A boat compass stands as an indispensable navigational instrument utilized on watercraft to establish direction and ensure precise course-keeping. Designed for durability and reliability in maritime settings, the compass is typically compact, strategically mounted for accessibility, and crafted from materials resistant to saltwater-induced corrosion. Engineered for stability and readability, it often incorporates damping mechanisms to counteract the influence of boat motion on the compass needle. Adhering to the CB/T3966-2005 "boat" standard magnetic compass, they exhibit a beautiful shape, rational structure, and user-friendly design. Widely applicable to captains of all kinds of boats and rafts, these magnetic compasses serve as crucial tools for navigation, ensuring safe and accurate passage on the water.
