Cross Track Error (XTE): Cross Track Error is the straight-line distance of the boat from the intended Track. XTE measures how far the boat is off course, and also triggers the Off Course Alarm. See Track.

Differential GPS (DGPS): Differential GPS is a system to improve the position accuracy of the Department of Defense GPS through the use of secondary “correction signals” broadcast from ground stations around the coastal United States and on some inland waterways. These correction signals are provided by the USCG and received by an auxiliary Differential Beacon Receiver (DBR) that connects to the GPS receiver. The advent of WAAS has largely negated the need for the added expense of a DBR in the United States.

Distance To Go: Distance To Go is the straight-line distance between Present Position and the Destination Waypoint. DTG and SOG (Speed Over Ground) are used to calculate Time To Go. See Time to Go and Speed Over Ground.

Estimated Position Error (EPE): Estimated Position Error is a calculation that indicates the potential position inaccuracy the user may experience due to a variety of GPS factors which include satellite position in the sky, signal strength and others factors.

Fix Type: Fix Type indicates whether the GPS receiver is providing 2D fix or 3D fix. A 2D fix requires only three satellites and provides only latitude and longitude. A 3D fix requires four or more satellites, and provides latitude, longitude and altitude.

GPS: GPS is an acronym for Global Positioning System. GPS provides accurate position (latitude, longitude, altitude) information virtually anywhere on the earth through satellite technology and personal receivers on the ground. A series of geosynchronous satellites broadcast a unique signal toward the earth once per second. A GPS receiver, such as that included with many Humminbird® products, receives the signals from these satellites and is able to determine position based on very slight differences in the time each signal is received and the receiver’s knowledge of the location of each of the satellites.

Heading: Heading describes the direction the boat is pointing and is measured in degrees (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is West). Due to wind and waves, the boat is often traveling in a slightly different direction than it is heading, and therefore Heading is often confused with Course Over Ground. See Course Over Ground.

Anglers can choose between a traditional view or an enhanced view, allowing for a more detailed look at the underwater environment. The added water column data helps in recognizing fish movement and behavior, invaluable information for any angler.

Both models come equipped with built-in GPS capabilities. The 787c2i includes a mapping feature that allows for precise navigation on water. The included Navionics Gold cartography provides detailed charts and information about various water bodies, helping anglers to find new fishing hotspots effortlessly.

For connectivity, the Humminbird 787c2i and 757c support an array of accessories, including radar and i-Pilot Link, enhancing the user experience with added functionalities like autopilot and advanced navigation features.

Other characteristics include an accurate temperature sensor, adjustable backlighting for optimal visibility in various lighting conditions, and a flexible mounting system. Overall, the Humminbird 787c2i and 757c stand out not just for their features, but also for their reliability and performance on the water, making them a valuable choice for both novice and seasoned anglers. These fish finders embody the spirit of innovation that Humminbird is known for, ensuring that users have the best tools at their disposal for a successful fishing expedition.
