The monocular is the basis for the creation of more advanced optical instruments. The combination of a monocular with various additional lenses will also make it possible to create a telescopic magnifier necessary for observation from distances equal to the focal length of the interchangeable additional lens, which are only a few tens of millimeters. You can make an observation device - an eyepiece nozzle, increasing the magnification from 10 to 110, depending on the photo lens used. Equally interesting is the use of the monocular as a homemade sighting device for smooth-bore hunting weapons, crossbows, and bows. For lovers of travel, you can also find application for monocular. An interesting option is fixing it on the head (headgear), allowing you to use it without hands. The monocular is lightweight, convenient to use. Equipped in a special handbag-case.
