Optical instruments like laser rangefinders (LRFs), sport scopes, and binoculars are actually very easy to use for surveillance and accuracy outdoors. Binoculars give an individual a three-dimensional, magnified view of something at a distance, perfect for bird watching, backpacking, and surveillance operations. Laser rangefinders use laser technology to range the distance of something with amazingly precise accuracy, utilized on golf courses and by hunters. Sport scopes such as rifle scopes and spotting scopes provide high magnification and accurate pointing for wildlife viewing and hunting. These optics are constructed rugged to the environment in most instances and provide bright, high-contrast images, which are useful to professionals and outdoor men.
