Combining comfort and performance, the Burris Optics 10x42 Droptine Binocular features high-density BAK4 roof prisms, low-dispersion glass, and fully multi-coated optics that work together to maximize light transmission and limit internal light-loss, which all translates to bight and clear high-contrast images with accurate color fidelity. Add to this impressive performance a field of view that approaches wide-angle, a comfortable eye relief, twist-up eyecups, and a large focus wheel; and users are presented with an immersive observational experience on the trail, at the range, or in the wild.

Complementing the binocular's optical properties are construction details that allow them to withstand the rigors of the harsh outdoors thanks to optical tubes that are nitrogen-filled and O-ring sealed to be watertight and resistant to internal fogging when moving through extreme temperature changes. Its lightweight and durable aluminum alloy chassis is wrapped in a protective slip-resistant rubber armoring, and textured palm pads provide additional grip strength — especially in cold and wet weather. For long glassing sessions, or to free up your hands, these Droptines can be tripod mounted with an optional adapter.

Optical Performance

  • 10x magnification
  • 42mm objective lenses
  • BAK4 compact roof prisms
  • Low-dispersion HD glass helps to limit color fringing and off-axis coma for true color fidelity, and increased light transmission for brighter, clearer, high-contrast images
  • Anti-reflection fully multi-coated optics produce neutral and accurate color fidelity, and improves contrast and image brightness
  • 300' field of view at 1000 yards

Use and Handling

  • Closed-bridge configuration
  • Large textured fast-focus wheel allows for easy manipulation in cold or wet conditions, or while wearing gloves
