The Bushnell Powerview Porro Prisms 7-21x 40mm is a wide-angle pair of binoculars with a powerful zoom function. Large 40mm lenses combine with a Porro prism system to create a wide 96m field of view at 1000m from the target when using 7x zoom. This makes it easier to scan a large area for an objective. When the objective is spotted, users can zoom up to 21x, the most powerful zoom in the Bushnell Powerview Porro series. In addition to a wider field of view, the Porro prism system offers a better depth perception, allowing users to gauge distance between objects. Focus adjustment while zooming in and out is managed by a central InstaFocus lever, which can be used without moving either hand from supporting the binoculars. The lenses are multi-coated, which when combined with BK-7 prisms offer superior light transmission for a brighter, clearer image. These binoculars can be adapted to a tripod, and adjust for each individual using a fold-down action on the eyecups.
