If you’ve been shooting the same bow for a few seasons—or even just since last year—it’s worth asking a simple question: is it still tuned the way it should be? Small issues can sneak up fast, especially after hard use in the woods or long months of storage. And at the moment of truth, even a slight tuning problem can cause a missed shot or poor arrow flight. At Grafton Archery & Outdoors , we’ve been tuning bows for decades. Our technicians handle everything in-house, from cam timing and draw weight adjustments to rest setup and broadhead tuning. Whether you’re getting ready for your first hunt or trying to tighten up groups before the season opener, here are five clear signs that your bow could benefit from a professional tune-up. Your Arrow Flight Isn’t Consistent If your arrows are grouping wide—even at short distances—it’s not always the shooter. Unstable arrow flight is often caused by timing issues, improper nock travel, or inconsistent spine reaction due to bow setup. You may notice arrows wobbling in flight, inconsistent impact points with broadheads vs. field points, or unexplained flyers during practice. All of these can point to tuning issues that need to be addressed beyond sight adjustments. Our techs check cam sync, timing marks, arrow rest position, and paper tune results to diagnose flight issues and help correct them with precision. Your Cam Timing Is Off Modern compound bows rely on precise cam synchronization to deliver smooth, accurate shots. If your cams are out of time, even slightly, it can lead to erratic nock travel and reduced performance. One sign your timing may be off is a rough draw cycle or a “hitch” near the back wall. Another is inconsistent let-off, where one shot feels completely different from the next. We use a draw board to check timing and make corrections through twist adjustments in the cables. Proper timing isn’t just about performance—it’s about confidence every time you draw. Your Strings or Cables Show Wear Your strings and cables take a beating during the season. If they’re frayed, dry, separating at the serving, or showing flat spots near the cam track, they need to be addressed. Not only does this affect safety, but string wear also causes changes in peep height, draw length, and sight alignment. We inspect string condition, check for stretch, and adjust or recommend replacements when necessary. Even high-quality strings degrade over time, especially if stored in a hot garage or left unprotected in the field. If you’re using fixed or mechanical broadheads, any change in string specs can also throw off your point of impact—especially beyond 30 yards. Your Peep or D-Loop Isn’t Consistent If your peep sight spins, shifts after a shot, or isn’t lining up when you anchor, it’s time to get it reset. The same goes for a D-loop that’s stretched out or misaligned. These may seem like minor issues, but they affect your anchor point, your sight picture, and ultimately your accuracy. A clean peep alignment should happen every time you draw. If you’re having to twist the string or adjust your face position just to see through it, something’s off. Our bow techs can realign or re-tie your peep and D-loop to match your current shooting form and sight setup, making sure everything lines up without guesswork. Your Equipment Has Changed If you’ve recently changed your arrows, broadheads, release aid, rest, or stabilizer, you need to recheck your tune. Even a small change to arrow spine or weight can impact how your bow responds under pressure. We see it every season—someone upgrades one part of their setup and suddenly they’re chasing their zero for weeks. The safest move is to have your bow re-tuned once everything is in place, before you head into the woods. We also carry products that pair well with properly tuned setups, including the G5 Megameat mechanical broadhead, the Trufire Edge FT index release, and the Ultraview UV Button thumb release—all of which benefit from exacting shot consistency.
