Ritchie Navigation B51 Explorer Bracket Mount Compass Black

Manufacturer

Ritchie Navigation

<p>Founded in 1850 by physicist Edward Samuel Ritchie, Ritchie Navigation pioneered the first U.S.-manufactured marine compass using a revolutionary liquid-filled design. This breakthrough innovation transformed maritime navigation and established a legacy of precision that continues today. Still privately held by the Sherman family in Pembroke, Massachusetts, the company remains the marine industry leader in manufacturing recreational and commercial magnetic compasses.</p> <h3>A Heritage of Innovation and Craftsmanship</h3> <p>Beginning with an order of 26 compasses by the U.S. Navy in 1861, E.S. Ritchie & Company had sold over 30,000 units to merchant vessels by 1900—entirely through word-of-mouth reputation. A model of Ritchie's first liquid-filled compass is on display at the Museum of Science in London, England, the only foreign product so honored, underscoring the brand's historic impact on navigation technology.</p> <p>The company's commitment to quality has driven continuous improvement over 170 years. Technologies developed during World War II—including spherical bowls, internal gimbals, and lightweight aluminum dials—made Ritchie compasses more stable and accurate. In the 1960s, acrylic domes and high-strength plastics replaced glass domes and metal castings to make them stronger and lighter, demonstrating Ritchie's dedication to advancing compass design through materials science.</p> <h3>Precision Engineering for Every Application</h3> <p>At the heart of every Ritchie instrument lies exceptional craftsmanship. All Ritchie compasses use a hardened steel pivot and triple cup sapphire jewel movement, microscopically matched to provide smooth dial operation and fast lock-on under the most severe conditions. In-house machine shop technicians manufacture and finish many of the metal assemblies that go into every compass, ensuring uncompromising quality control throughout the production process.</p> <p>Ritchie's extensive line of <a href="/7528-ritchie-navigation-compasses-200280">compasses</a> serves diverse maritime needs, from offshore racing to recreational boating. The brand offers numerous series including the Globemaster for advanced applications, Navigator for serious cruisers, Explorer for versatile mounting options, and specialized models for kayakers and anglers. Each compass features proprietary PowerDamp technology—a lightweight baffle system that eliminates spinning and dial jumping at high speeds and in rough conditions.</p> <h3>Expanding Beyond Marine Markets</h3> <p>Since the 1990s, Ritchie Navigation has developed products for additional applications including on-road and off-road vehicles, sea kayaks, small dinghies, day sailors, and camouflaged options for outdoor sports enthusiasts. This diversification reflects the company's ability to adapt proven navigation technology to new markets while maintaining the same exacting standards that made Ritchie synonymous with reliability.</p> <p>Beyond core compass products, Ritchie offers comprehensive <a href="/7528-ritchie-navigation-navigation-parts-accessories-200714">navigation parts and accessories</a> to support their instruments throughout their service life. The company also provides specialized <a href="/7528-ritchie-navigation-log-booksreference-books-200629">log books and reference materials</a> to help navigators make the most of magnetic compass technology. Ritchie products are available to retailers in 57 countries through 142 distributors, with OEM parts and service available from Ritchie Navigation headquarters and 76 authorized service stations worldwide.</p> <h3>Why Professionals Choose Ritchie</h3> <p>In an era dominated by GPS and electronic navigation, magnetic compasses remain essential backup instruments that never fail when power is lost or electronics malfunction. Ritchie Navigation's reputation rests on manufacturing compasses that deliver unwavering accuracy year after year. The company's quality control mission includes painstaking evaluation of vendor components before they find their way into a Ritchie device, ensuring that every compass will provide years of accuracy and dependability.</p> <p>Whether you're navigating offshore waters, exploring coastal areas, or seeking reliable direction-finding for land vehicles, Ritchie Navigation combines time-tested mechanical precision with modern materials and manufacturing excellence. From the company's historic first compass in 1850 to today's advanced PowerDamp models, Ritchie continues to set the standard for magnetic navigation instruments.</p>
