What are the advantages of a monocular?
As they require only one eye, you can simultaneously keep your other eye on your surroundings when using your monocular – useful for when you’re out in the great  outdoors. Monoculars are also easily adjustable on the go, making them a good choice for bird watching and wildlife spotting.
