LEICA ULTRAVID 10x42 HD-plus

Leica's 10x42 Ultravid HD Plus Binocular  delivers enhanced contrast and true color fidelity, with virtually zero distortion, even in low-light conditions. Helping compensate for the visually distracting hand-shake common with using 10x and greater optics, is a wide angle 63° apparent viewing angle. This allows the use of high magnification binoculars without the need for stabilization equipment like harnesses or tripods.
Leica upgraded the glass to specially formulated SCHOTT HT glass which increases light transmission especially in the blue-violet light band, improves color fidelity, and enhances low-light performance. Scratch and abrasion-resistant High Durable Coating (HDC), and hydrophobic AquaDura coating on outer lens protect surfaces and causes water and oil to bead off for easier cleaning and clearer vision. The roof prisms feature P40 phase-correction and the proprietary High Lux System (HLS) coatings. These coatings virtually eliminate chromatic aberration for enhanced color rendition and increased contrast. 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.
