Description
The YF series binoculars from Kowa have high optical characteristics at an affordable price for binoculars of this class. Prisms made of high-quality BAK-4 glass and lenses with full multi-layer enlightenment provide a clear and sharp image with maximum brightness. A special coating of the eyepieces and lenses Kowa KR coating reduces the risk of minor scratches and has water-repellent properties. The lightweight ergonomic body of the Kowa YF 8x30 WP binoculars is equipped with a protective rubber coating, is waterproof and filled with dry nitrogen. A large and convenient central focusing wheel makes the adjustment process quick and convenient even with gloves.
Kowa Repelling ( KR ) Coating is a multifunctional coating specially developed for Kowa SV and Kowa YF binoculars. It is applied to the outer sides of the lenses, preventing scratches and at the same time is hydrophobic. The KR coating protects the lenses from any impact of water (rain, snow, fog, splashes or direct immersion), as well as from the accumulation of dirt dissolved in water. Simply shake the binoculars vigorously after use in wet conditions, and water droplets will be removed from the outer surface of the lenses. This coating is hard enough to prevent accidental scratches from mechanical impact of low and medium force. This will allow the device to be used in more extreme conditions and at the same time maintain full functionality of the optics.

Waterproof - means that the optics are sealed with an O-ring and protected from moisture penetration according to the international class IPX7. Immersion in liquid for 30 minutes to a depth of 1 meter will not cause the slightest damage to the device and will not affect its functionality. Such optics are not afraid of any weather conditions.
Fogproof - means that the body is filled with dry nitrogen from the inside, which eliminates moisture condensation on the internal surfaces when the temperature changes. As a result, the optics do not fog up from the inside, and there is no corrosion of materials under the influence of moisture. Air is removed from the device and replaced with an inert gas (in this case, nitrogen N2), which does not contain water vapor and does not condense.
Lightweight Body - the body of the binoculars of this series is made of particularly light polycarbonate, which allowed to reduce the weight by 10-20% compared to similar models of competitors. At the same time, the balance and ergonomic characteristics of the binoculars only benefited. The device fits in the observer's hands as comfortably as possible, and the durable, combined (partly smooth, partly rough), profiled rubber coating allows you to securely fix the binoculars in your palms.
