Compact Binoculars

Compact binoculars usually refer to those with an objective lens diameter between 20-40mm. This means they let in less light through the smaller glass, but it also means they are smaller overall. They're great for adults or children, and take up less space in your pack on long hikes. They can be used for hunting, bird watching, and nature observation, but they won't get as crisp an image around dawn and dusk as full-sized binoculars will.
