An open-bridge/dual-hinge design helps to reduce weight without sacrificing strength, and provides a large surface area to improve grip strength and security. Textured rubber armoring offers protection from drops and impacts, while further improving the grip and comfort in the hand. Designed for durability, the lightweight magnesium-alloy housing is nitrogen-filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions. The Endeavor ED IV's provide the performance and comfort birders, hunters, and outdoor enthusiasts require for long observation sessions in all weather.

  • HOYA extra-low dispersion (ED) lenses virtually eliminates chromatic aberration for true color transmission across the entire field of view
  • Anti-reflection Advanced MultiGuard fully multi-coated optics improves light transmission for brighter high-contrast images with accurate color rendition
  • 377' field of view at 1000 yards
  • Short 5.9' minimum focus distance
