher than RMS numbers. Greater power output allows the sonar signal to penetrate through weeds and thermoclines, reach deeper depths and operate more effectively in noisy environments, such as when the boat is running at high speed.

Pulse Width (Pulse Length): Pulse Width is the length of time that a sonar sound burst is transmitted into the water. Shorter pulse widths provide better target separation, but cannot travel to great depths. Longer pulse widths provide better depth penetration, but result in poorer target separation. Humminbird® varies pulse width based on depth to optimize both target separation and depth performance. See Target Separation.

QuadraBeam™: QuadraBeam™ is a Humminbird® sonar configuration that uses four sonar beams for a more detailed bottom image. QuadraBeam™ uses the DualBeam PLUS™ configuration for downlooking, and also adds two additional beams to look to the left and right. The sonar beams pointing to the left and right provide the ability to spot fish and structure over a wide 90° area, and to identify on which side of the boat they are located. See DualBeam PLUS™.

Quick Disconnect Mount: The Quick Disconnect Mounting system is an exclusive Humminbird® feature that permits the unit to be easily removed from the mounting base by pressing a release button, and re-installed by simply snapping it back into place.

383c specifications

The Humminbird 383c is a powerful fish finder that combines advanced sonar technology with ease of use, making it an essential tool for anglers looking to enhance their fishing experience. This model features a large, vibrant 3.5-inch color display, offering crystal-clear images and easy navigation through menus and settings.

One of the main features of the 383c is its DualBeam PLUS sonar system, which provides exceptional coverage and detail. This technology allows you to select between two beam widths, giving you the flexibility to focus on a specific area or cover a more extensive zone. The 200 kHz beam offers a narrow, detailed view, making it easier to identify fish and structures, while the 83 kHz beam provides a wider coverage area, ensuring you don’t miss any potential hotspots.

The 383c also boasts a built-in GPS chartplotter, which is ideal for mapping out your favorite fishing spots and navigating with precision. This feature can store up to 2,500 waypoints, allowing you to mark locations of interest, such as fishing holes, underwater structures, or hazards. The unit is compatible with Humminbird's proprietary mapping software, including LakeMaster and Navionics, providing access to detailed charts for numerous water bodies.

Another highlight of the Humminbird 383c is its Fish ID+ technology, which simplifies the process of identifying fish species. This system utilizes sonar returns to provide visual icons representing different types of fish, allowing anglers to quickly assess what’s below. The built-in temperature gauge is yet another valuable feature, providing real-time water temperature readings, which can help in determining the best fishing strategies based on fish behavior.

The unit’s user-friendly interface ensures that even novice anglers can operate it with ease. The menu system is intuitive, allowing users to access essential functions quickly. With its durable construction and waterproof design, the Humminbird 383c can withstand the rigors of fishing environments, making it a reliable companion on the water.

Overall, the Humminbird 383c blends advanced technology with practical features to deliver an exceptional fishing tool. Whether you are a seasoned angler or just starting, this fish finder is designed to enhance your fishing trips by providing accurate information and increasing your chance of a successful catch.
