Having full sonar capability built directly into a 4K glass-helm chartplotter means it works as a complete, standalone navigation-plus-fishfinding system with no separate sonar black-box needed, while still carrying the same seven-times-faster processing power and gigabit BlueNet networking as the rest of the 9000-series lineup for smooth performance even when running multiple chart layers, radar overlay, and sonar views simultaneously. It includes the GPS 24xd multi-band position receiver and an NMEA 2000 starter kit in the box, and can be flat-mounted edge-to-edge with other 9000-series displays to build a genuine glass-bridge helm, or flush-mounted individually. RapidReturn sonar technology, one of the sonar modes built into this unit, is specifically engineered to deliver faster-updating sonar returns than traditional CHIRP alone, which matters for tracking fast-moving fish or bait rather than only static bottom structure - all delivered on a 17-inch screen large enough to comfortably split between full-chart, sonar, and radar-overlay panes at once without any one view feeling cramped.
