Waterproof binoculars not only protect against rain and leakage, they also prevent fogging. This can be an essential feature, whether you’re on the family boating trip or out hunting or camping with mates.
Waterproof binoculars also great when in high-humidity situations or when dew is heavy as they will not fog up.
By using waterproof binoculars you can hunt whenever it’s convenient and or safely see better while out boating. The self-contained parts of a waterproof set of binoculars will also be safe from dust and dirt.
Finally if you store your binoculars on the boat or in the campsite for easy access, waterproofing will ensure your binoculars are protected from getting dirt or mildew inside.
