Description
Kowa has contributed more than a century's worth of knowledge to the design and manufacturing of optics. All optical components of the YFII series are made from high-acid Japanese glass, the surfaces of lenses and prisms are coated with Fully Multi Coated. The YFII series binoculars have a proprietary, dry coating of Kowa Repelling (KR) lenses. The binoculars are 100% waterproof, filled with inert gas, which prevents the appearance of any condensation due to temperature changes. A large field of view of 132 m with a magnification of 8x allows the camera to monitor a wide area from one position, ensuring greater reception of enemy views.
Features:
Fully Multi Coated (FMC) - all lenses and prisms are coated with rich spherical reflective coatings, which allows increasing the light transmission of the optical system and increasing image contrast. Kowa's lens coating technology, refined over decades, further enhances the light-transmitting power of all lenses.
Kowa Repelling ( KR) Coating is a highly functional coating, specially formulated for Kowa SV and Kowa YF binoculars, which can be applied to the outer sides of lenses that are prone to staining and are also hydrophobic and oleophobic. The KR coating protects the lenses from any influx of water (rain, snow, fog, breezes or heavy water), as well as from the accumulation of debris dissolved in the water and oil. It is enough to simply shake the binoculars vigorously after drying, and drops of water will be removed from the outer surface of the lenses. This coating has sufficient hardness and overcomes the appearance of sagging marks with mechanical injection of low to medium force. This allows for the use of extreme minds and thus preserves the functionality of the optics.
Waterproof - means that the optics are sealed with a high-impact O-ring and are protected against penetration by water to the international class IPX7. Being enclosed in a row of 30 ridges per depth of 1 meter does not affect the least harm and does not affect its functionality. Such options are not scary in any weather mind.
Fogproof means that the middle of the housing is filled with dry nitrogen, which prevents condensation of moisture on the internal surfaces due to temperature changes. As a result, the optics do not fog up in the middle, and there is also no corrosion of materials due to the infusion of moisture. The air is removed from the device and replaced with an inert gas (in this case, nitrogen N2), which does not allow water vapor in its storage and does not condense.
Lightweight Body - the body of binoculars in this series is made from particularly lightweight polycarbonate, which allows the weight to be changed by 10-20%, equal to similar models of competitors. With this balance, the ergonomic characteristics of the binoculars are no longer in play. The device fits into the hands of the operator as easily as possible, and the mixed (partly smooth, partly profiled) humic coating allows you to reliably fix the binoculars at the knees.
