Yeah, I use them until I have enough for a sniper rifle or a scope for a hunting rifle pops up. After that I give them to my followers and pretend they use them. lol
Binos seem like one of those odd things just added to the game for atmosphere and to give RP'ers a little giggle... because for all practical purposes they are about as useful as the toasters or butter knives laying about, considering the scope you can get on the beginner varmint rifle is far superior to them. Why didn't they give them some advantage over even an average rifle scope? Like Lady C mentioned previously, not only are they inferior in performance to any rifle scope, but you have to either waste time opening up your pipboy just to select and use them, or waste a valuable weapon-slot on them. All downsides, no upsides... unless you are too clueless to find some kind of scope early on, I guess.
