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 can send signals up to 60 times per second, as well as produce the varying levels of power output needed for different depths and conditions. Additionally, the transmitter has the capability to create very precise sonar pulses needed for a high degree of target separation. Humminbird® receivers are extremely sensitive, but within a narrow "bandwidth" to discriminate against noise from external sources. Additionally, the receiver offers a wide "dynamic range" which provides the ability to receive very strong signals alternating with very weak signals, without the strong signal overwhelming the weak signal. See Transducer and Noise.

TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. TripLog appears on the Big Digits View, and can be reset to zero through the TripLog menu.

TrueArch®: TrueArch® is a Humminbird® feature that provides true fish arches, not artificial arches or symbols. Humminbird® units are capable of producing fish arches due to the wide 60° sonar beam of DualBeam PLUS™, an extremely sensitive sonar receiver. See Fish Arch.

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.
