Wave action also affects the bottom depiction. Remember that the information drawn is a distance measurement, so if the boat is moving up and down over flat bottom, the bottom depiction often appears in regular variations which match wave timing.

Structure is defined as any object physically attached to the bottom. The sonar configuration of the Wide 3D Paramount is optimized to give the most accurate depiction of bottom structure possible. Grass, trees, stumps, wrecks or other debris are accurately displayed; however, the depiction of these objects varies with boat speed and direction. The best way to learn to interpret structure is to operate the Wide 3D Paramount over a variety of known conditions and experiment with user functions to best represent those conditions on-screen.

Sonar targets which are not physically attached to the bottom may take one of many shapes. Surface clutter is the layer of water near the surface which is rich in algae and other growth, and often is aerated by wind or wave action. This area of water interferes with sonar transmission and often appears on-screen as regular clusters of individual dots near the "0" line.

Thermoclines are sharp differences in water temperature. These are easily identified by the continuous nature of the return.

When a sonar signal is reflected off the bottom back to the transducer, there is often enough energy left in the signal to be reflected off the

surface of the water back to the bottom a second time. Second returns appear as a slightly weaker bottom representation exactly twice the depth of the primary bottom return. The second return is most likely to occur in shallow water and in areas of relatively hard bottom.

The Wide 3D Paramount uses advanced signal processing

to further evaluate any sonar return between the surface and the bottom. For instance, a small school of bait fish usually appears as a dense cluster of individual dots. If the return meets certain additional criteria, a fish symbol will be assigned. There are three different size fish symbols used to indicate the intensity of the sonar return. As in the 3D view, the signal intensity is "normalized" for depth so that a small fish close to the boat does not appear as a large fish symbol. This Fish ID function can be turned off (see User Options) so the unit will display only "raw" information. This allows experienced users to make their own interpretation.

A further method of differentiation of fish symbols indicates which of the six sonar beams detected the return. This gives you a reliable indicator of side to side location relative to boat movement. Fish symbols which are hollow are detected in any of the four outside beams. Hollow fish symbols pointing left are located in one of the

3D specifications

Humminbird 3D is a groundbreaking sonar technology that has revolutionized the way anglers and marine enthusiasts navigate and fish under the surface of water. Utilizing advanced imaging techniques, this system provides an unparalleled view of underwater structures, fish, and other elements, making it a vital tool for any serious angler.

At its core, Humminbird 3D employs a proprietary sonar technology that combines traditional 2D sonar with sophisticated 3D mapping capabilities. This dual functionality allows users to visualize underwater environments in a way that was previously unimaginable. The 3D views offer depth perception, enabling anglers to identify ledges, drop-offs, and other crucial fishing spots with precision. Instead of just a flat representation, users can see the terrain's contours, making it easier to understand the underwater landscape.

One of the standout features of Humminbird 3D is its ability to create real-time three-dimensional maps. This allows users to dynamically adjust their strategies while fishing, as they can continually monitor how fish are interacting with their surroundings. Furthermore, the system boasts enhanced target separation capabilities, making it easier to distinguish between individual fish and structures.

Another key technology utilized in Humminbird 3D is its integration with the CHIRP (Compressed High-Intensity Radiated Pulse) sonar technology. This allows for clearer images and improved target resolution, providing comprehensive details about various underwater elements. The result is greater accuracy in identifying fish species and understanding their behavior in relation to underwater structures.

Humminbird 3D also features an easy-to-use interface, designed to be intuitive for users of all experience levels. The system can be seamlessly integrated into existing Humminbird products, enhancing the functionality of existing setups without requiring a complete overhaul. Additionally, it supports connectivity with other devices, allowing for the sharing of data and enhancing the overall fishing experience.

Durability and reliability are also characteristics inherent to the Humminbird 3D system. Designed for the harsh environments of marine use, it can withstand the rigors of fishing and boating, ensuring that users have a dependable tool at their disposal.

In summary, Humminbird 3D is a game-changer in the realm of sonar technology, providing anglers with unprecedented insights into underwater environments. Its combination of 3D mapping, CHIRP sonar, real-time monitoring, and user-friendly interface makes it a valuable asset for anyone looking to enhance their fishing experience and gain an edge on the water.
