Hawke Optics Endurance ED 7x42 Marine Monocular with Compass - Blue (36521)

• Built-in Compass: Features an internal compass for immediate bearing reference—essential for verifying your position against landmasses or other vessels.
• Rangefinder Reticle: Equipped with a milliradian (Mil) grid pattern, enabling you to calculate distances to objects of known size, providing a reliable manual backup to electronic GPS.
• Northern Hemisphere Optimized: The compass is precision-calibrated for use in Europe and the USA for maximum accuracy.

• Extra-Low Dispersion (ED) Glass: High-quality ED glass elements virtually eliminate chromatic aberration, delivering high-contrast, razor-sharp images even in high-glare environments.
• System H5 Optical System: Features 18-layer fully multi-coated lenses and phase-corrected BAK-4 roof prisms for superior light transmission and edge-to-edge clarity.
• Wide Horizon View: A generous 393ft field of view at 1000 yards makes scanning the horizon for navigation markers or wildlife fast and efficient.

• One-Handed Navigation: The sleek, compact chassis is designed for easy one-handed use, keeping your other hand free for the helm or rails.
• IP67 Waterproofing: Nitrogen-purged and O-ring sealed to be fully waterproof and fog-proof, resisting internal fogging in humid or cold marine climates.
