SKU: LEU172666 Categories: ,

The 10x binocular is the Jack of all trades when it comes to glassing. It provides enough field of view for tight areas, while delivering enough magnification for wide-open spaces. The BX®-4 Pro Guide® HD 10x42mm is compact, lightweight, and the perfect power for a lot of hunters.

Built around Leupold’s Elite Optical System, the BX-4 Pro Guide HD binocular offers excellent dawn-to-dusk light transmission for a bright image when it matters most, elite-level glare reduction in harsh light, and the resolution and clarity that diehard hunters and shooters demand. The ergonomic, open-bridge design is comfortable for extended glassing sessions and delivers key weight savings for those long backcountry adventures.

It comes with Pro Gear® accessories, too: including a GO Afield™ shoulder strap, binocular case, lens covers, and lens cloth. And like all Leupold® binoculars, it’s fogproof, waterproof, and guaranteed to perform for life.
