Bushnell designed the Permafocus autofocus system for binoculars for performance and reliability. The optics in this product series use BaK-7 or BaK-4 lenses, with some models having fully coated lenses. Porro prism and roof prism binocular models are available in this series, and these products are designed with a wide field of view so you have the best opportunity of catching the action. You also have a wide choice of form factors and magnification, with compact models and full sized binoculars in this product line. Optical performance should be excellent, though we have not yet tested this product line.
The Permafocus product line has binoculars for just about any need - though no waterproof autofocus binoculars are available. The real differentiator is the "point and view" autofocus system. The system is most effective at medium to long distances - past 100 feet. Just hold the binoculars up to your eyes and you are instantly focused on the action. There are no adjustments needed. The auto focus system does not need batteries.
The price point and easy to use features make Permafocus binoculars a good choice for casual use at sporting events or outdoors.
