How Far Optical Monocular Rangefinder Works? – Quick Overview with FAQs and More

Do you want to know how far an optical monocular rangefinder works?

Let’s find out!

How Far Does Optical Monocular Rangefinder Works?

An optical monocular rangefinder can work up to 700 yards.

How to Use Golf Rangefinder Monocular? 

Before the competition, practice using the golf scope by taking swings at different distances from the ball. You may need to adjust the settings depending on where you’re hitting the ball.

There are different types of technologies used in the golf scope.

  • Laser
  • GPS signal
  • Optical

You can use either of these devices to get an approximate measurement of the distance between your golf ball and the flagstick.

It doesn’t involve any complex calculations but the golf scope rangefinder helps you to build a strategy for hitting closer to the target.

What is a Monocular?

A monocular is a pair of binoculars that have been split down the middle. The lenses have special markings that help determine the proper length for the shaft of the golf club. Measuring the correct length allows you to select the right club.

Golfers who use the right golf scopes tend to play fewer shots than those who don’t.


  • An unobstructed view is when nothing is standing in between the target and the ball.
  • Obstructed view occurs when there are other objects in between the player and his/her target.

Golf Rangefinder Monocular – Unobstructed View

A clear view makes things easier. So, if you want to learn how to use a golfing rangefinder, just follow these steps.

“Green” Line

To begin, use your rangefinder scope to locate the green line on the scope. Then, look for the flap post by locating the “Flap Post” line on the rangefinder scope.

Once you’ve found the green flag using the “green” laser beam, tilt the golf rangefinder so that the “green” laser beam lines up with the bottom of the flag. It takes extreme care and precision.

To get an accurate reading, be sure to tilt the scope so that the “green” line is perpendicular to the flagstick.

Use the scale to determine which number on your scope represents the highest point on the flag pole.

The corresponding number indicates the distance (yards) from the ball to the target.

Here are the steps for a golf rangefinder monocular – unobstructed view:

  1. Stand near the ball so that you can clearly see the hole.
  2. Hold the golf rangefinders monocular to one eye.
  3. Match the green line on the viewfinder to where the flag pole meets the ground.
  4. Read through the numbered list at the top of the flag post.
  5. After choosing the right club, choose the one that corresponds to the distance specified.

Golf Rangefinder Monocular – Obstructed View

When using the golf scope, obstructions may pose some difficulties for the golfer.

If the base of a flag post is invisible, then there is no way to determine its height. We, therefore, assume that you’re using a striped (or otherwise) flag post.

How can I use a golf rangefinder scope when there’s no clear line of sight?

First, place the golf ball at the desired location. Next, use the “green” lines to determine where the flap post is located. Finally, align the “green’s” with the lowest visible portion of the flap stick.

  1. To align the lowest point of the scope to the green line, tilt the scope carefully.
  2. Next, place the golf scope rangefinder so that the green line is perpendicular to the flag pole.
  3. If you don’t measure accurately, you won’t get accurate results.
  4. Now, look at the grid number corresponding to where the top of the pole is located. It will appear on the viewfinder’s display.
  5. Once you’ve identified the grid square, then use that to calculate the total length of the flag pole.
  6. Subtracting the distance between the hole and the starting point from the total distance gives us the yardage from the ball to the hole.

What happens when the flag post lacks stripes in an obstructed view?

This is a rather tricky situation. In fact, one can never get accurate results in an obstructed condition if the flagstick lacks stripes.

Most golf rangefinders measure distance in either meters or feet. So, the distance exists in either meters or feet (or both).

How to keep your golf scope clean?

Cleaning your golf scopes is an important part of keeping them working properly.

After using it, clean it with a damp cloth. You also need to remove any dust from the lens and scope.

Therefore, your monocular golf distance finder can be used over a long period of time.

Should I Use a Golf Rangefinder?

Rangefinders aren’t for everyone. If you’ve played golf long enough without using one, then it may not be necessary.

  • When you’re not familiar with the course, it’s best to use a golf rangefinder to determine where you need to hit the ball.
  • It’s easy to use, so you can get information on the distances with ease.
  • You can easily avoid the dangers and blind spottings of the course if you choose the right technology.
  • Compactness is one of the most convenient features of the golf monocle. Most of them come with a handy carrying case.
  • You can wear it while playing golf. One of the most important choices you’ll need to make during your turn is deciding which club to use.
  • Whether you’re a pro golfer or just playing for fun, the golf monocular helps you overcome any inner conflicts.


Finding out how to utilize a range finder scope provides a way to improve the equipment in your bag. It’s important in managing your golf course so that you can better strategize your technique during the round.

With the monocular scope, you can avoid the tricky bits of the course. But when using a rangefinder scope on an unobstructed field, the steps are simple. But with the obstructed field, the flag should be marked.
