With the BX-4 Pro Guide HD binoculars we decreased the magnification and objective size to reduce weight, all while maintaining the level of performance you'd expect from a full-size binocular. The 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 hunters and shooters demand. Features open-bridge roof prism design, twist up eyecups, field replaceable eyecups, over sized eyepiece, aluminum body with shadow gray textured body armor and 1/4-20 threaded tripod adapter. Includes Pro Gear Accessories- Go Afield shoulder strap, binocular case, lens covers and a lens cloth.
