To adjust the draw length on a Mission Craze bow, you’ll typically need to adjust the cam module. This involves loosening set screws, rotating the module to the desired position, and re-tightening the screws. Always ensure your bow is properly supported and follow the manufacturer’s guidelines for your specific model to maintain safety and optimal performance.
Archery is a fantastic sport that connects you with precision, patience, and a bit of nature. One of the most crucial aspects of setting up your bow for comfort and accuracy is getting the draw length just right. If your bow feels too long or too short when you pull it back, it can not only be uncomfortable, but it can also impact your shooting consistency. The Mission Craze bow is a popular choice for many archers, and thankfully, adjusting its draw length is a straightforward process. Don’t worry if you’re new to this; we’re going to walk through it step-by-step, making sure you feel confident and ready to tune your bow perfectly.
Why Draw Length Matters for Your Mission Craze Bow
Getting your draw length correct is like finding the sweet spot for your archery experience. If your draw length is too long, you might find yourself struggling to reach full draw comfortably, leading to shoulder strain and inconsistent anchor points. This can cause your arrows to fly erratically. Conversely, if it’s too short, you might not be utilizing the full power of your bow, and your shooting form can feel cramped and awkward. The right draw length ensures that you can pull the bow back smoothly, hold it steady at your anchor point, and release the arrow with consistent form, all of which are key to hitting your target accurately and safely.
Understanding Your Mission Craze Bow’s Draw Length Adjustment System
Mission Archery, known for its quality and innovation, designs its bows with user-friendliness in mind. The Mission Craze typically utilizes a modular cam system that allows for draw length adjustments without the need for a bow press in many cases. This is a huge benefit for beginners! The cam is the heart of the bow’s energy storage and release system, and its module dictates the bow’s draw length. By changing the position of this module, you effectively change how far back the string can be pulled.
Key Components Involved:
Cam Module: This is the part of the cam that you will be adjusting. It usually has markings or positions that correspond to specific draw lengths.
Set Screws: These small screws hold the cam module in place and prevent it from rotating unintentionally.
It’s important to note that while many adjustments on the Mission Craze can be made without a bow press, always double-check your bow’s owner’s manual. Different model years might have slight variations. For any adjustments that require pressing the bow, it’s best to visit a certified archery pro shop. They have the specialized equipment to safely compress the limbs and allow for adjustments that involve string or cable manipulation.
Tools You’ll Need for Adjustment
For most draw length adjustments on a Mission Craze, you won’t need a lot of specialized tools, which is great news for beginners!
Allen Wrenches (Hex Keys): You’ll likely need a set of metric Allen wrenches. The specific size will depend on the set screws on your cam module, but common sizes like 3mm and 4mm are often used.
Bow Square (Optional but Recommended): A bow square helps ensure your cam is timed correctly after the adjustment. This is crucial for consistent performance and can prevent damage to your bow.
Bowstring Wax: It’s good practice to wax your string and cables before or after adjustments to keep them in top condition.
Owner’s Manual: Your bow’s specific manual is your best friend. It will have the most accurate information for your particular model year. You can often find PDF versions on the Mission Archery website.
How to Determine Your Ideal Draw Length
Before you start turning any screws, you need to know what draw length you should be aiming for. An incorrect draw length will hinder more than help. Here’s a simple way to get a good estimate:
1. Arm Span Method: Stand with your back against a wall, arms outstretched to your sides, parallel to the floor. Have a friend measure the distance from the tip of one middle finger to the tip of the other. Divide this measurement by 2.5. This number, in inches, is a good starting point for your draw length.
Example: If your arm span is 60 inches, 60 / 2.5 = 24 inches. Your approximate draw length is 24 inches.
2. Bow Measurement Method (Once You Have a Bow): This is more accurate once you’re shooting. Have someone measure from your nocking point (where the arrow attaches to the string) to the center of your cam when the bow is at full draw. This measurement, plus a small adjustment (often around 1.75 inches), gives you the bow’s draw length setting. This is best done with an experienced archer or coach.
Important Note: These are estimates. Fine-tuning your draw length for comfort and accuracy is often done through trial and error while actively shooting.
Step-by-Step Guide: Adjusting Draw Length on Mission Craze
Let’s get to the core of it – adjusting the draw length. The Mission Craze typically uses a rotating cam module system. Follow these steps carefully.
Safety First:
Never dry fire your bow. This means drawing and releasing the string without an arrow nocked. It can cause serious damage to your bow and could injure you.
Ensure your bow is securely supported. Use a bow vise or have someone hold it firmly, or support it on a stable surface where it won’t slip.
Work in a well-lit area.
If you are unsure at any point, stop and consult a professional.
Step 1: Locate the Cam Modules
On your Mission Craze, you’ll find cams at both the top and bottom of the bow limbs. The draw length is adjusted by changing the position of the module on these cams. Typically, the model year of your Mission Craze will dictate if you adjust one or both cams and how.
Step 2: Identify the Adjustment Mechanism
Look closely at the cam. You should see a circular module that can rotate. There will be small set screws (usually two per module) that lock it into the desired position. These modules often have markings – numbers or letters – indicating the draw length settings they correspond to.
Step 3: Loosen the Set Screws
Using the correct size Allen wrench, carefully loosen the set screws on the cam module you are adjusting. Do not remove the screws entirely. You only need to loosen them enough so that the module can be rotated.
Step 4: Rotate the Cam Module
Once the set screws are loosened, you should be able to rotate the cam module. There might be a handle or a specific point on the module to grip. You may need to apply some firm pressure. Rotate it to the desired draw length setting. Consult your owner’s manual to understand the markings on your specific cam modules and to determine which setting corresponds to your target draw length.
Increasing Draw Length: Usually involves rotating the module in one direction.
Decreasing Draw Length: Usually involves rotating the module in the opposite direction.
Step 5: Align the Module with the Set Screw Holes
After rotating the module to your desired setting, you’ll need to re-align the set screw holes. The module will have notches or holes that need to line up with the holes where the set screws were.
Step 6: Tighten the Set Screws
Once the module is in the correct position and the set screw holes are aligned, carefully re-insert and tighten the set screws using your Allen wrench. Tighten them firmly and securely to ensure the module doesn’t move. Do not overtighten, as this can strip the screws or damage the cam.
Step 7: Check for Consistency (If Adjusting Both Cams)
Many bows, including the Mission Craze, have synchronized cams. If your bow has two modules that need adjustment (or if you want to be sure everything is balanced), you’ll need to ensure both cams are set to the same draw length. If you adjust one, you might need to adjust the other to match.
Step 8: Verify Draw Length and Cam Timing
Draw Length Verification: Gently draw the bow back (unloaded) to feel the draw length. If you have a bow square, this is the time to use it. Place the square against the bow limbs and ensure the cam is at the correct position relative to the string at full draw. If you’re unsure, it’s best to have an experienced archer or pro shop operator check this.
Cam Timing: Crucially, after adjusting the cam module, the timing of the cams at full draw is vital. If the cables are not pulling evenly, or if there’s a significant difference in where the cams “stop” relative to each other, it can affect performance and safety. A bow square is essential here. If the cams are out of sync, it might require further adjustments or a visit to a pro shop. The ArcheryTalk YouTube channel often has great demonstrations on cam timing and other bow tuning aspects.
Step 9: Test Fire with an Arrow
After making adjustments, the most important final step is to test fire your bow with an arrow. Pick a safe shooting range and shoot a few arrows.
Feel: Does it feel comfortable? Is your anchor point solid and repeatable?
Accuracy: How are your arrows flying? Consistent groups are a good sign that your draw length is set correctly.
Troubleshooting: If you still feel discomfort or notice inconsistencies, you may need to make minor adjustments. Sometimes, even an eighth of an inch can make a difference.
Troubleshooting Common Issues
Even with careful work, you might encounter a few hiccups. Here are some common issues and how to address them.
| Issue | Cause | Solution |
|---|---|---|
| Bow feels too long/short | Incorrect draw length setting. | Revisit Step 4 and adjust the cam module to the next increment. Shoot and assess again. |
| Cam modules won’t rotate | Set screws are too tight or something is binding the cam. | Loosen set screws further (but don’t remove). Ensure there are no obstructions. Apply a small amount of penetrating oil to the threads if needed, using caution. |
| Bow shoots erratically | Cam timing is off or draw length is incorrect. | Use a bow square to verify cam timing. Ensure both cams hit their stops simultaneously. Adjust draw length slightly if necessary. |
| String or cables fraying | Friction points, poor storage, or lack of waxing. | Check for rubbing after adjustments. Apply wax to string and cables. Seek professional help if fraying is severe. |
| Difficulty reaching full draw | Draw length too long or draw weight too high. | Reduce draw length gradually. If draw weight is excessive, adjust it to match your strength level. |
| Set screws strip or won’t tighten | Over-tightening, wrong tool, or damaged threads. | Stop immediately. Avoid forcing it. Take the bow to a professional archery shop for repair. |
Maintaining Your Mission Craze Bow After Adjustment
Once you’ve dialed in your draw length, a little bit of maintenance goes a long way to keep your Mission Craze performing its best and ensure its longevity.
Regularly Wax Your String and Cables: This protects them from the elements and prevents fraying. Apply a thin layer of bowstring wax every few months or whenever the string looks dry. You can find good quality bowstring wax from brands like TenPoint or BCY.
Inspect for Wear and Tear: Periodically check your string, cables, and cam modules for any signs of fraying, nicks, or damage. Pay close attention to the areas where the string and cables contact the cams.
Keep it Clean: A simple wipe-down with a soft cloth can remove dust and debris.
Proper Storage: Store your bow in a case when not in use. Avoid extreme temperatures or humidity, which can damage the limbs and string.
Periodic Professional Check-ups: Even if you’re comfortable with adjustments, consider having your bow checked by a professional at a local pro shop once a year. They can perform a more thorough inspection and ensure everything is in perfect working order. Organizations like the USA Archery website offer general archery equipment care tips.
Frequently Asked Questions about Mission Craze Draw Length Adjustment
Here are some common questions beginner archers have about adjusting their Mission Craze bow’s draw length.
Q1: Do I need a bow press to adjust the draw length on my Mission Craze?
A1: Generally, for most modern Mission Craze models, you do not* need a bow press to adjust the draw length. The adjustment is usually made by rotating the cam modules, which can be done with the bow held securely. However, always consult your specific owner’s manual, as there might be exceptions or specific model years that require a press for certain related adjustments.
Q2: How can I tell if my draw length is too long or too short?
A2: If your draw length is too long, you’ll likely feel strain in your shoulder and back when drawing the bow, struggle to maintain a consistent anchor point (where you bring the string to your face), and your elbow might feel like it’s sticking out too far behind you. If it’s too short, you might feel cramped, unable to get into a comfortable shooting position, and your shooting form may feel awkward. You may also find it hard to aim steadily.
Q3: What do the numbers on the cam module mean?
A3: The numbers or letters on the cam module typically correspond to specific draw length settings for that particular bow. Your Mission Craze owner’s manual will have a chart that translates these markings (e.g., “L,” “R,” 1, 2, 3, etc.) into actual draw lengths in inches. For example, “L” might mean long, and “R” might mean regular, or the numbers might indicate increments of a half-inch.
Q4: My Mission Craze has two cams. Do I need to adjust both?
A4: Yes, if your bow has two adjustable cam modules, you usually need to adjust both to the same setting to maintain proper cam synchronization. If one cam is set differently than the other, it can throw off the bow’s timing, leading to poor performance, increased vibration, and potential damage. Always ensure both cams are set to the same draw length setting.
Q5: What if I can’t get my cam module to rotate?
A5: If the cam module is stuck, ensure the set screws are fully loosened. Sometimes, a bit of firm but controlled pressure is needed. If it absolutely won’t budge, do not force it excessively. There might be an issue with the cam mechanism, or it might be a part of a system that requires a bow press. In such cases, it’s best to take your bow to a qualified archery pro shop for assessment and assistance.
Q6: How often should I check my bow’s draw length setting?
A6: You should check your draw length setting if you feel any discomfort, notice changes in your shooting accuracy, or if the bow has been stored improperly or subjected to significant stress. Once set correctly and functioning properly, it typically doesn’t need frequent adjustment unless you’re experiencing issues or lending the bow to someone else. However, it’s always good practice to give it a quick check periodically, especially before a hunting trip or a competition.
Q7: Can adjusting the draw length change the draw weight?
A7: While the primary purpose of adjusting the cam module is to change the draw length, it can also have a secondary effect on the draw weight. Typically, the draw weight is adjusted by altering the limb bolt (the bolt that holds the limbs to the riser). However, adjustments to the cam module can sometimes slightly alter the peak draw weight or the holding weight (the weight you feel when at full draw). Always refer to your manual for instructions on draw weight adjustment and ensure you stay within the bow’s recommended limits. Mission Archery also offers accessories like release aids that are crucial for consistent shooting form, which works in tandem with correct draw length.
