A very handy monocular from Eschenbach. The optics give a clear and bright, wide-angle view of the subject, and the spring-loaded collapsable mechanism of the casing keeps the lenses free from dust and dirt when not in use, and allows fast, one-handed opening when you need to use it. Click just below the image to the left (where it says Click here for larger picture) for a demonstration of the closing mechanism. A very popular item!
