Explore Scientific National Geographic Expedition Series 8×25 Waterproof Compact Binoculars

The National Geographic Expedition Series 8×25 Binoculars combine 8x magnification with a compact 25 mm roof prism design for travel, hiking, wildlife viewing, live events, and other situations where packability matters. BaK-4 prisms and fully multi-coated lenses help maximize brightness and contrast from the smaller objective lenses while keeping the binocular easy to carry in a backpack or with the included neck strap.

Compact 8×25 Optical System

The 8x magnification provides useful detail at short to mid-range distances without making the field of view excessively narrow. A 6.8 degree viewing angle covers 331 feet at 1,000 yards, helping users scan outdoor scenes and follow moving subjects while maintaining a portable form.

Built for Outdoor Carry

The binocular is waterproof, fogproof, and nitrogen purged for changing weather conditions. Its streamlined roof prism body uses a sturdy single bridge, while twist-up eyecups and diopter adjustment allow users to fine tune eye position and focus for more comfortable viewing.

Ready for Travel

The compact body is intended for grab-and-go use and extended observation without the bulk of a full-size binocular. Lens covers, a neck strap, and a storage case are included to help protect and carry the optics between hikes, events, sightseeing trips, and nature outings.
