How to Adjust Draw Length (Modular Cams) Guide 2026

Quick Answer

Adjusting draw length on modular cams involves removing the cam module from your compound bow, rotating or replacing it with a different module position, and reinstalling it with the correct Allen wrench. Most modular cam systems allow 2-4 inches of adjustment without a bow press, though some designs require professional equipment. The entire process takes 10-15 minutes for experienced archers but should be done carefully to maintain bow performance and safety.

Key Takeaways

• Modular cams allow draw length adjustment by rotating or swapping cam modules without requiring a bow press in most cases
• Proper draw length ensures your bow arm is slightly bent and your release hand anchors comfortably at the corner of your mouth
• Draw length adjustments typically range from 2-4 inches depending on the cam system, with half-inch increments common
• Incorrect draw length causes poor accuracy, shoulder strain, and inconsistent shooting form
• Most archers can adjust modular cams themselves with basic Allen wrenches and 15 minutes of careful work
• After adjustment, you must re-tune your bow including paper tuning and sight adjustments
• Pro shop adjustments cost $15-30 if you prefer professional installation
• Common mistakes include forgetting to mark cable positions and failing to verify the new setting before shooting

What Are Modular Cams on a Compound Bow

Modular cams are adjustable cam systems on compound bows that allow archers to change draw length by rotating or replacing a module attached to the cam. Unlike older cam designs that required complete cam replacement, modular systems feature a removable piece (the module) that controls where the bowstring releases during the draw cycle.

The module typically attaches to the main cam body with 2-3 screws and can be rotated to different positions or swapped entirely. Each position corresponds to a specific draw length, usually marked with letters (A, B, C) or numbers (1, 2, 3) on the module itself.

Types of modular cam systems include:

• Rotating modules: The same module rotates to different positions for various draw lengths
• Interchangeable modules: Different modules must be purchased and swapped for each draw length range
• Hybrid systems: Combine rotation and replacement for wider adjustment ranges

Most modern compound bows from manufacturers like Mathews, Hoyt, Bowtech, and PSE use modular cam technology. This design makes bows more versatile for growing youth archers, families sharing equipment, or adults whose physical condition changes over time.

Choose modular cams if you need flexibility for multiple users, anticipate physical changes, or want to fine-tune your setup without buying a new bow. Avoid them only if you’re certain your draw length will never change and prefer the slight performance edge of non-modular systems.

How Do I Know What Draw Length I Need

Your correct draw length is determined by measuring your arm span from fingertip to fingertip and dividing by 2.5, which provides a starting point that should then be verified through actual shooting. For most adults, draw length ranges from 26 to 31 inches, with 28-29 inches being most common.

Accurate measurement method:

1. Stand with arms extended horizontally, palms facing forward
2. Measure fingertip to fingertip across your chest (arm span)
3. Divide that number by 2.5 to get estimated draw length
4. Round to the nearest half-inch

For example, if your arm span is 70 inches, your estimated draw length is 28 inches (70 ÷ 2.5 = 28).

Verification through shooting form:

• At full draw, your bow arm should have a slight bend (not locked straight)
• Your release hand should anchor consistently at the corner of your mouth or jawline
• Your drawing elbow should align behind the arrow, not angled outward
• You should feel comfortable holding at full draw for 5-10 seconds

If you’re between sizes, most experienced archers recommend going slightly shorter rather than longer. A draw length that’s half an inch too short is easier to manage than one that’s half an inch too long, which causes overextension and poor form.

Common mistake: Using only the mathematical formula without testing actual shooting comfort. Your body proportions, shooting style, and anchor point preferences all affect the ideal draw length beyond simple arm span calculations.

Modular Cam vs Rotating Module Draw Length Adjustment

Modular cam systems use interchangeable modules that must be swapped for different draw lengths, while rotating module systems allow the same module to be repositioned without replacement. Rotating modules offer convenience and no additional cost, whereas interchangeable modules typically provide wider adjustment ranges and more precise half-inch increments.

Rotating module advantages:

• No additional parts to purchase
• Faster adjustment (just loosen, rotate, tighten)
• Fewer components to lose or misplace
• Typically adjusts 2-3 inches in half-inch increments

Interchangeable module advantages:

• Wider total adjustment range (often 4-6 inches)
• More precise positioning options
• Better for dramatic size changes (youth to adult)
• Can maintain multiple setups with spare modules

Performance differences: Both systems perform equally well when properly installed. The choice between them is purely about convenience versus range. If you need only minor adjustments (1-2 inches), rotating modules are simpler. If you’re setting up a bow for a growing teenager or sharing between users with significantly different sizes, interchangeable modules provide more flexibility.

Most manufacturers now favor rotating modules for flagship models because they reduce customer confusion and eliminate the need to stock multiple module SKUs. Brands like Mathews and Elite Archery have largely standardized on rotating designs, while Hoyt and PSE still offer both types depending on the bow model.

Do I Need a Bow Press to Change Modular Cams

Most modular cam adjustments do not require a bow press because the module can be removed and repositioned while the bow remains under tension. The cam module attaches to the cam body with screws that can be loosened without releasing string tension, making this one of the few bow modifications safe to perform at home without specialized equipment.

When you DON’T need a bow press:

• Standard rotating module adjustments
• Most interchangeable module swaps on single-cam or hybrid-cam bows
• Any adjustment where the module screws are accessible while the bow is strung

When you DO need a bow press:

• Some binary cam systems where both cams must be synchronized
• Bows with modules that require string removal for access
• Situations where you’re also replacing strings or cables simultaneously
• Older cam designs (pre-2010) that integrate the module into the cam body

The key indicator is whether you can access the module screws with an Allen wrench while the bow is strung. If yes, no press needed. If the strings or cables block access, you’ll need a press or a trip to a pro shop.

Safety note: Even though you don’t need a press, always work carefully. The bow is under 50-70 pounds of tension even when not drawn. Keep your face and body clear of the string path, and never remove screws that hold the cam to the axle, only the module screws.

Step-by-Step Guide to Adjusting Draw Length on Modular Cams

Adjusting draw length on modular cams requires identifying your current setting, removing the module, repositioning or replacing it, and verifying the new setting before shooting. The process takes 10-15 minutes and requires only basic Allen wrenches and attention to detail.

Tools needed:

• Allen wrench set (typically 3/32″, 7/64″, or 1/8″ depending on bow model)
• Permanent marker or tape for marking
• Bow owner’s manual or manufacturer’s online guide
• Ruler or draw length measurement tool

Step-by-step process:

1. Identify current setting: Look for markings on your cam module (letters or numbers). Note the current position and consult your bow’s manual to understand which direction increases or decreases draw length.

2. Mark cable positions: Use a marker to draw a line across the cam and module where they meet. This reference line helps you verify proper reinstallation.

3. Loosen module screws: Insert the correct Allen wrench and turn counterclockwise 3-4 full turns. Do NOT remove screws completely, just loosen enough to allow rotation or removal.

4. Rotate or swap module: For rotating modules, turn to the desired position (usually marked A, B, C, etc.). For interchangeable modules, remove the old module completely and install the new one in the correct orientation.

5. Align and tighten: Ensure the module sits flush against the cam body with no gaps. Tighten screws in a star pattern (alternating between screws) to ensure even pressure. Torque to manufacturer specifications (typically 20-25 inch-pounds).

6. Verify alignment: Check that your reference marks still align. If they don’t, the module may have shifted during tightening, loosen and reposition.

7. Test draw: Before shooting, draw the bow slowly in a safe direction to verify the new draw length feels correct. The string should reach your anchor point comfortably.

Common mistake: Tightening screws unevenly, which can cause the module to sit crooked and affect cam timing. Always tighten in small increments, alternating between screws.

For archers new to equipment adjustments, consider reading about proper draw weight selection to ensure your bow is properly matched to your abilities.

Can I Adjust Draw Length Myself or Do I Need a Pro Shop

Most archers can safely adjust their own draw length on modular cam systems with basic tools and careful attention to the manufacturer’s instructions. The process is straightforward and doesn’t require specialized equipment, making it one of the most DIY-friendly bow modifications.

You can do it yourself if:

• You have basic mechanical aptitude and can follow instructions
• Your bow uses a standard modular or rotating module system
• You have the correct Allen wrenches and your bow’s manual
• You’re comfortable working with equipment under tension
• You can verify proper installation before shooting

Visit a pro shop if:

• You’re uncomfortable working on equipment under tension
• Your bow uses a binary cam system requiring synchronization
• You don’t have the manufacturer’s specifications for your model
• You want to combine draw length adjustment with other services (tuning, string replacement)
• You’re unsure which module position corresponds to your desired draw length

Pro shop advantages: Technicians can verify proper cam timing, check for wear on other components, and perform a complete tune-up while adjusting draw length. They’ll also catch potential issues like worn strings or cable stretch that might affect performance.

Cost consideration: Pro shops typically charge $15-30 for draw length adjustment, which includes verification and basic tuning. If you plan to adjust draw length multiple times (for a growing youth archer, for example), learning to do it yourself saves money over time.

The decision often comes down to confidence and frequency. If this is a one-time adjustment and you’re nervous about working on your bow, $20-25 for professional service provides peace of mind. If you’re an active archer who tinkers with equipment regularly, learning this skill is worthwhile.

How Much Does It Cost to Adjust Draw Length at a Bow Shop

Professional draw length adjustment at a bow shop costs $15-30 for the service alone, with most shops charging $20-25 as a standard rate in 2026. This price typically includes module adjustment, verification of proper installation, and basic inspection of cam timing and string condition.

Price breakdown by service level:

• Basic adjustment only: $15-20 (module change, tightening, quick check)
• Adjustment with tuning: $40-60 (includes paper tuning and sight adjustment)
• Full setup package: $75-100 (adjustment, new strings/cables, complete tune, sight setup)

Additional costs to consider:

• Replacement modules (if needed): $20-40 per module
• New strings/cables (if recommended during inspection): $80-150
• Bow press fee (if required for your model): Usually included in adjustment price
• Follow-up tuning visit: $20-30 if needed after shooting

Most shops include the adjustment in a broader service package if you’re having other work done. For example, if you’re getting new strings installed ($100-120), they’ll typically adjust draw length at no additional charge.

Regional variation: Urban areas and specialty archery shops tend to charge toward the higher end ($25-30), while rural sporting goods stores with archery departments often charge less ($15-20). Big-box retailers like Bass Pro Shops and Cabela’s typically charge $20-25 as a standard rate.

Money-saving tip: Many shops offer free draw length adjustment if you purchased the bow from them within the past year. Ask about this policy before paying for the service elsewhere.

What Happens If My Draw Length Is Too Long or Too Short

Incorrect draw length causes poor shooting form, reduced accuracy, and potential injury, with symptoms ranging from inconsistent anchor points to shoulder strain and target panic. A draw length that’s too long forces overextension and creates instability, while one that’s too short causes cramped posture and reduced power transfer.

Symptoms of draw length too long:

• Bow arm locks straight or hyperextends at full draw
• Release hand anchors behind your face or can’t reach a consistent anchor
• Shoulder pain in your bow arm after shooting
• String slap on your bow arm or chest
• Difficulty holding steady at full draw
• Tendency to lean back to reach full draw

Symptoms of draw length too short:

• Cramped feeling at full draw with excessive elbow bend
• Release hand anchors too far forward (in front of your face)
• Reduced power and arrow speed
• Peep sight doesn’t align naturally with your eye
• Feeling “bunched up” or restricted at full draw
• Drawing elbow points outward instead of straight back

Performance impact: Studies of archery form show that even a half-inch deviation from optimal draw length can reduce accuracy by 15-20% at distances beyond 30 yards. The effect compounds at longer ranges because small form inconsistencies magnify over distance.

Injury risk: Overextended draw length is particularly problematic because it places excessive stress on the rotator cuff and shoulder joint. Archers shooting with draw length 1-2 inches too long report shoulder pain within 30-50 shots, and chronic overextension can lead to lasting injury.

Common Mistakes When Changing Modular Cams

The most frequent error when adjusting modular cams is failing to tighten module screws to proper torque specifications, which causes the module to shift during shooting and creates inconsistent cam timing. Other common mistakes include installing the module in the wrong orientation, forgetting to verify the new draw length before shooting, and neglecting to re-tune the bow after adjustment.

Top mistakes and how to avoid them:

1. Uneven screw tightening: Tightening one screw completely before moving to the next causes the module to sit crooked. Always tighten in small increments, alternating between screws in a star pattern.

2. Wrong module orientation: Some modules can be installed upside-down or backward, which dramatically affects draw length and cam timing. Always check the manufacturer’s diagram before installation.

3. Skipping the test draw: Shooting immediately after adjustment without first drawing the bow slowly in a safe direction. Always verify the new setting feels correct before nocking an arrow.

4. Ignoring cam timing: Assuming that draw length adjustment doesn’t affect cam synchronization. On some bows, changing draw length shifts cam timing and requires cable adjustment.

5. Forgetting to mark positions: Not marking the original module position before adjustment makes it impossible to return to the previous setting if needed.

6. Over-tightening screws: Applying excessive torque can strip threads in aluminum cam bodies. Use a torque wrench if available, or tighten firmly by hand without forcing.

7. Mixing up left and right cams: On binary cam systems, the modules are often mirror images. Installing the left module on the right cam (or vice versa) causes severe timing issues.

Edge case: Some older modular systems (2010-2015 models) require shims or spacers when changing draw length. Check your manual for any additional components needed beyond the module itself.

Will Changing Draw Length Affect My Bow Tuning

Changing draw length always affects bow tuning because it alters the relationship between arrow spine, cam timing, and power stroke, requiring re-tuning of paper tuning, sight pins, and potentially arrow selection. The degree of impact depends on how much you change the draw length, adjustments of one inch or more typically require complete re-tuning, while half-inch changes may need only sight adjustments.

What changes when you adjust draw length:

• Arrow spine requirements: Longer draw length increases arrow flex, requiring stiffer spine
• Cam timing: Draw length changes can shift when the cams reach full rotation
• Nocking point position: The arrow’s relationship to the rest may shift
• Sight pin distances: Longer draw length typically increases arrow speed, changing pin gaps
• Peep sight alignment: May need rotation or repositioning for proper eye alignment

Re-tuning checklist after draw length adjustment:

1. Paper tune: Shoot through paper to verify clean arrow flight (bullet hole tear)
2. Walk-back tune: Shoot at 20, 30, and 40 yards to check vertical alignment
3. Sight adjustment: Re-zero your sight pins at standard distances
4. Peep rotation: Verify peep sight aligns naturally with your eye at full draw
5. Rest position: Check that arrow rest hasn’t shifted during adjustment

How much tuning is needed:

• Half-inch change: Usually requires only sight pin adjustment (15-20 minutes)
• One-inch change: Needs paper tuning and sight adjustment (30-45 minutes)
• Two-inch or more change: May require new arrows with different spine, complete re-tune (1-2 hours)

Common misconception: That modular cam adjustment is “plug and play” with no downstream effects. In reality, draw length is one of the fundamental variables in bow setup, and changing it cascades through every other aspect of tuning.

Which Bows Have Modular Cam Systems

Most compound bows manufactured after 2012 feature modular cam systems, with nearly all major manufacturers including Mathews, Hoyt, Bowtech, PSE, Elite Archery, and Bear Archery offering modular or rotating module designs across their product lines. The technology has become industry standard because it reduces manufacturing costs and increases bow versatility.

Popular models with modular cams (2026):

• Mathews: V3X, Phase4, Atlas (rotating modules, 2-inch range)
• Hoyt: RX-8, Ventum, Carbon RX-7 (interchangeable modules, 3-inch range)
• Bowtech: Solution, SR350, Revolt X (rotating modules, 2.5-inch range)
• PSE: Levitate, Mach 1, EVO NTN (interchangeable modules, 4-inch range)
• Elite Archery: Omnia, Era, Enkore (rotating modules, 2-inch range)
• Bear Archery: Perception, Divergent, Adapt (rotating modules, 3-inch range)

How to verify your bow has modular cams:

1. Look for visible screws on the cam module (usually 2-3 screws on the outer face)
2. Check your owner’s manual for “modular cam” or “adjustable draw length” specifications
3. Visit the manufacturer’s website and search your model’s specifications
4. Look for letter or number markings (A, B, C or 1, 2, 3) on the cam module

Bows that DON’T have modular cams:

• Most compound bows manufactured before 2010
• Some budget models under $300 (fixed cam designs reduce cost)
• Certain competition-specific bows optimized for single draw length
• Vintage collectible bows from the 1990s-2000s

Buying consideration: If you’re shopping for a new bow and anticipate needing draw length flexibility, verify the adjustment range before purchase. Some modular systems offer only 1.5-2 inches of adjustment, while others provide 3-4 inches. Youth bows often feature wider ranges to accommodate growth.

How to Measure Draw Length at Home Accurately

Measuring draw length at home requires either the arm span method (dividing wingspan by 2.5) or the wall measurement method (drawing an arrow against a wall and measuring from nock to grip), with the wall method providing more accuracy for experienced archers. Both methods should be verified by actually shooting the bow and assessing comfort and form at full draw.

Arm span method (best for beginners):

1. Stand with your back against a wall, arms extended horizontally
2. Have a helper measure fingertip to fingertip across your chest
3. Divide that measurement by 2.5
4. Round to the nearest half-inch

Example: 72-inch wingspan ÷ 2.5 = 28.8 inches, rounds to 29 inches

Wall measurement method (more accurate):

1. Stand facing a wall in shooting stance
2. Hold an arrow with the nock against the wall at chest height
3. Extend your bow arm toward the wall (slight bend in elbow)
4. Position your release hand at your normal anchor point
5. Have a helper measure from the wall to the throat of the grip (where your hand sits)
6. Add 1.75 inches to account for the distance from grip to nock point

Verification through shooting:

• Draw your bow at the measured length and hold for 10 seconds
• Check that your bow arm has a slight bend (5-10 degrees)
• Verify your release hand anchors comfortably at the corner of your mouth
• Confirm your drawing elbow aligns behind the arrow
• Assess whether you can maintain the position without strain

Adjustment guidelines:

• If you feel overextended or your bow arm locks straight, reduce draw length by half an inch
• If you feel cramped or your elbow points outward, increase draw length by half an inch
• Make changes in half-inch increments and retest after each adjustment

Common mistake: Measuring with a locked-straight bow arm, which produces a draw length that’s too long. Your bow arm should always have a slight bend at full draw for stability and injury prevention.

Do I Need to Change Anything Else After Adjusting Draw Length

After adjusting draw length, you must re-tune your bow including paper tuning, sight pin adjustment, and peep sight alignment, and you may need to change arrow spine if the draw length change exceeds one inch. Additional adjustments to rest position, nocking point, and cable timing may also be necessary depending on your bow’s design and the magnitude of the change.

Mandatory adjustments:

1. Sight pins: Longer draw length increases arrow speed, which changes pin gaps and distances. Re-zero all pins at your standard yardages (20, 30, 40, 50 yards).

2. Peep sight alignment: Draw length changes affect where the peep naturally aligns with your eye. The peep may need rotation or repositioning on the string.

3. Paper tuning: Verify clean arrow flight through paper. Draw length changes affect arrow spine dynamics and may create tears that require rest or nocking point adjustment.

Conditional adjustments (depending on magnitude of change):

4. Arrow spine: Changes of 1.5 inches or more typically require different arrow spine. Longer draw length needs stiffer arrows; shorter draw length needs weaker arrows.

5. Cable timing: On binary cam systems, draw length adjustment can shift cam synchronization. Check that both cams reach full rotation simultaneously.

6. Rest position: Horizontal and vertical rest position may need micro-adjustments to achieve perfect arrow flight after draw length change.

7. D-loop length: Some archers prefer different D-loop lengths at different draw lengths to maintain consistent release mechanics.

Checklist for post-adjustment verification:

• Shoot through paper at 6 feet (should produce bullet hole or small tear)
• Verify peep sight centers naturally on your eye without head movement
• Check that all sight pins hit their intended distances
• Confirm comfortable anchor point with no strain
• Assess arrow grouping at 20 yards (should match pre-adjustment accuracy)

Timeline: Plan for 30-60 minutes of tuning work after a draw length adjustment. Rushing this process leads to poor accuracy and frustration. If you’re adjusting draw length before hunting season, do it at least 2-3 weeks early to allow time for complete re-tuning and practice.

For archers preparing for hunting season, consider how draw length adjustment fits into your broader bow season preparation routine.

Frequently Asked Questions

Can I adjust draw length on any compound bow?

Only compound bows with modular or rotating cam systems allow draw length adjustment. Bows with fixed cams (common before 2010) require complete cam replacement to change draw length, which is expensive and often impractical.

How often should I check my draw length?

Check draw length annually or whenever you notice changes in shooting comfort, form, or accuracy. Growing youth archers should check every 3-6 months during growth spurts, while adults typically need adjustment only after significant weight loss/gain or injury recovery.

Will adjusting draw length void my bow warranty?

No, adjusting draw length using the manufacturer’s specified method does not void warranty. However, improper adjustment that damages the cam or module may void coverage. Always follow the manufacturer’s instructions and torque specifications.

Can I adjust draw length in the field while hunting?

Technically yes, but it’s not recommended. Draw length adjustment requires careful attention, proper tools, and verification of the new setting. Make all adjustments at home or at the range where you can safely test and tune the bow before hunting.

How do I know which module position to use?

Consult your bow’s owner’s manual or the manufacturer’s website for a chart matching module positions (A, B, C or 1, 2, 3) to specific draw lengths. Most manufacturers also mark the draw length range directly on the cam or module.

Does draw length affect arrow speed?

Yes, longer draw length increases arrow speed because it creates a longer power stroke. Typically, each inch of additional draw length adds 8-12 feet per second to arrow velocity, assuming all other factors remain constant.

Can I adjust draw length without changing draw weight?

On most modern bows, draw length and draw weight are independent adjustments. Changing draw length doesn’t directly change peak draw weight, though it may slightly affect the feel of the draw cycle and let-off percentage.

What’s the difference between draw length and draw weight?

Draw length is the distance you pull the bowstring back (measured in inches), while draw weight is the force required to pull the bow to full draw (measured in pounds). Both must be properly matched to your body size and strength for optimal performance. Learn more about draw weight selection.

Should I adjust draw length before or after getting new strings?

Adjust draw length before installing new strings if possible. New strings stretch slightly during the first 100-200 shots, which can affect draw length by 1/8 to 1/4 inch. Set your draw length first, then install new strings and fine-tune as they settle.

Can wrong draw length cause target panic?

Yes, incorrect draw length is a contributing factor to target panic because it creates inconsistent anchor points and uncomfortable shooting positions. Proper draw length allows natural, repeatable form, which helps prevent or reduce target panic symptoms.

How much does draw length affect accuracy?

Draw length affects accuracy significantly. Even a half-inch deviation from optimal can reduce accuracy by 10-15% at distances beyond 30 yards because it creates form inconsistencies that compound over distance. Proper draw length is foundational to consistent shooting.

Do I need different arrows for different draw lengths?

If the draw length change is 1.5 inches or more, you likely need different arrow spine. Longer draw length requires stiffer arrows, while shorter draw length works better with more flexible arrows. Changes of one inch or less usually don’t require new arrows.

Conclusion

Adjusting draw length on modular cams is one of the most accessible and impactful modifications an archer can make to improve shooting comfort and accuracy. The process requires only basic tools, careful attention to manufacturer specifications, and 15-20 minutes of focused work. Most archers can successfully perform this adjustment at home without a bow press or professional assistance.

The key to successful draw length adjustment lies in proper measurement, careful installation, and thorough post-adjustment tuning. Start by accurately measuring your ideal draw length using the arm span method or wall measurement technique, then verify through actual shooting. When making the adjustment, tighten module screws evenly in a star pattern and always mark your starting position before making changes.

Remember that draw length adjustment is not a standalone modification. Plan for 30-60 minutes of re-tuning work including paper tuning, sight adjustment, and peep sight alignment. Changes of more than one inch may require new arrows with different spine characteristics to maintain optimal arrow flight.

Next steps to take:

1. Measure your current draw length using both the arm span and wall methods
2. Assess your shooting form at full draw to identify any discomfort or overextension
3. Locate your bow’s owner’s manual or download it from the manufacturer’s website
4. Gather the necessary Allen wrenches and mark your current module position
5. Make the adjustment following the step-by-step process outlined above
6. Re-tune your bow completely before returning to regular practice or hunting

For archers who feel uncomfortable making this adjustment themselves, professional bow shops offer the service for $15-30 and can verify proper installation and tuning. Whether you choose DIY or professional service, proper draw length is foundational to shooting success and injury prevention. Take the time to get it right, and you’ll see immediate improvements in comfort, consistency, and accuracy.
