<h3>Simrad: A Marine Electronics Legacy Built on the Water</h3><p><strong>Simrad Yachting</strong> carries one of the most storied legacies in marine electronics. <a href="/11289-simrad">Simrad</a> traces its origins to 1946, when a Norwegian engineer named Willy Simonsen founded Simonsen Radio — a company initially dedicated to converting surplus wartime radios for use aboard commercial fishing vessels. From those practical, seafaring roots, the brand that bears his name (a portmanteau of <em>Simonsen Radio</em>) grew into a globally recognized force in marine technology.</p><p>Today, <a href="/11289-simrad">Simrad Yachting</a> is part of the Navico Group, a parent company formed through the merger of Simrad Yachting and Lowrance in 2006. As a brand within that portfolio, Simrad has retained a sharp identity: it is <strong>focused on powerboat owners, offshore sportfishermen, luxury cruiser captains, and superyacht enthusiasts</strong> who demand the most from their on-water electronics. The brand draws from the collective expertise of pioneers including Robertson, Simonsen Radio, Shipmate, and Navico — decades of experience spanning marine autopilots, satellite navigation, echo sounders, VHF communications, and multifunction displays.</p><h3>What Simrad Makes</h3><p>Simrad manufactures an extensive range of marine electronics designed to serve vessels of nearly every size and purpose. Their product lineup includes:</p><ul><li><strong>Chartplotters &amp; Multifunction Displays (MFDs)</strong> — From the entry-level Cruise series for straightforward GPS navigation to the advanced NSS and NSX series with SolarMax IPS touchscreen displays, Simrad offers solutions for every helm configuration.</li><li><strong>Radars</strong> — Simrad&apos;s acclaimed HALO pulse compression radar lineup delivers outstanding target detection from close-range maneuvering all the way to extended offshore passages, with features like VelocityTrack Doppler Technology and ZoneTrack alerts.

The brand&apos;s Norwegian heritage means its equipment was forged in some of the most demanding sea conditions on the planet. Whether you&apos;re navigating offshore bluewater, running a sportfishing tournament, or managing a complex glass-bridge helm on a luxury cruiser, Simrad equipment is engineered to perform when it matters most.</p><p>Simrad systems are also designed for <strong>seamless integration</strong>, connecting via NMEA 2000 and Ethernet networking so chartplotters, radar, autopilots, sonar, and instrumentation all communicate as a unified helm. This modularity means boaters can start with a single display and grow into a fully networked system over time.</p><p>From its humble post-war origins to a global marine technology leader, Simrad continues to push the boundaries of what&apos;s possible on the water — combining decades of seafaring expertise with forward-thinking technology that modern boaters can rely on.</p>
