Swarovski's Laser Guide 8x30 delivers Swarovski Laser rangefinder technology and incorporates the optics of the SLC series roof prism binocular in a beautifully crafted laser rangefinder suitable for the harshest of conditions. Expect a minimum of 1000 measurements from a single CR2 lithium battery, in a housing built to operate in temperatures as low as 14°F. The optics of this instrument are notably brighter and sharper than other flagship rangefinders, in a body which is also surprisingly light.
