The 718 features a high resolution 16 level grayscale 320V x 320H 5" display, DualBeam Plus sonar with 2400 watts PTP power output, and advanced fishing system capabilities.
Freeze frame with ability to mark structure on sonar
Pressing any arrow on the four-way cursor control instantly stops the sonar graphic display to allow a closer inspection of submerged structure, bait fish, and underwater contours. Movable cursor feature allows you to instantly discern depth of any sonar return and mark waypoints from the sonar screen for navigation.
Instant image update
As the boat moves through the water, the sonar chart updates in real time to show the latest information on the sonar screen. A Real Time Sonar (RTS) window shown on the right side of the display always updates at the fastest rate possible for depth conditions.
Real Time Sonar (RTS) window
A Real Time Sonar (RTS) window appears on the right side of the display in the sonar view only. The RTS window always updates at the fastest rate possible and shows only the returns from the bottom, structure, and fish that are within the transducer beam. The RTS window can be displayed as narrow (standard), wide, or off.
Sonar echo enhancement
Sonar echo enhancement shows fish, bait, and more - even watch your vertical jigging on-screen. This is possible through advanced sonar processing and provides the details you want and need. It's important to know what depth the fish are located and equally important to be able to place your lure at that precise depth.
Split screen zoom
Split screen zoom increases the displayed resolution to separate sonar returns that are very close together. In this view, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The zoom preview box on the right tracks the bottom in the full range view.
Many competitive sonar products commonly use post processing software to "enhance" the arching effect produced when suspended targets enter and leave a sonar beam. This additional processing can slow down performance and exaggerate the information displayed. Humminbird's TrueArch technology utilizes parallel processing of sonar data to eliminate unwanted interference and noise and reveal unaltered sonar echoes resulting in true arches of fish targets. This helps anglers more quickly discern the size and depth of fish targets.
Wide narrow cone split screen
This screen separates the sonar data using the two primary user selectable down-looking beams simultaneously in split screen. Fish ID feature shown indicates depth and in which beam fish are detected by changing color, size, and/or orientation of the fish icon.
