Monocular night vision let you take photographs and videos of things you can't see in the dark with your naked eyes. The compact size and broad field of vision offered by this set of vision monocular cameras from HUNTERCAM makes them ideal for hikers, backpackers, or hunters who don't want to lug a heavy binocular around. Most monocular night vision goggles also allow you to zoom in digitally, allowing you to zoom in or zoom out and change the size of the monocular's field of vision, so you can continue to track an animal even if they move closer or further away from you. This makes them ideal for hunting.
