Birdwatching under extreme conditions will be a piece of cake with the Bushnell Legend E-Series. Thanks to the multi-coated lenses and prisms, you can bring your subjects into razor-sharp focus, with true-to-life colors. Thanks to the magnification factor of 10, you can view your subject in great detail. The binoculars are waterproof and feature RainGuard HD. This means that water flows off of the lenses, so you'll also have a clear view in the rain. The sturdy, magnesium casing is finished with a rubber layer, so it can take quite a beating.
