Remarks:

“HG” – High Grade: The term is well justified for this fine instrument. Nikon once made a whole series of “HG-L” binoculars in the configurations 8×20, 10×25, 8×32, 10×32, 8×42 and 10×42, all of them renowned for their mechanical stability and optical excellence. Today, only the 10×25 presented here can still be purchased in optics shops, all others being only available second-hand. This pocket binocular figures definitely among the best 10×25 binos ever made. Lacking the design attraction of e.g. the pocket-size Leica Trinovids or Ultravids, but very nicely finished, mechanically impeccable and optically superior, this binocular is worth every cent of its hefty price tag.
