This Leupold 10x50mm tactical binoculars is waterproof and fogproof. If you are going to use the binoculars yourself go for a higher quality optics which naturally would cost more. There are many different features to look for when making your purchase.

Since the advent of the original coating, the technique has been refined, and there are several grades of lens coating available. It is also useful in ranging an object that is not perfectly horizontal or vertical, enabling you to determine the range without tilting the entire binoculars.
You can find some secondhand models at affordable prices. Let's face it, you are going to possess these binoculars for a long time, so get a good pair.
