How to Use Golf Rangefinder Monocular? For the Best Distance Approximation!

My first encounter with this device wasn’t so pleasant. I didn’t know how to use it. As a result, I had to keep consulting with my friend (I doubt if he enjoyed the distraction). After that day, I buried myself in books, attempting to figure out how to use golf rangefinder monocular.

How to Use Golf Rangefinder Monocular? For the Best Distance Approximation!

After research and regular practice, I finally got the basics. I kept sharpening my skills, and finally, I was an expert. My experience wasn’t an isolated one. I have seen many amateur golfers go through the same.

If you are going through the same predicament, here comes some good news! I will guide you through each step. In the end, you will have acquired the basic skills. So, relax and read through this comprehensive guide.

How to use golf rangefinder monocular

In Layman’s term, a monocular is a binocular cut into two pieces. The lens has specially marked lines which help determine the distance to the hole from the ball. Gauging the distance helps you choose the most appropriate club to use.

When using a rangefinder monocular, there are two views, namely, obstructed and unobstructed. When dealing with either of these views, you use different techniques. Unobstructed view is when nothing is standing in between the target and the ball.

On the other hand, the obstructed view is when there are other things in between the player and the target. So, how do you go about the two views? I shall break each one of them down for you below.

Unobstructed View

Unobstructed view offers an easy procedure. For instance, the first step is to stand behind your golf ball. Using your rangefinder scope, locate the flap post using the “Green” line on the scope.

Once you have found the flap stick using the “Green” line, tilt the scope to align the “Green” line to the base of the flag. This requires utmost care and precision.

When tilting the scope, ensure you align the scope in such a way that the “Green” line assumes a perpendicular position the flagstick. This is the only way you will get accurate results.

Using the scale, note the number on your scope that corresponds to the top of the flag post. The corresponding number represents the distance (yardage) from the ball to the target.

That easy!

Briefly, here are the steps for unobstructed view:

  • Stand next to the ball, ensuring that you have a clear view of the target (hole).
  • Hold the golf rangefinder monocular to one eye
  • Match the line marked “green” on the viewfinder to the bottom of the flag post
  • Read the numbers lined with the flag post top.
  • After that, choose the appropriate golf club according to the distance indicated

Obstructed View

Obstructed view poses some challenges for the user. If the base of the flag post is invisible, then you have to use a different process to identify the distance. In this case, we assume you are using a stripped flag post.

So, what do you do? Obviously, the first step is to stand behind the golf ball. After that, use the “Green” line to locate the flap post. Then match the “Green” line to the lowest visible strip of the flap stick. To match the lowest strip to the green line, you need to tilt the scope carefully.

In the next step, ensure you hold the scope in a position where the “Green” line stands perpendicular to the flag post. Failure to do so yields inaccurate measurements.

Next, take note of the grid number corresponding to the top of the flag post. The number appears on the viewfinder’s scale.

After identifying the grid number, multiply it by the number of visible strips on the flag post. Afterward, divides the answer by 8. The result after dividing by 8 represents the yardage from the ball the target (hole).


Let’s assume the top of the flag corresponds to 400 on the viewfinder scale. Then we have, say, 5 visible strips on the flagstick.

Then the distance becomes (5×400)/8 = 250 yards.

Briefly, here are the steps for obstructed view:

  • Line up the lowest stripe of the flag post with the lower line in the viewfinder scope
  • Identify the number corresponding with the flag post’s top
  • Count the number of strips to the top of the flap post
  • Multiply the of strips with the number which lines up with the flag post’s top
  • Divide the results of the above step by 8
  • The result for the step above is the distance

If you wanted to know how to use golf rangefinder monocular, then you have the two steps above. The steps explore the two possible scenarios expected when using a rangefinder scope.


When using a rangefinder scope on an unobstructed view, the steps are straightforward. However, with the obstructed view, the flag should be striped.

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.

Mostly, golf rangefinder scopes measure distances in meters or yards. So, the yardage exists in meters or yards.

Keeping your golf scope clean is a basic practice in golf. Clean it with a damp cloth after every use. Of course, you also have to blow out any dust off the scope and lenses.

In Summary

Throughout my career as a golfer, I have faced several hurdles. For instance, learning how to use golf rangefinder monocular wasn’t a walk in the park. However, I managed, and you can do it too.

I have broken the entire process into an effortless and straightforward procedure. With a little practice, you will be there! Stick around for more golfing tips and tricks.

Till next time, bye!
