Simrad NSO 4 24 MFD w/C-MAP Discover X North America Chart

The Simrad NSO 4 24 is a 24-inch integrated glass helm system with a 1920 x 1080 widescreen display, C-MAP Discover X North America charts, and an NSX-powered user interface. It connects to S5100, SonarHub, and StructureScan 3D sonar modules through Ethernet, while Halo 20/20+, Halo 24, and Halo 3000 radar systems are supported. J1939, NMEA 2000, engine interfaces, and three Ethernet ports suit large vessels.

Who Is This For?

This system suits large offshore yachts, commercial fishing vessels, luxury flybridge boats, and integrated glass helms with room for a 24-inch display. The large screen is useful when radar, sonar, navigation, video, and engine data must remain visible together.

It is not ideal for a small boat or a simple chartplotter installation. The sonar modules, radar, and engine interfaces are separate system components, so installation requires vessel-level planning.

Warranty & Support

Simrad provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The NSO 4 24 is the largest integrated glass helm system in this group, offering far more display area than the 15- and 16-inch B&G units. Its strength is system integration through Ethernet, radar, sonar modules, engine interfaces, and video inputs. The trade-off is installation complexity and vessel size, so it is intended for a large offshore or commercial helm rather than a standalone sailing display.
