This is the stationary viewfinder from the same company that makes the coin-operated binocular scopes found at national parks, boardwalks, and scenic overlooks. The waterproof optics have a 60mm object lens that provides 20X magnification with a fully reciprocating focus and a field of view of 110 feet at 1,000 yards, ideal for observing the city from a high-rise balcony or a passing dolphin pod from the deck of a beach house.
