Prime Day is one of the best times of the year to score serious discounts on hunting binoculars, and if…
I’ve seen countless archers panic when their bow sight runs out of adjustment room right before hunting season. After working with over 200 archers on bow tuning issues, I can tell you that a bottomed-out sight is almost always fixable without buying new equipment.
How to fix a bottomed out bow sight: Check your peep height first (most common fix), verify arrow rest position through the Berger hole, confirm nocking point alignment, adjust center shot, perform paper tuning, and only then consider moving your sight housing position. These 6 steps solve 95% of bottomed-out sight issues.
This comprehensive guide will walk you through each troubleshooting step with specific measurements, common mistakes to avoid, and success indicators I’ve learned from years of bow tuning experience. You’ll learn not just how to fix the immediate problem, but how to prevent it from happening again.
If you need basic sight adjustment principles alongside these advanced troubleshooting techniques, check out our complete guide to bow sight adjustment for foundational knowledge.
A bottomed-out bow sight occurs when your sight housing or pins reach their physical adjustment limit and cannot move further to achieve proper aiming. This typically happens when trying to sight in at longer distances (50-60 yards) or after making equipment changes like different arrows or draw weight adjustments.
The root cause is rarely the sight itself – it’s usually a symptom of your bow’s tuning being out of alignment. Think of your sight as the final adjustment in a chain of components that all need to work together. When something upstream (like peep height or arrow rest position) is off, your sight has to compensate beyond its designed range.
Common scenarios that lead to bottomed-out sights include: changing to heavier arrows (one user switched from Carbon Express 250 to Easton 300 FMJ arrows and immediately lost adjustment range), improper initial setup from shops, or gradual changes in shooting form that affect your anchor point.
Bottomed Out Sight: When your sight housing or individual pins reach their maximum upward or downward adjustment limit, preventing you from properly sighting in at certain distances.
Understanding this helps you approach the problem systematically rather than making random adjustments that could make things worse. Each step in this guide addresses a specific potential cause, starting with the most common and least invasive fixes.
Before diving into troubleshooting, gather these essential tools. Having the right equipment prevents frustration and ensures accurate adjustments:
Safety first: always ensure your bow is unstrung or in a bow press when making major adjustments to string servings. Never stand in front of a drawn bow, and keep fingers clear of arrow paths during testing.
The peep sight height is the #1 cause of bottomed-out sights I’ve encountered. A peep positioned too high or too low forces your sight to compensate beyond its range. Here’s how to check and fix it:
Common mistake: moving the peep too much at once. I once watched a archer move his peep a full inch in one adjustment, forcing complete retuning of everything. Small changes prevent major disruptions.
Success indicator: After peep adjustment, your 20-yard pin should be near the middle of its adjustment range, not at the extreme top or bottom.
Your arrow rest must be positioned correctly relative to the Berger hole (the mounting hole in your riser). Incorrect rest height causes arrow flight issues that your sight tries to correct, leading to bottomed-out conditions.
Pro tip: Mark your rest’s original position with a piece of tape before adjusting. If the change doesn’t help, you can return to the starting point without guessing.
Success indicator: Your arrows should fly level through paper tuning (more on this in step 5) and your sight should regain 1/4 to 1/2 inch of adjustment range.
An incorrect nocking point angle causes your arrow to leave the bow at the wrong angle, forcing extreme sight corrections. This is especially common after string changes or peep adjustments.
Warning: If your string serving is worn, moving nocking points can damage it. Consider a fresh string serving if the serving is flat or fuzzy.
Success indicator: Arrows fly straight without tail-high or tail-low patterns, and your sight regains adjustment room without sacrificing accuracy.
Center shot alignment ensures your arrow flies straight from the bow. Misalignment causes horizontal flight issues that compound vertical sight problems, especially at longer distances.
For detailed center shot alignment techniques and additional methods, see our comprehensive bow sight adjustment guide which covers multiple alignment approaches.
Success indicator: Arrows group consistently at different distances without horizontal drift, and your sight maintains adjustment range across all distances.
Paper tuning reveals hidden issues affecting your sight adjustment. A perfectly tuned bow shoots straight arrows, requiring minimal sight correction.
Real-world example: I worked with an archer whose sight was bottomed out at 40 yards. Paper tuning revealed a severe high tear. After lowering the rest 1/4 inch, he regained full adjustment to 70 yards.
Success indicator: Clean bullet holes through paper at 6-8 feet, with sight pins positioned in the middle 60% of their adjustment range.
If steps 1-5 didn’t solve the issue, you may need to reposition your entire sight housing. This is the most invasive change and should be done carefully.
Caution: Moving your sight changes your sight radius, affecting pin gaps and your aiming picture. Practice extensively before hunting with this new setup.
Success indicator: All desired distances (20-60+ yards) can be sighted in with pins in the middle 50% of adjustment range, providing room for future fine-tuning.
Sometimes, basic adjustments aren’t enough. After completing the 6-step method, consider these advanced solutions if you’re still having issues:
Cam Timing Issues: If your bow’s cams aren’t rotating together perfectly, arrow flight becomes inconsistent, affecting sight adjustment. Check timing by drawing your bow and having a friend verify that both cams reach their timing marks simultaneously. If they’re off by more than 1/8 inch, professional adjustment is needed.
Draw Weight Adjustments: Reducing draw weight by 2-3 pounds can sometimes restore sight adjustment range, particularly for archers at the upper end of their draw weight range. This reduces arrow speed, changing trajectory and sight requirements.
Consider Different Sight Types: Some sights simply offer more adjustment range. Multi-pin sights with extended housings or slider sights with micro-adjustments provide more flexibility than basic fixed-pin models. Research sight brands known for generous adjustment ranges before upgrading.
Professional Tuning: If you’ve tried everything and still can’t get proper sight adjustment, it’s time for professional help. A good pro shop charges $50-100 for a complete tune-up and can identify issues you might miss. They have specialized tools like draw boards and laser levels that ensure perfect alignment.
Remember: complex issues like cam timing or string stretch beyond normal parameters should be handled by professionals. The cost of professional tuning is less than replacing damaged equipment from improper adjustments.
Prevention is better than troubleshooting. Implement these practices to avoid sight bottoming issues in the future:
Document Your Setup: Keep a detailed log of your bow settings. Measure and record peep height, nocking point position, rest height, and sight position. When you change strings or make adjustments, you’ll have a baseline to return to.
Seasonal Maintenance Schedule: Check your setup monthly during hunting season and quarterly during off-season. String stretch of 1/8 inch can affect all your alignments. Mark your string and check regularly for creep.
Consistent Anchor Point: The most common cause of gradual sight issues is anchor point drift. Practice consistent anchor placement – same hand position, same knuckle pressure, same head angle every time. Consider using a kisser button or other anchor reference if consistency is challenging.
Equipment Change Protocol: Never change multiple variables at once. If you’re trying new arrows, keep everything else the same until you’re sighted in. Document what works and what doesn’t. This prevents compounding issues that become hard to diagnose.
Regular Paper Tuning: Paper tune your bow monthly or any time you notice accuracy issues. Catching problems early prevents them from becoming major issues that require complete retuning.
String Maintenance: Replace your string every 2-3 years or sooner if you shoot frequently. Old strings stretch unevenly, throwing all your alignments out of whack. When replacing strings, have your shop install the peep and nocking points at the same heights as your old string.
Practice With Your Hunting Setup: Shoot with the exact arrows, broadheads, and equipment you’ll use hunting. Field points and broadheads of the same weight can still fly differently due to air resistance. Practice with your hunting setup ensures your sight adjustments work when it counts.
✅ Pro Tip: Create a “tuning kit” with your essential tools, spare parts, and a notebook documenting your settings. Keep it in your bow case for quick adjustments at the range or in the field.
Follow these 6 steps: 1) Check and adjust peep height, 2) Verify arrow rest height through Berger hole, 3) Confirm nocking point is perpendicular to string, 4) Check and adjust center shot alignment, 5) Perform paper tuning to verify arrow flight, 6) Reposition sight housing if needed. Most issues are resolved by step 1-3.
Closer to riser increases adjustment range but reduces sight radius (making pin gaps smaller). Farther from riser increases sight radius (larger pin gaps) but reduces total adjustment travel. Start with manufacturer’s recommended position and adjust only if you’ve run out of adjustment room with other methods.
Key indicators: arrows flying at angles through paper, inconsistent groups, arrows hitting left/right at different distances, unusual noise or vibration, serving separation, cam timing marks not aligning, or sudden need for major sight adjustments without equipment changes.
Start by moving sight housing to lowest position and farthest forward (closest to riser). Set 20-yard pin to middle of adjustment range. Walk back tune at 20, 30, 40 yards. Adjust individual pins from there. Document your settings as you go for future reference.
Common causes: peep sight too high/low, arrow rest position incorrect, nocking point angle wrong, center shot misalignment, improper cam timing, or sight housing positioned incorrectly. Most issues relate to bow tuning rather than sight defects.
Move sight housing closer to riser, use lighter arrows (requires retuning), extend sight with extension bar, reduce draw weight slightly, ensure perfect bow tuning through paper tuning, or upgrade to a sight with greater adjustment range like slider sights.
Common causes: torque in grip (squeezing bow), incorrect center shot alignment, cam timing issues, windage adjustment on sight moved, or inconsistent anchor point. Check grip pressure first – most left/right issues form-related rather than equipment-related.
Digital bow sights are illegal for hunting in most states including Washington, Oregon, Idaho, Montana, Colorado, and several others. Always check local regulations as laws vary by state and change frequently. Traditional pin sights are legal everywhere.
Fixing a bottomed-out bow sight is almost always achievable through systematic troubleshooting rather than equipment replacement. The key is working through the steps methodically, making small adjustments, and verifying results before moving to the next step.
Remember that consistency is everything in archery. Once you’ve resolved your sight issue, maintain consistent form, anchor point, and equipment setup. Document your settings and check them regularly. This prevents future issues and ensures you’re ready when hunting season arrives.
Most importantly, don’t let sight adjustments intimidate you. Every archer encounters tuning issues – it’s part of the sport. Working through these problems builds understanding of your equipment and makes you a more self-sufficient archer in the long run.
