Vanguard - 8x42 Endeavor ED IV Binoculars

A Guide to Birding with Binoculars

Building on the success of their earlier iterations, the Vanguard Optics 8x42 Endeavor ED IV Binoculars get upgraded with HOYA extra-low dispersion (ED) glass, phase-corrected SK-15 roof prisms, and their advanced MultiGuard optical coatings to improve light transmission, color rendition, clarity, and contrast; while eliminating chromatic aberration. These updated technologies and materials work together to produce an immersive observational experience on the trail, at the range, in the stadium, or sightseeing around town. To pick out feather and fauna details, the binoculars boast an impressive 5.9' close focus distance.

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.

Optical Performance

8x magnification

42mm objective lens diameter

Phase-corrected prisms provides improved light reflection, high-contrast, and true color fidelity

SK-15 prisms have a higher refractive index than BK7 and BAK4, with a lower dispersion than BAK4

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

Use and Handling

Open-bridge/Dual-hinge design

Large knurled center focus wheel is easy to manipulate even when wearing gloves

56-74mm interpupillary adjustment range

±4 center locking dioptric adjustment

Three-stage click-stop twist-up eyecups for comfortable use with or without eyewear

Tripod mountable with optional adapter

Exceptionally long 19mm eye relief

Wide 5.25mm exit pupil completely covers fully dilated pupils in low-light to provide a full-frame view without vignetting

Construction Details

Bridge design reduces weight and provides a more comfortable and secure grip by allowing user's hands to wrap completely around the optical tubes

Lightweight and durable magnesium-alloy chassis

Nitrogen-filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions

Textured rubberized armor provides a slip-resistant grip in cold and wet weather

Flip-down tethered objective lens covers
