About the Brunton 7x50 Porro Prism

The Brunton 7x50 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 7x 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. Brunton Outdoor Group has been designing and manufacturing outdoor sporting equipment since 1894; whether you are a bird watcher, hunter, or hiker, Brunton has been making gear for nature enthusiasts like you for over a century.

Brunton 7x50 Porro Prism Features

  • BaK-4 Porro Prisms: Highly reflective coatings enable the prisms to accurately transmit color across the visible spectrum. The resulting images are rich with detail and lifelike saturation. The Porro prism design delivers greater depth of field than standard roof prism designs
  • Fully Multicoated Optics: Brunton's multilayer lens coatings minimize reflections within the optical channels and maximize contrast of transmitted images
  • Waterproof/Fogproof Construction: Nitrogen purged and o-ring sealed housing protects the optics from fogging in harsh weather. Even in driving rain and suffocating humidity, the rugged construction ensures that the Echo binocular will continue to display bright and clear images
