Did you know

Cassens & Plath has been manufacturing nautical precision instruments, including magnetic compasses, since its founding in 1902. The company's compasses are based on centuries of refinement of the magnetic compass principle, which originated in China over 2,000 years ago.
The Neptune is a universal steering compass within Cassens & Plath's yacht compass range, suitable for yachts of all sizes. It is positioned alongside models like the Iota, Delta, Beta, and Zeta, which cater to various vessel sizes and mounting preferences.
The Neptune is designed for high accuracy, with a friction error and directional error of less than 0.5 degrees. Its robust construction, including a watertight float tested under extreme temperatures, ensures reliable performance in challenging marine environments.
