Kowa BD56-10 overview

  • 1Description

Characterized by a bright and versatile design, the Kowa 10x56 BD56-10 XD Prominar Binocular features an advanced optical system with a series of multicoatings to provide clear viewing in a variety of conditions. Dual Prominar XD elements are used to minimize chromatic aberrations for greater color accuracy, and the phase-corrected Schmidt-Pechan roof prism design avails consistent brightness with a sleek form factor. A C3 coating has also been applied to the glass elements to improve contrast and produce consistent and accurate colors. The 10x magnification is ideal for viewing distant subjects and when all combined with the large 56mm diameter objective lenses, this binocular is especially adept when viewing in difficult and low-light conditions.

A rubberized chassis offers durable and secure handling and the housing has also been nitrogen filled for water and fog resistance. Twist-up multi-step eyecups benefit clear viewing in bright lighting conditions and a KR coating has also been applied to the exposed optical surfaces to protect against dust and dirt, and to aid in cleaning.

Kowa BD56-10 reviews

10x56 BD56-10 XD Prominar Binocular is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great optics and quality I am very pleased with my purchase of these bins. I wanted a nice mid-range pair of binoculars mostly for tripod based use. I am simply in awe at the great optical quality of these 10x56 BD-XD's. Already have taken a fall of about 3 feet onto carpet and were undamaged. Heavy however at over 2 pounds. Was thinking of a higher end model but these will fit the bill for years to come.
