We’ve all been where you are now. Being filled with dread about how to adjust the bow draw length isn’t a good feeling. That is why we’ve covered the topic in detail.

Wondering how the bowtech draw length adjustment is done by professional archers?

The process of bowtech draw length adjustment is easy. By altering the module, you can quickly adapt the draw length. This enables one-inch incremental changes. The draw length could also be adjusted to half-inch degrees by changing the draw stop. The let-off can even be varied from 65 – 80 percent.

Do you think what we’ve covered till now is pretty good? If you think so, then you’re in luck because we’ll go deep into this.

Why Do You Need to Adjust the Bowtech Draw Length?

Adjust the Bowtech Draw Length

Launching an arrow with the optimum draw length ensures improving your capabilities as an archer. We’ve found that it does so by giving you the best chance at correct posture.

Draw length can influence the height of your projectiles. It can sometimes affect the spine of the arrow you might use. If you don’t modify your draw length initially you might’ve to replace your current arrows. Since the arrows will no longer be optimum for use.

Even just an ounce too wide or too brief of a draw length can create issues. Through multiple tests, we’ve found these issues can range from poor precision to damage.

Reducing the draw length raises the peep, forcing you to elevate your bow upwards. This will result in your realigning the peep with the visual range.

It should allow you to hit much harder. The bow will become sluggish, but you'll still need to adjust the peep downward or aim upwards. Without proper draw length you might discover that your arrows have flight problems.

Here’s How You’ll Adjust the Bowtech Draw Length

How You’ll Adjust the Bowtech Draw Length

Every contemporary Bowtech bow can just have its draw length altered without using draw length-specific modules. This functionality is made available through the Rotating Mod System. 

Necessary Components

  • 7/64 Hex Wrench
  • Blue Loctite 242
  • Bow String Serving Thread

Haven’t bought bow string serving threads before and unsure about which one to get? Well, we might be able to help. Here are some that we recommend you take a look at.

The products that we’ve recommended here have been used by us before and have been great. We know that you won’t be disappointed if you buy any of them. 

We’ve broken down everything you need to know into multiple steps. These should be easy to follow and guide you through the process:

Step 1: Note Down the Module Index

Loosen the module bolts that hold the modules to the round disks. You can use a 7/64 hex key to get it done. Take note of the module index value on the disk. Also the identifiers on the module.

Step 2:  Adjust the Module

The draw length of the bow can be potentially changed by adjusting the module. It results in a new value that aligns with the position on the disk. The minimum score belongs to the draw length configuration with the maximum draw length.

Step 3: Tilt the Module

Tilt the module so that the module pointer refers to a lesser amount. You will need to do so to increase the draw length. Shift the module so that the pointer aligns to a greater value to reduce the draw length.

Step 4: Secure the Module Bolts

Restore and secure the module bolts on each disk. Install two mod fasteners as near to the mod's edges as feasible. Insert the third mod pin midway between the first two.

Step 5: Add Threadlockers

Prior to actually restoring the threads at your wanted setting, we recommend adding Blue Loctite 242. This will keep the fasteners from slipping throughout everyday archery use.

Step 6: Inspect the Limb Mechanism

When you place the bow in a press, make sure the limb mechanism really hasn't altered. The limb mechanism should be positioned as deep as feasible on the limb fork. 

Step 7: Align the Wire with Timing Dots

On the module side of the disk, there are little deep gouges called “timing dots.” When looking at the bow the wire must be roughly aligned in between timing dots.

Now that you’ve learned to adjust draw length, you might want to shoot a few arrows. But before you get to that you need to learn to use a bow square. Through it, you can learn where to nook your arrows. This nocking point will allow you to fire arrows consistently.

Module and Post Settings

Here we have created a table that shows the module number and its corresponding draw length. Along with it, you will find the tested weight at both maximum and minimum settings. 

30  70  31
29 70 28
3 28 70 26
4 27 69 25
26 69 24
25 68 23
7 24 66 22
8 23 65 20
22 63 19
10 21  60 18
11 20 57 16
12 19 54 15
13  18 54 14
1 1/2  29 1/2  70 30
2 1/2  28 1/2  70 27
3 1/2 27 1/2  70 25
4 1/2 26 1/2 69 24
5 1/2 25 1/2  68 23
6 1/2 24 1/2  67 22
7 1/2 23 1/2  66 21
8 1/2 22 1/2  64 20
9 1/2 21 1/2  61 19
10 1/2 20 1/2  59 17
11 1/2 19 1/2  55 16
12 1/2 18 1/2  54 14

Following the above table when dealing with the module values your work will become easier. 


Question: Is a bow press required to change the draw length?

Answer: Compound bows with varying draw lengths employ separate round disks to generate variable draw lengths. In this instance, the shooter must buy the appropriate disk. Then install it in order to modify the draw length.

Question: How do I determine my ideal draw length?

Answer: Stand with your backside to a barrier and extend your arms out from the wall. Then try to assess your draw length. Take the width between the tips of your fingers and thumbs. Your draw length is calculated by subtracting 15 and dividing by 2.

Question: How essential is the length of the arrow?

Answer: The height of your arrow plays a role in choosing the appropriate rigidity for your arrow. The greater the length of your arrow, the more flexible it should be when launched. The harder your arrow is when shot, the smaller it is.

Final Words

Have we fulfilled all your expectations regarding the bowtech draw length adjustment? I sincerely hope so because this article required us to do a lot of research.
