Alpen Optics Chisos 8x42 ED Binoculars combine extra-low dispersion glass with a compact roof prism design for detailed outdoor viewing. The 8x magnification provides a steady perspective, while the 42 mm objective lenses gather light for birdwatching, wildlife observation, hiking, travel, and general nature viewing.
ED Glass and PXA Phase Coating
Extra-low dispersion glass supports sharp detail and accurate color reproduction. BK4 roof prisms use PXA phase coating to enhance contrast, while fully multi-coated lenses support efficient light transmission. A 368 feet field of view at 1000 yards makes it easier to scan broad scenes and follow moving subjects.
Close Focus and Viewing Comfort
A 6.5 feet close focus distance helps reveal nearby details without giving up long-range versatility. The binoculars also provide 18 mm eye relief and twist-up eyecups, supporting comfortable alignment for users with or without glasses.
Weather-Ready Magnesium Construction
The waterproof body is nitrogen-purged to help prevent internal fogging when environmental conditions change. A magnesium housing provides a durable structure while keeping total weight to 759 g. The result is a capable optical tool for extended observation in varied outdoor settings.
