I was lucky in acquiring three sets of binoculars over the years and all were acquired by trade or purchased used. They serve distinct purposes. The oldest pair are an odd magnification, but I prefer them for birding. Zeiss Dialycht 6 x 42 roof prisms (armored) that I bought in a local camera shop for $300 and they had been rarely used. 1 lb., 14 oz. I traded a pair of Nikon 7x50 for a pair of armored Fujinon Meibo 7 x 50. I used them on my saltwater rig and for stargazing. They now sit in my desk drawer at work and I scan the horizon from my fifth floor for birds of prey. The Nikons were actually better optically with pin point star images, edge to edge, but were on the delicate side for marine use. The Fujinons are heavy enough to kill a deer with a head strike. I bet they are five pounds. My third pair are Leica 7x20B. Compact and an easy carry.
