Features
Overview: The Leica Monovid 8x20 (#40390) monocular is lightweight and easy to carry in your pocket or purse. It has 8x magnification, and comes with an accessory closeup lens for viewing objects as close as 10-12 inches. The Monovid 8x20 also comes with a wrist strap, eyepiece cap, and a genuine leather carrying case.
Waterproof: The Monovid 8x20 is water-tight to a depth of 5 meters (16.5 feet). The aluminum housing is filled with nitrogen to prevent fogging and condensation forming on the internal elements.
Premium Leica Optics: The Monovid monocular features premium Leica optics for sharp, high-contrast images with superior color fidelity. Leica's High Durable Coating (HDC) protects the outer lenses from scratches, and the AquaDura Coating makes water and oil bead up for easier cleaning. Internally, the roof prism is treated with P40 phase correction coating.
Closeup Lens: The Monovid 8x20 monocular includes a closeup lens that screws into the inner thread of the objective lens for viewing objects at a closer distance. The normal close-focusing distance is 5.9 feet. With the closeup lens installed, you can view items as close as 9.84" to 11.81" (25-30 cm) away.
Eyecup: The adjustable rubber eyecup makes it easy to position your eye at the correct eye-point for the greatest comfort. The eyecup can be extended for non-eyeglass wearers, or retracted to accommodate eyeglass wearers. The eye relief is 15mm.
