The Sestrel Navigator is a legendary marine magnetic compass produced under the iconic Sestrel name and maintained by John Lilley & Gillie Ltd. Engineered for exceptional stability, readability, and lifelong reliability, it is widely utilized as a primary steering compass or reliable emergency backup on commercial workboats, sailing yachts, and coastal vessels.

Featuring an internal dual-axis gimbal system, sapphire jewel bearing, and a hardened steel pivot, the Sestrel Navigator maintains card levelness and dead-beat dampening under heavy vessel pitch and roll. Housed in a heavy-duty brass bowl with an integrated lighting ring, it provides uninterrupted, non-electronic heading reference under all marine lighting and weather conditions.

Key Features:
• Internal Gimbal System: Built-in two-axis gimbal maintains card horizontality during intense ship motion.
• Precision Jeweled Bearing: Sapphire jewel and hardened steel pivot deliver friction-free, highly responsive card movement.
• Dead-Beat Card Dampening: Specially formulated compass fluid minimizes oscillation and card spin in rough water.
• Integrated Night Illumination: Includes built-in 12V/24V DC night-vision lighting for easy night watch reading.
• Corrosion-Resistant Brass Construction: Built with a heavy brass bowl and protective marine coating for harsh ocean environments.
• Flexible Mounting Capabilities: Ideal for bracket mounting, bulkhead installation, or storage in wooden transport cases.
