Leica 8x42 Trinovid HD Binoculars (40318)
Leica puts a new spin on their perennial favourite, the 8x42 Trinovid HD Binoculars with phase corrected prisms that are coated with highly reflective multi-coatings to increase reflectivity, and anti-reflection fully multi-coated optics to boost light transmission through the lenses. These optical coatings work together to produce high-contrast images with true colour rendition and minimal distortion. This optical performance is coupled with a comfortable 8x magnification, wide exit pupil and generous eye relief to produce an immersive viewing experience.
Description
Complementing the views produced by the Trinovid HD are construction details that make this optic able to stand up to the rigours of a life lived on the trail. First is a lightweight, sturdy, and corrosion-resistant magnesium alloy chassis that makes this binocular light and easy to handle. The body is covered with a textured rubber armour that protects it from bumps and impacts while giving it a slip-resistant grip in cold or wet conditions. Its optical tubes are nitrogen-filled and O-ring sealed to make it waterproof and submersible as well as fogproof when moving between extreme temperature fluctuations. To make handling the Trinovid easier are tethered objective lens covers that flip down and out of the way for observing, plus an ocular rainguard that attaches to the strap.
