The waterproof and shockproof sleek desiged VX-R features daylight-capable illumination. Its patented 1-button design minimizes bulk, while allowing users to select between 8 intensity settings, including a low/high indicator. The readily available CR-2032 coin-cell battery produces remarkable runtimes, while the fiber optic light pipe eliminates the need for an eyepiece-based control module. Proprietary motion sensor automatically deactivates illumination after 5 minutes of inactivity, yet reactivates instantly as soon as any movement is detected. Leupold's legendary Index Matched Lens System combines with edge-blackened lead free lenses for astonishing clarity and light transmission, while the extreme fast-focus eyepiece ensures optimal diopter adjustment in the field. The 30mm maintube and finger-click adjustments assure maximum adjustment precision, while the second generation waterproofing resists the effects of thermal shock much more efficiently than standard nitrogen.
