How GPS and Cartography Work

Your 700 Series™ Chartplotter supports GPS and chartplotting. It uses GPS to determine your position and display it on a grid. The Global Positioning System (GPS) is a satellite navigation system designed and maintained by the U.S. Department of Defense. GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/- 4.5 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 4.5 meters of your actual position. Your GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area.

GPS uses a constellation of over 24 satellites that continually send radio signals to the earth. Your present position is determined by receiving signals from up to 16 satellites and measuring the distance from the satellites.

All satellites broadcast a uniquely coded signal onceper second at exactly the sametime.TheGPS receiver on your boat receives signals from satellites that are visible to it. Based on time

differences between each received signal, the GPS receiver determines its distance to each satellite.Withdistances known,theGPSreceivermathematically triangulatesits own position. With once per second updates, the GPS receiver then calculatesits velocity and bearing.

Users can customize the layout according to their preferences, ensuring that essential information is always visible.

The 786CI is supported by Humminbird's cutting-edge DualBeam PLUS sonar technology. This feature enables anglers to choose between narrow and wide beam angles depending on their fishing needs. The narrow beam provides high-resolution images of structures and fish at greater depths, while the wide beam covers a larger area, making it easier to locate schools of fish. With CHIRP sonar capabilities, the 786CI delivers enhanced target separation and improves the overall resolution of the underwater images.

Another impressive characteristic of the 786CI is its built-in GPS. The unit comes equipped with a highly accurate GPS receiver that allows for advanced mapping features. Users can take advantage of the Humminbird LakeMaster mapping, enabling them to access detailed contour maps of various lakes and bodies of water. Additionally, it supports optional Navionics charts, giving anglers a broader range of mapping tools to optimize their fishing experience.

The 786CI also includes features like an auto-chart function, allowing users to create custom maps based on their sonar readings. The built-in SmartStrike feature provides insights into the best fishing times and locations based on real-time data and historical trends, enhancing the chances of a successful catch.

Connectivity is another strong point with the Humminbird 786CI. The unit supports Ethernet networking, allowing for integration with other Humminbird devices and accessories. This capability also facilitates sharing data with others on the water, making it a perfect choice for competitive anglers.

In summary, the Humminbird 786CI combines advanced sonar technologies, accurate GPS mapping, and user-friendly features, making it an essential tool for anyone looking to enhance their fishing experience. Whether you're navigating new waters or seeking the best spots to cast your line, the 786CI stands out as a reliable companion.
