are built to tough US Military Standards; binoculars that can take it. When you are out in the field the last thing that you want to do is worry about handling your binoculars like fine china. Fujinon Binoculars have a very deep field of view. What that means to me and you is that when you put those binoculars up to your eyes, your targets are in sight and focused no matter the distance variation from one target to the next. Now of course you will have to set diopter adjustment for each eye in advance but once it is set then you are ready to scope things out. No more lost time trying to focus in on moving targets. Fujinon lenses have an electron beam coating (EBC) to provide the highest light transmission, nearing 95%. That means that you will have a bright view in your sight even when the conditions are not so bright. Keep all the odds in your favor. Buy now and save!
