Leica 40318 Trinovid 8x42HD Binocular

The Leica 40318 8x42 Trinovid HD Binoculars is ideal for people who need a powerful set of binoculars that can also stand up to punishment. The 40318 features phase corrected prisms that are treated with reflective multi-coatings that increase reflectivity and multi-coated optics that increase light transmission through the lenses. These two coatings work in unison to provide a bright image with great contrast and resolution, even in low light environments. The 40318s also offer powerful 8x image magnification to put you right next to the subject you’re observing. Because the internal optical systems of binoculars are delicate, Leica has created a durable housing to protect the lenses from harm. The body is made of a durable magnesium alloy that resists corrosion, but is still lightweight. The body is also covered by a rubber coating that acts as armor against impact damage and provides a slip-resistant surface in wet environments. The binoculars are waterproof and fogproof as well. Leica also provides its proprietary Adventure Strap system that can be configured a number of ways to ensure comfort and ease-of-use regardless of how you’re carrying them.

Multi-Coated Prisms and Optics

The image quality a pair of binoculars provides depends largely on the amount of light that's transmitted though the lenses and reflected through the internal prisms. In the Leica 40318, both of these optical elements are treated with multi-coatings that increase light transmission and refelction. The result is an exceptionally bright image with excellent contrast and color reproduction. Essentially, these binoculars are great for use in environments when light is scarce, like during the dawn and dusk hours. 

Rugged Construction and Special Adventure Strap System

The optical elements in binoculars are delicate and sensitive to vibrations. If they get damaged or knocked out of alignment, your binoculars may be unusable until the affected parts are replaced or put back into alignment. To prevent this siuation the body of the Leica 40318 binoculars are made of magnesium allow that's coated in rubber. Magnesiam alloy is durable but light and the rubber coating provides protection from vibrations and impacts. Additionally, these binoculars come with Leica's Adventure Strap System which is a harness system that allows users to configure the carrying strap in a way that's most convenient and comfortable to them.
