The Legend Ultra HD 10x42 monocular is built to give you an amazing optical experience in a convenient and compact package. Equipped with our best ED Prime fluorite glass, the optical performance of this monocular will show you ever detail at a 10x magnification. To keep the lenses clear even in the rain, we coated them with our Rainguard HD coating to repel water so you can see clearly when other optics wouldn't.
