If you like deer hunting or if you just like competitive range matches, you will be able to see your target better with a nikon riflescope.
A couple of hundred years ago, frontiersmen had to hunt for food in order to stay alive. Things aren’t quite as harsh now, but what if they were? If your being fed depended on your hunting ability, wouldn’t you want the advantage a scope would give you?
If I had my pick of any of the Nikon scopes, I would go with the Nikon ProStaff 3-9x40 Water Proof Rifle Scope. I hate it when rain gets on the lens of a scope, an this one doesn't let that happen.
If you are not into hunting, Nikon also has a great set of binoculars you can use at sporting events or just plain old sight seeing. You can check them out here. Ground shipping is free.
