The Brunton 10x50 Echo Porro Prism Binocular is a rugged fixed-power binocular useful for hunting, hiking and bird watching. The Porro prism design distinguishes this version from the rest of Echo series binoculars. Porro prism designs generally offer greater depth of field than roof prism alternatives. A nitrogen-purged and o-ring sealed interior provides waterproof and fogproof performance, ensuring that the Echo binocular is ready to withstand harsh weather and driving rain.
This model of the Echo series is configured with 10x magnification, ideal for intermediate to long-range glassing applications. Fully multicoated optics transmit bright, contrast-rich images across the entire focus range. The lightweight aluminum chassis, twist-up eyecups and weatherproof construction make the Echo a full-featured binocular ready for years of adventure.
