“Multifunction display” grows in meaning with each new generation of marine electronics. Sonar functions now include traditional down-looking 2-D scanning with and without CHIRP, high-definition side and down scanning, live forward scanning, 360-degree circular scanning and a choice of frequencies to optimize each type for either maximum detail or greatest scanning depth/distance. Most units with Ethernet connections can also show radar scans and forward-looking infrared (FLIR) live video for extra safety when eyesight isn’t enough. They can also share readings with other displays in real time. Units can network with virtually any NMEA 2000 or NMEA 0183 sensor or device and with some engines to show data like RPM, pressure and temperature readings. Many displays can also control autopilots, shallow water anchors, bow-mounted trolling motors, and your boat’s stereo system. All these capabilities compete for the limited space on our displays.
