Complementing the views produced by the Trinovid HD are construction details that make this optic able to stand up to the rigors 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 armor 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. Leica also includes their Adventure Strap system, which is a unique harness system that can be configured multiple ways for easier carrying and handling, while also doubling as a soft carrying bag to protect the binocular when not in use.
The Trinovid 20 BCA is available with a magnification factor of 8x.
