The 8x42 Trinovid Binocular from Leica is a high-end, piece-of-art binocular in a class by itself. Leica has endowed this finely engineered glass with their superior optical enhancements. P40 phase correction coating decreases internal light path interference resulting in improved contrast, resolution and color balance. The proprietary HighLux System (HLS) also contributes to greater brightness and enhanced contrast. High Durable Coating (HDC) provides a scratch resistant multi-layer coating of protection for all this excellence. The 8x42 Trinovad is the ideal universal binocular for the field or the stadium, for birding, for enjoying a panoramic vista, for hiking or hunting or for any situation where high quality can make the difference. They afford eye-strain-free viewing well into the twilight hours. The steady image, adjustable eyecups, dioptric and interpupillary adjustments together with a very reasonable eye relief of 15.5 millimeters affords long term comfortable viewing. And they offer generous depth of field thanks to their 8× magnification. Leica 8x42 Trinovid Binocular 2 x Lens Caps Eyepiece Cover Ever-Ready Case Eyepiece Protection Cover
