About the Brunton 8.5x43 Roof Prism

The Brunton Epoch Full Size 8.5x43 Binocular is a lightweight yet durable multi-purpose binocular designed for a wide range of outdoor glassing. Fully multicoated optics and phase-corrected roof prisms transmit bright images that are as rich in detail as they are in contrast. This model of the Epoch series is configured with 8.5x magnification, ideal for mid-range applications.

An impressive 6ft minimum focusing distance also allows you to see close objects in great detail, making the Epoch binocular a great optic for bird watching. A wide viewing angle, rubber-armored magnesium housing and weatherproof construction make the Epoch a full-featured binocular ready for years of adventures.

Brunton 8.5x43 Roof Prism Features

  • Variable Speed Focus System: Focus from 6'-infinity with a single turn of the focus wheel. When observing a butterfly or on-field action, the fast focus system is useful for always keeping the subject clear. Textured rubber grip pads on focus wheel provide tactile feedback & enhanced focus control.
  • Phase-Corrected Roof Prisms: Phase-aligning and highly reflective AL-HR coatings enable the SF glass prisms to evenly transmit color across the visible spectrum. The resulting images pop with detail and lifelike saturation. Phase-correcting coatings also enhance image clarity
  • Fully Multicoated Optics: Brunton's proprietary Flat-Light 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 Epoch binocular will continue to display bright and clear images
  • Locking Click-Stop Eyecups: Twist-up rubber eyecups lock in place and allow observers to optimize the eye relief and field of view
  • Rubber Armored Housing: The lightweight magnesium housing is wrapped in a durable rubber armor that absorbs shock and provides an enhanced tactile experience. The body is designed for all-terrain activity.
  • Tripod Mountable: An optional tripod adapter enables secure mounting to a tripod, monopod, or window mount. This feature comes in handy during extended-duration activities like bird watching and hunting
