Hawke Sport Optics 10x25 Endurance ED Compact Binocular - Green

Lightweight and compact with a powerful magnification to bring distant subjects in close for detailed observations, the green 10x25 Endurance ED Compact Binocular from Hawke Sport Optics is an ideal companion for your daily glassing needs that will easily fit in a day bag, hiking pack, camping kit, or glove box.

Engineered for performance, the Endurance is made with extra-low dispersion glass, phase-corrected BAK4 roof prisms, and fully multi-coated optics to produce color-accurate high-contrast views without distortion or color fringing—so your distant subjects look crisp and clear with excellent resolution. Complementing this optical performance is a fast-focusing wheel that runs through the full focus range in just 3.2 turns, so finding and tracking subjects is fast and easy.

Designed for daily outdoor use in all weather and to make it easy to hold, the Endurance features a lightweight and strong magnesium chassis with dual-hinge bridge. The bridge allows the optical tubes to fold and tuck under it to present an extremely compact profile for easier packing and carrying. An ergonomic and slip-resistant armoring with raised ridges provides a sure and positive grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging if the weather turns or the binocular takes an accidental spill in a stream or puddle.
