Spotting scopes are essential to hunting, bird watching and a plethora of outdoor activities. These devices are basically a small portable telescope with additional optic enhancements that present a clear image that is highly optimized for viewing objects in the distance.
Often used for birdwatching, hunting and verifying marksmanship they are great for activities that require more magnification than binoculars.
Additional capabilities include light-gathering power in the lenses and increased resolution which is determined by the diameter of the objective lens which is typically 50 to 80mm.
