Humminbird 383c manual

Target Separation: Target Separation is the measurement of minimum distance that a fishfinder needs to be able to recognize two very close objects as two distinct targets (i.e. two fish hanging very close, or a fish hanging very close to structure). Humminbird® fishfinders provide a very good 2 1/2 inches of target separation in shallower than 100 feet of depth. Target separation decreases as depth increases due to the need for longer Pulse Width to achieve greater depth. See Pulse Width.

Thermoclines: Thermoclines are water layer(s) of distinctly different temperatures that create a sonar reflection due to the density of the differing water temperatures. Typically a thermocline will appear as a continuous band across the display at some distance above the bottom contour. Thermoclines are of interest to anglers because fish will suspend above or below the thermocline as they seek the optimum temperature and oxygen levels.

Time Variable Gain: Time Variable Gain is a processing step applied to the sonar return to "normalize" the data so that objects of equal size (i.e. fish) appear to be the same size, even if they are separated by a good distance. Time Variable Gain is a fundamental attribute of good sonar, but is often promoted as a feature.

Total Screen Update®: A Humminbird® feature that refreshes and updates all the sonar information on the display when a range change occurs. Without Total Screen Update®, only the most recent sonar information would be drawn to the new range, and the old sonar information would continue to scroll off the screen at the old range.

Transducer: The transducer is part of the sonar system, which mounts on the boat and is in contact with the water, that converts the electrical energy from the transmitter into sound energy, and that forms the sonar beam in turn. Internally, the transducer consists of one or more piezo electric disks that expand by very minute amounts to create the sound wave. This element also works in reverse, converting the returned sound energy back into an electrical signal that the receiver interprets. Transducers are available for many specific mounting applications for the boat, such as a transom mount, trolling motor mount, etc. Humminbird® offers many sophisticated transducers, often with multiple piezo electric elements designed to form specifically-shaped sonar beams, providing the angler with superior tools for finding and catching fish. See Transmitter and SONAR.

Transmitter: The transmitter and receiver are matched parts of the sonar system that send (transmit) and listen to (receive) the sonar signals, and work in conjunction with the transducer. Humminbird® transmitters have an extremely fast cycling design that

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.
