What Is A Rangefinder Scope?

How To Use A Rangefinder Scope

A rangefinder scope is a tool used to measure the shooter’s distance and the target in shooting. It comes with a special reticle that permits you to regulate your shot for different distances.

It is an important device to have when you are in range shooting or on a hunting trip. On the physical, the outside of a rangefinder is similar to a traditional scope.

The key difference between the rangefinder scope and a traditional scope is on the inside. The special reticle found in a rangefinder scope has markings on the lower line, either in the form of lines or dots; these markings are pointers for shooting various distances.

Each marking on the reticle matches dissimilar distances. This will help to how to mount a red dot sight on a  scope.

Different companies are making rangefinder scopes which makes the tool common. Therefore, you may find some minor variations in the markings, color, and size in the reticle, which can result from the manufacturer’s designs.

How To Use A Rangefinder Scope

Knowing how to set up or adjust a rifle scope will give you accurate shots of your target. However, for a rangefinder to work effectively, you have to position it like a normal scope. Here is a step-by-step guide on how to correctly use a rangefinder scope for accurate shots.

Step#1: Zero In Your Scope

For the range markings on the scope to help you, you need to zero your scope. There are different methods that you can use to zero in your rifle. The common one involves taking sets of three shots at your target, get to know the distance between the bullseye and the shots, and alter your scope. You can redo this procedure until you constantly on target. Alternatively, you can also use a boresight to zero in your rifle scope, and this is a modern method.

Carefully and slowly change your scope to a point it is in line with the dot or marking from your laser. When adjusting your scope, ensure that the gun is in a stable position: it should not be shaky; otherwise, the alignment may go wrong.

Once you are satisfied with the matching or alignment, take two shots to ascertain that your scope zeroing has been achieved.

Step#2: Analyze The Distance

To calculate the distance between you and your target object, you will have to make a good guess of the object’s height and compare it to the scope’s measurements.

Different scopes have diverse setup measurements. In this case, we will presume that the scope’s measurement is set to that of a chest of a deer. In this setting, the measurement marks signify the regular chest dimensions of a deer as the deer’s chest covers more measurement lines the closer the deer. Normally, a deer around 200 yards away will cover about two and a half lines or markings.

Step#3: Align Your Scope Reticle

Pick your scope and start fixing your reticle on your aim. Start by adjusting the reticle upwards, allowing you to be on the appropriate distance point on the scope. The point at which you zero your scope and your rifle’s type will determine how appropriate your marker will be.

It is important to ensure that you are comfortable with the operating focus knob; this will allow you to be quick in making adjustments when you are out there. If you are capable, start practicing using a rifle scope by using a full-size deer target.
