Nikon 5x15 HG Monocular

I'm an avid birder, and I purchased the Nikon 5x15 monocular for business travel in particular. It stows easily in a corner of my brief or computer case. I have already used it while traveling extensively in the Great Basin area. The optics are excellent and exceeded my expectations in clarity and resolution when compared to the 8x optics that I normally use. The wide field of view (9 degrees) helps find and track moving objects, especially fast moving birds, and the close focus is an added bonus for me. However, the 15 mm objective is somewhat limiting in lower light levels as would be expected. The monocular seems rugged in construction and well made, but in the next iteration, I would recommend that Nikon make it water proof and fog proof.
