Before you start working on sighting your crossbow scope keep every essential tool you might need while sight your scope in front of you so that you don’t have to leave your place for every single tool while compromising your concentration.

Therefore following tools are essential you must keep in front of you while sighting in your crossbow scope.

  • Your scope-mounted crossbow
  • Instruction manual for sighting in
  • Screwdrivers for altering deflexion and elevation
  • Chronograph
  • Crossbow stand; Bipod or Tripod
  • Target sheet
  • 8-10 Arrows
  • Binoculars

So once you gather all the necessary items just get started .by going through the instruction manual at least one time so that you can better understand the following guide and sight in your crossbow scope in no time.

Initial Phase

how to see through crossbow scope
Begin these three simple steps that are featured below:

  • First thing first, you must place your target sheet almost 20 yards away from your shooting spot, a suitable distance for crossbows so that you can have optimal outcomes with this range without indulging yourself in any further hustle.
  • Then move forward towards getting your crossbow ready for shooting while cocking it carefully through a cocking device. Then put the arrow within the crossbow caliber over the shooting string.
  • Now keep your eye synced with the bullseye spot on the target sheet through the scope. Just aim for the best possible syncing with the bullseye and shoot with your finger on the trigger only, without moving your arm and hand, or else you miss.
  • Check the arrows with binoculars if they are on the target sheet then you have to go for relative adjustment if not then you must proceed to align your aim within synchronization of the red bullseye spot through altering deflexion and elevation with the screwdriver.
Once you get closer to the best possible spot on the target sheet with aiming then you just need to resolve a few inches of deviation within the deflexion and elevation of the crossbow then you are good to go.

Adjusting the Deflexion & Elevation

After attaining an average deviation within the shooting of the respective crossbow now you have to take your crossbow and screwdriver with you towards the target sheet so you can closely note the deviation margin for avoiding any malfunctioning.

For making you understand the alteration of deflexion and elevation of the crossbow we would like to proceed with an example that is as follows:

For instance, if your crossbow has shot the target sheet almost 4 inches left and 2 inches low from the bullseye then you have to retract the deflexion knob to 4 inches right while the elevation knob will be retracted 2 inches high.

Take back the arrows and get back to your shooting spot 20 yards away. Moreover, having a shooting spot almost 20 yards away from the target is quite a standard practice but a few crossbows may differ in this term. Therefore better follow the distance within the manual.


rechecking crossbow position

Here comes the time when your whole sweating will be gained with fruitful outcomes and it is the rechecking round when you have to shoot the bullseye on the target sheet while standing nor like the previous exercise where you have to shoot on the target while sitting.

First of all, keep your body posture aligned and synced with a straight orientation. You have to keep your straight and your chin must be synced with the crossbow within the most appropriate orientation.

Now shoot while standing 20 yards away from the target. Whereas  you must observe that your arrows have landed much nearer to the bullseye  though you can have the average of deviation while shooting 3-4 arrows and adjust accordingly.

Common Reason for Failure

Before we proceed further, we would like to draw your attention to the most common reason which we lack a lot while sighting in our crossbow scopes.

 It is because the hunters usually twist the knobs without counting and as a result, your deviation remains over-corrected. 

Alternative Method For Range Compensation

The most advanced and in-trend method for range compensation of a scope reticle is done by entering the actual shooting speed of the crossbow within its interface. Therefore, you must know that you cannot believe the printed shooting speed on a crossbow.

Therefore, you have to calculate it by yourself so that the range compensation must be incorporated with immense precision and accuracy. It starts with setting the chronograph and starts denoting the shooting speed.

At least shoot 4 to 5 arrows and then the average of all the shooting speeds will be the actual shooting speed of this crossbow. Now put it in the range compensation reticle and the rest will be done through the scope itself.

Why do we need to sight in our crossbow scope?

A crossbow is featured with sighting in so that the hunters don’t have to face any sort of disgrace due to missing the target despite having immaculate hunting skills, just because of deviation within target aiming.

How often do we have to sight in crossbow scope?

The crossbow scope needs to be sighted after an event of time because due to stringing, other parts within the crossbow might face minor contraction or expansion due to weather therefore the scope gets deviated. Whereas a fresh sighted crossbow may last for 2 weeks.

Can one sight in a crossbow scope with a laser?

Yes, it is possible quite in trend these days because the Sightmark Laser Boresight is becoming the easiest method for sighting in a crossbow scope. After all, it saves firing any bolts while the laser is aligned with the arrow and detects the actual deviation in real-time.

Final Words:

As you have gone through the whole guide, hope you must have understood does it works along with its different methods and the reason why it is necessary to have a well-sighted crossbow.

Whereas make it count you have to sight in your crossbow scope after 2-3 weeks even if you haven’t used it right after the last sighting in for your crossbow. But still, you have to keep a crossbow well-sighted if you want to have the best out of it.
