About this product

Kowa BD II XD wide-angle series

Introducing the BDII-XD. A range of enhanced optics at the forefront of imaging excellence utilising Kowa’s premium XD lenses. Binoculars that benefit from decades of Kowa optical advancements and the philosophy behind the BDII-XD is simple: Affordable without compromise. A binocular that can be enjoyed by the many, whilst still delivering exceptional image resolution, rugged build quality, superior engineering and comfortable operation.

No ordinary ED-Lens

As with many binocular brands, the BDII-XD series feature ED (Extra-low dispersion) glass to improve optical performance, but the story does not end there. ED glass is manufactured in a variety of quality grades. Every BD II-XD model features Kowa’s environmentally friendly, legendary XD objective lenses. This high-resolution ED glass contains large amounts of the mineral fluorite crystal - the best material available today for light transmission ensuring an image with an edge to edge sharpness and virtually zero chromatic aberration (colour blur). The result: a simply stunning view of the natural world. Kowa lens coating technology developed over decades, further enhance the light transmission properties of all lenses and Kowa’s unique KR coating repels dirt and fluid. Enjoy sharp images with natural colour, high contrast and incredible detail, from dawn through to dusk.

Rugged reliability ensured

Every model in the BDII-XD range benefits from a magnesium alloy chassis, a sophisticated moulding process produces the feel and strength of metal with the added benefit of decreased weight. The lightweight, rugged structure can tolerate the severest conditions and provides a sense of security and longevity. The BDII-XD are built to last. Use them with confidence. Surrounding the tough magnesium alloy body is a protective layer of rubber armour, not only providing a sure, comfortable grip but also increasing the level of durability. Each BDII-XD is fully waterproof and dry nitrogen filled to prevent the lenses from fogging and Kowa’s KR coating protects from dirt and other foreign residue build-ups that may affix to the lenses during use.

Take a wider point of view

One of the stand-out optical features of the BDII-XD series is their enviable large field of view, boasting class-leading wide-angle performance. Viewing is super comfortable on the eye, making long periods of use out in the field a pleasure. The field of view is the area in which you can see through your binoculars and is usually measured in m/1000m or in degrees. For example: at 1000m distance, the BD II 32-6.5XD model can see an incredible image width of 175m. Find a subject quicker with a wider view of your surroundings with sharpness right into the corners of the image, whilst still enjoying crystal clear clarity. The BD II XD series are wide-angle binoculars certified with ISO 14132-2, an International Standard for Optics and Optical Instruments.

Engineered for your comfort

The BDII-XD series are engineered to enhance your viewing experience. A sleek, ergonomic design with a specially selected tactile rubber armour layer ensures easy and comfortable operation - elevating every moment of use. Operation is flawless. A fluid, responsive focus wheel delivers pinpoint accuracy and smooth twist eye-cups ensure optimum viewing for both spectacle and non-spectacle wearers. Tailor the BD II-XD specific to your own viewing requirements with an easy to use dioptre adjustment system. The ergonomic body of the BD II-XD series is as impressive as the optics it protects, with every curve considered to make observation both relaxing and free from fatigue.
