Simrad NSO 4-16 16-Inch Touchscreen Multifunction Display

The Simrad NSO 4-16 is Simrad's big-screen glass helm, a 16-inch touchscreen display that pulls your whole boat's electronics onto one panel. Fishfinder, chartplotter, radar, engine monitoring, onboard lighting, and your AV and entertainment all live behind the same Full HD 1920 x 1080 screen. If you've been squinting at a scatter of small gauges and a dated plotter, this is the upgrade that clears the dash and puts everything in front of you.

Who's it for? Boaters running larger center consoles, express cruisers, and sportfish rigs where there's real estate at the helm for a 16-inch screen. On a boat 25 feet and up you get room to split the screen three or four ways and still read every window at a glance. Sonar, chart, and radar side by side running offshore. Engine data and a camera feed up while you're docking. It's a lot of display, and it earns its footprint when you actually use all of it. On tighter express cruisers under 35 feet, measure your console carefully first, because a 16-inch panel wants room that a flybridge boat has and a smaller helm sometimes doesn't.

The touchscreen is the main way you drive it. Full touch, responsive, laid out so the common stuff is one or two taps away. One honest note from the water: a touchscreen can get fussy in heavy spray or when you're wearing gloves. On an open boat that takes green water over the bow, plan on a keypad or remote, or keep a hand free for the messy days. In a covered helm or pilothouse it's a non-issue.

Networking is where a display like this pays off. It talks NMEA 2000 for engine data, tank levels, and sensors, and it uses Ethernet for the high-bandwidth stuff like radar and networked sonar. Wire it into a Simrad HALO radar over Ethernet and you get radar overlay right on the chart, though on anything past a single unit you'll want a network switch so the connection stays solid. Add a Simrad sonar module and you're running detailed bottom views next to your plotter. It also plays nicely with a Simrad autopilot. Keep the software current, because an out-of-date unit is the usual cause of NMEA 2000 dropouts on these systems.

Charts matter too. It ships with a worldwide basemap so you're not staring at a blank screen out of the box. That basemap is exactly what it sounds like, a broad global reference. For the water you actually fish and cruise, drop in a detailed C-MAP card for your region and you'll get the depth contours, marked hazards, and harbor detail that make a plotter worth having. Think of the basemap as the starting point and the chart card as the real map.

A few things to get right on install. This is a big, glass-fronted display that weighs in around 15 pounds, and that mass puts real torque on the mounting surface. On a fiberglass console, back it with a proper reinforcing plate so the cutout doesn't flex or crack over time, and so vibration underway doesn't work the mount loose. Measure twice before you cut, since a 16-inch opening often runs right into an existing gauge cluster. The panel measures 15.4 inches wide, 9.6 inches tall, and 3.1 inches deep, and on a smaller helm pod that depth leaves tight quarters for the cable bundle behind it.

Power is the other one. This screen runs on 12 or 24 volt DC and pulls up to 33 watts, so give it its own dedicated circuit with correctly sized wire rather than tapping an existing accessory lead. Skimp on the wire gauge and voltage drop can reboot the unit, especially on older boats with a tired house battery. Simrad includes a 9.8-foot 4-pin power cable to get you started, and the display has reverse-polarity and over-voltage protection built in, so a wiring slip is less likely to cook it.

Rated IPX6 and IPX7, the display shrugs off the heavy spray, washdowns, and brief immersion that come with real use. The screen holds an 80-degree viewing angle, so it stays readable from off to the side of the helm, and the finish is black to sit clean in most layouts. One last tip for open boats: mounted in direct sun with no shade, a screen this size can run warm, so give it some airflow behind the panel. Do the install right and it settles into being exactly what it promises, one screen to run the whole boat.
