There are many options from very sophisticated binoculars for surveillance or night navigation to simple binoculars for kids to have fun with.

The Nikon range of compact binoculars is extensive and will have a pair to suit your needs. There are small as well as giant binoculars. For most uses, 8x is a good magnification to choose. Waterproofing should be a must in hunting binoculars, and most of the mid-priced roof prism binoculars offer this feature.

The waterproof models will be corrosion resistant and buoyant, not just repelling water from the lens. But still, a good pair of night-vision binoculars will cost at least a thousand dollars. A pair of binoculars that reads 7x50 can magnify things seven times stronger than they actually are with a 50mm objective lens. Modern lightweight binoculars have also evolved in terms of the use of roof prisms, rather than the traditional Porro prisms.

This may sound obvious, but you need to buy binoculars that are comfortable. Magnification is not the best way of choosing a telescope, as a clear image is more important then simply magnification.
