The black 10x42 Echo Open-Frame Binocular from Brunton is a general purpose optic equipped for almost any close to mid-range glassing tasks. This Echo series binocular features a nitrogen-filled housing and open-bridge design that offers weather-resistant performance while reducing excess weight and improving overall balance in the observer's hands.
Slip-resistant rubber armoring and raised gripping ridges on the focus wheel and diopter adjustment ring make the Echo binocular easy to handle while wearing gloves or when conditions get wet. Twist-up eyecups and a 15mm eye relief allow the binocular to create a comfortable viewing distance even for eyeglass wearers.
Complementing the weather-sealed housing and handing features of the Echo binocular is a fully multicoated optical path with BAK4 prisms that render bright images with enhanced clarity. A 56° apparent viewing angle and 8 ft minimum focus distance make this 10x binocular well-suited for birders and nature enthusiasts of all kinds.
