In Mark's and many other critics opinion, this is the best spotting scope for birding in the world. The pure fluorite crystal used in these scopes is the optimum optical material for reducing chromatic aberration, providing the ultimate viewing experience. The extraordinary light gathering capability supports observation during dusk and during dawn. All spotting scopes are waterproof to JIS protection class 7 and filled with dry nitrogen gas to prevent the lens from fogging.
