Adjustable from 17" to 27" in height, the UZI-Periscope has a 5x20 magnification and allows you to surveil around corners, over fences, walls, rooftops, inside drop ceilings, air conditioning vents and even into elevator shafts. Constructed of durable, lightweight aluminum, it can take whatever your adventures throw at it. The weather is no obstacle, as it's also weatherproof. The highly polished glass prisms and lenses give you the clearest possible picture. The handle is completely detachable and the eyepiece is focusable to get a sharp clean visual. The eyepiece rubber cup may be folded back to use with glasses or the wide diopter range makes it completely suitable for those who are far or nearsighted. Plus, it comes with a carrying case, so you can take it to concerts, the cabin, or paintballing. No matter how you use it, you'll know it's quality because it carries the name UZI.
