how to change draw length on compound bow

Changing the draw length on your compound bow is crucial for accuracy, comfort, and injury prevention. An improperly adjusted draw length can lead to poor shooting form, reduced accuracy, and even physical harm. This guide provides a step-by-step approach to safely and effectively adjust your bow's draw length, covering various methods and important considerations.

Understanding Draw Length and Its Importance

Your draw length is the distance from the bowstring's nock point to the point where the string reaches your anchor point. This anchor point is a consistent position on your face, neck, or shoulder where you hold the bowstring during your shot. A correctly adjusted draw length ensures proper form, maximizing your power and accuracy. Too short a draw length can strain your muscles and lead to discomfort or injury. Too long a draw length can result in a weak shot and reduced accuracy.

Methods for Adjusting Draw Length

There are several ways to adjust your compound bow's draw length, each depending on your bow's design and components:

1. Modular Cam System: The Most Common Method

Many modern compound bows utilize a modular cam system. This system allows for easy draw length adjustments by swapping out different cam modules. These modules are specifically designed for various draw lengths.

Steps:

  1. Consult your owner's manual: This is crucial. Your manual will detail the specific procedure for your bow model, including the correct cam modules and tools required.
  2. Identify your desired draw length: Determine the exact draw length you need. This is often best done by a professional bow technician at your local archery shop.
  3. Obtain the correct cam modules: Purchase the correct modules from your local archery shop or a reputable online retailer. Incorrect modules can damage your bow.
  4. Follow the manual's instructions: Carefully follow the instructions in your owner's manual to remove the old modules and install the new ones. This usually involves loosening screws, removing the cams, and carefully installing the new modules.
  5. Check the draw length: Once installed, measure your draw length using a draw length measuring device. Minor adjustments might be needed using the bow's let-off adjustment screws.
  6. Properly time your cams: This step ensures your cams are correctly synchronized. Incorrect timing can severely impact accuracy and potentially damage your bow. If you are not comfortable with this step, seek professional help.

2. Adjustable Cam System: On-the-Fly Adjustments

Some bows have adjustable cams which allow you to change the draw length without swapping modules. This typically involves turning screws or rotating rings on the cam.

Steps:

  1. Consult your owner's manual: It's essential to follow the manufacturer’s instructions meticulously for your specific model.
  2. Use the provided adjustment mechanism: Follow the manual's instructions to adjust the draw length using the designated screws or rings on the cam.
  3. Check your draw length frequently: Measure your draw length after each adjustment to ensure you achieve your desired setting.

3. Seeking Professional Help: When in Doubt

If you're uncomfortable performing these adjustments yourself, or if you have an older or less common bow model, it's best to seek the services of a professional archery technician at your local archery shop. They possess the expertise and tools to accurately adjust your draw length safely and effectively. They can also help ensure your bow's timing remains correct.

Safety Precautions

  • Always consult your owner's manual: This is the most important step to prevent damage to your bow or injury to yourself.
  • Use the correct tools: Using the wrong tools can damage your bow.
  • Never attempt adjustments while the bow is under tension: Always ensure the bow is unstrung before making any adjustments.
  • Seek professional assistance if needed: Don't hesitate to consult a professional if you are unsure about any aspect of the process.

By following these steps and prioritizing safety, you can confidently adjust your compound bow's draw length to achieve optimal performance and comfort. Remember, a properly fitted bow is essential for a safe and enjoyable archery experience.
