A golf scope is a small, hand-held tool that measure how many yards are between your golf ball and the hole. Golf scopes are handy if you are playing a strange course and are unsure of the yardage. They come in the form of a monocular, which is basically a pair of binoculars cut in half. Specially marked lines inside the lens help you gauge the distance to hole so you choose the right club.
Stand in the fairway next to your ball with a clear view of the hole. Hold the golf scope up to your eye.
Line up the bottom of the flagstick with the horizontal line marked "Green" in your viewfinder.
Read the numbers that are lined up with the top of the flagstick. That is your yardage. Select the golf club that corresponds with that distance and take your shot.
If the base of the flag is obstructed and the course you are playing has striped flagsticks, line up the bottom line in the golf scope with the lowest visible stripe of the flagstick.
Find the number lined up with the top of the flagstick.
Multiply the number of stripes you can see on the flag by the number lined up with the topic of the flagstick. Then divide by eight. As an example, if the number of stripes you see is five, and the distance you measured in the golf scope was 140 yards, the distance is 87.5 yards.
