Bynolyt Searanger IV 7x50 Marine Binoculars with Digital Compass 00831004
The Bynolyt Searanger IV 7x50 (00831004) are professional-built marine binoculars engineered for high-precision glare, spray, fog, rain, twilight and offshore/coastal lookout and stable real-time bearings. The optical system uses 7x magnification with 50 mm Fully Multi-Coated (FMC) objectives and BaK-4 prisms to minimize reflective and internal light-loss transitions, delivering a bright, crisp and high-contrast maritime image. The digital stabilized Suunto compass displays compass course and bearings in 1° steps with +/-3° tolerance and a graphic display of eight main directions. Tilt-axis support allows compass use under nearly any angle within 60° fore/aft and 45° sideways limits (bearing use side support to 45°), while the LCD also shows tilt angle relative to forward/back tilt (max reference 60°).
The nitrogen-filled sealed barrels (N₂, fog-free optics) manage rapid humidity and temperature shifts without fogging. Both objectives and ocular lenses include a hydrophobic coating that works like a lotus leaf: droplets bead off with no adhesion, ensuring clarity under spray and rain. The shock-protected folding body is wrapped in non-slip rubber to ensure stable grip in wet or gloved deck conditions. Twist-up eyecups support 23 mm eye relief for comfortable use with prescription or sunglasses.
