Perfect for long-range observation, there is no denying that the massive 20x magnification will get you right up close to your subject. However even though these have large 50mm objective lenses that can collect a good amount of light, the very high power results in a small 2.5mm exit pupil and as such, unless you plan on using them for astronomy, they are best used when light conditions are good. These also have a built-in threaded mount to take a standard tripod adapter, which with the high power is essential in achieving a shake-free image. Ideal uses include hunting or wildlife observation from a fixed location like a hide, or setting them up on a balcony with harbor, ocean or valley views.
With a choice of 7x, 10x, 12x, 16x or 20x powers the 50mm Bushnell PowerView porro prism series has you covered in just about any situation where you require an affordable binocular that will deliver a bright image in relation to your chosen magnification.
A distinctive feature is Bushnell's InstaFocus lever. Rather than the traditional focus wheel, you can very quickly adjust the focus by rocking the lever. Apart from improving focusing speed, this design also helps to make focusing easier when wearing thick winter gloves.
All models also have fold-down rubber eyecups and a rubber armour exterior that adds a layer of protection increases grip and improves camouflage.
Multi-coated, these full-sized PowerView binoculars have multiple anti-reflection coatings applied to the outermost lenses that increase light capture and transmission. Whilst this is good and to be expected at this price level, it is important to note that more expensive instruments like the Bushnell Legacy WP Binoculars are Fully Multi-coated meaning that all lens elements throughout the optical pathway are treated for an even brighter view.
Bushnell uses BK-7 glass for the Porro Prisms. These have an advantage over roof prisms because the design naturally reflects 100% of the light and thus they do not require expensive mirror coatings to perform at the same level. Thus at this low price point, Porro prisms binoculars like these will usually outperform equivalent roof prism models as they will use cheaper mirror coatings to keep production costs down.
Bushnell PowerView binoculars are boxed with a soft carry case that includes its own carry strap, objective and ocular lens covers, neck strap and cleaning cloth.
Made in China, Bushnell present these binoculars with an impressive 10 year warranty.
