the apparent sensitivity because the weaker signals appear bolder. Inverse grayscale works well in very clear water. Debris-laden water often appears as a lot of clutter on the screen.

Instant Image Update: Instant Image Update is a Humminbird® feature that updates all the sonar information on the display when Sensitivity and a variety of sonar settings (Bottom View, Range, etc.) are modified. This differs from the traditional functionality that only updates the new sonar information collected after the setting change. Instant Image Update permits more accurate fine-tuning of the display because the user can see the results on the complete sonar graph. When combined with the Freeze Frame feature, the user can adjust and understand the effects of many different sonar settings quickly and easily.

Maximum Depth Menu: The Maximum Depth Menu is a Humminbird® feature that optimizes performance based on the maximum operational depth set by the user. Many Humminbird® units can operate across a very broad depth range (up to 2500 feet) which causes the unit to "look" up to that full depth under some circumstances. Due to the speed of sound in water, this can result in less responsiveness because the unit has to wait for a longer period of time to receive the sonar signal. When the Maximum Depth menu is set to a lower value, the unit only looks up to the setting, which increases the responsiveness of the unit. This is an important feature for anyone operating in shallower depths!

Noise: Noise is unintentional, external sound waves that interfere with the optimal operation of sonar. Noise appears as random "dots" on the display, and is caused by a variety of sources. Electrical noise (from trolling motors, bilge pumps, VHF radios) typically manifests as a consistent dot pattern. Electrical noise can be isolated by selectively turning on and off other electrical devices to determine the source. Often re- routing the power cable, or connecting to an alternative power supply (second battery) can help overcome electrical noise. Hydrodynamic noise (from propeller and/or hull cavitation) has a more random appearance and is generally related to boat speed, so that faster operation results in more noise. Hydrodynamic noise can be overcome by proper transducer installation. Many Humminbird® products have a Noise Filter menu setting that allows the user to clear the screen of noise that is difficult to eliminate.

Pixels: Pixels are the "picture elements", or small square blocks, that make up the image on the LCD. Measured as a vertical by horizontal number (i.e. 640 V x 320 H), this key specification typically indicates the quality of resolution. In fishfinders, the total

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.
