Building on the success of the original Ultravid HD, Leica's 7x42 Ultravid HD Plus Binocular adds improved technologies and materials to create an optic with bright and clear images across the entire field of view. The HD Plus delivers enhanced contrast and true color fidelity, with virtually zero distortion, even in low-light conditions. The models of the 42 HD-Plus series are among the most compact binoculars available on the market in their class but their light-gathering power can compete with the larger 50 mm models.
Leica Ultravid 42 HD-Plus binoculars are available with a magnification factor of 7x, 8x or 10x. The 7x magnification is a true leading light and so is ideal for use in the hours approaching darkness. In addition, the 7x magnification offers a steady image, because hand trembling or engine vibrations, e.g. on a boat, are not transmitted. Complementing the optical performance are uncompromising construction details.
To reduce user fatigue during long glassing sessions, the chassis is made of a lightweight yet durable magnesium alloy, with a titanium center hinge axle. The optical tubes are nitrogen-filled for fogproof performance and sealed to make the binocular submersible to 16.4' or 0.5 bar of pressure. Ergonomic thumb indents on the bottom of the binocular coupled with protective rubber armoring provide a comfortable slip-resistant grip. A lubrication-free focus system provides fast and precise focusing, with PETP-Discs to provide smooth movement throughout the broad operating temperature range.
