Simrad marks its 80th anniversary this year, and rather than celebrating with nostalgia, the company has answered the occasion with one of its most ambitious products yet. The NSO 4 is a ground-up rethink of what a flagship chartplotter should be, built with larger launches and serious offshore fishing boats firmly in mind.
New Zealand boaters can see the system in person at the Auckland Boat Show, where Simrad is exhibiting. The range is distributed locally through Advance Trident.
Central to the NSO 4 is a brand-new operating system called NEON. Anyone who has wrestled with older multifunction displays will be familiar with the problem it sets out to solve. Screens accumulate clutter. Menus breed sub-menus. Tasks that should take a single tap end up buried under several layers of navigation. NEON takes the opposite approach, pulling key functions closer to the surface and stripping away the visual noise. A swipe-to-reveal activity bar puts the most-used tools within immediate reach, without requiring a dig through nested menus. On the water, where conditions can change fast and divided attention carries real consequences, that kind of streamlining has genuine value.
The hardware underneath matches the ambition of the software. An eight-core Qualcomm processor means boot times are meaningfully shorter than previous generations, and route calculations happen without the hesitation that has plagued some rival systems. Whether you are plotting a crossing of Cook Strait or threading through reef country in the north, that responsiveness matters.
The NSO 4 is available in 16, 22, and 24-inch formats. The two larger sizes are well suited to enclosed flybridges and custom helms where display space is generous. The SolarMAX IPS panel maintains legibility in strong sunlight and remains visible through polarised sunglasses. A glass-to-edge finish gives the whole unit a clean, purposeful look that sits naturally in a well-considered helm layout rather than appearing as an add-on.
The NSO 4 is designed to sit at the centre of an entire onboard electronics network rather than simply function as a standalone plotter. It connects with Simrad sonar modules including the S3100H and S5100, supports Active Imaging and Active Imaging HD, and integrates with HALO radar systems. Bird Plus mode will appeal to offshore anglers who work workups by tracking seabird activity. FishCast, powered by ROFFS, lets skippers overlay current and sea-surface temperature data directly onto the chart. For anyone chasing pelagics, that is a practical advantage in narrowing down where to start the search.
Cruising skippers are well served too. Auto routing, chart safety alerts, and radar target tracking reduce the cognitive load at the helm on longer passages. Lighting, audio, and engine data all feed through the same screen, a practical benefit on boats where panel space is limited. Chart support comes via C-MAP DISCOVER X and C-MAP REVEAL X, with updates handled online and coverage purchasable by specific area rather than in broad regional packages that may include far more than a skipper needs.
International pricing for the NSO 4 starts at USD $6,499, with local New Zealand pricing reflecting domestic supply and configuration. It sits firmly in the premium bracket. That said, electronics have become as fundamental to modern boating as hull design or engine choice, and on offshore boats the reliability and clarity of the helm display is not a nice-to-have. With the NSO 4 on show at the Auckland Boat Show and Advance Trident providing local support, New Zealand skippers have a straightforward opportunity to evaluate it firsthand. For those who spend regular time beyond the harbour heads and depend on their electronics every time they leave the marina, it is a system that warrants serious consideration.
