How to Tune Broadheads to Fly with Field Points — Bowhunter's Guide (2026)

Fixed-blade broadheads expose every flaw in tuning that field points hide. If your broadheads and field points don't group together at 30-40 yards, your bow isn't fully tuned for hunting — no matter what your paper tune looked like.

This guide covers the practical workflow for getting broadhead and field point groups to converge, with bow-specific adjustment instructions from the Sparrow Bow Tuning Wizard.

Why broadheads expose tuning flaws

Fixed-blade broadheads have wide stationary blades that act like wings during flight. Any small yaw or pitch coming off the rest gets AMPLIFIED by the blades into wider drift. Field points have no wings, so they smooth over minor tune flaws and "forgive" small errors. If fixed-blade BH and FP group together, your tune has zero residual dynamic error.

Before broadhead tuning, prerequisites

  • Bow has passed paper tune (clean bullet hole at 6-8 ft)
  • Bareshaft groups touch fletched group at 15-20 yards
  • Walk-back tune passes (all distances land on one vertical line)
  • Spin-test all broadhead arrows — even 0.005" of ferrule wobble will throw the test
  • Same point weight between FP and BH (within ±5 grains)

The procedure

  1. Set up a high-density broadhead-rated target at 30-40 yards. Standard bag targets won't survive fixed blades.
  2. Shoot 3 field-point arrows at the bullseye. Note group center.
  3. Shoot 3 broadhead arrows at the SAME aim point. Compare BH group center to FP group center.
  4. If they overlap — your bow is hunting-tuned. Done.
  5. If they don't, fix per the direction of the BH miss.

Fix recipes by BH miss direction

BH lands HIGH of field points

  • Move nocking point UP, OR move rest DOWN
  • Advance the TOP cam (twist top cable end)
  • Delay the BOTTOM cam (untwist bottom cable end)
  • Re-verify bareshaft at 20 yards before retesting BH at 40

BH lands LOW of field points

  • Move nocking point DOWN, OR move rest UP
  • Advance the BOTTOM cam (twist bottom cable end)
  • Delay the TOP cam (untwist top cable end)

BH lands LEFT of field points (RH shooter)

  • Move the cam RIGHT (yoke-twist toward shooter-right)
  • Twist the RIGHT yoke / untwist the LEFT yoke
  • Move the rest LEFT (toward riser)

BH lands RIGHT of field points (RH shooter)

  • Move the cam LEFT
  • Twist the LEFT yoke / untwist the RIGHT yoke
  • Move the rest RIGHT (away from riser)

What about mechanical broadheads?

Mechanicals fly closer to field points than fixed-blades and are LESS sensitive to small tune flaws. If your mechanicals miss field-point POI, your tune is unusually off — re-check center shot + cam timing before anything else.

Common pitfalls

  • Skipping the spin test — a bent BH ferrule causes the arrow to tumble. You'll think your tune is off when really it's a $20 broadhead.
  • Different point weights — a 100 gr field point and a 125 gr broadhead launch differently, and it's not just a weight difference. Going from 100 gr to 125 gr shifts dynamic spine by roughly 31 units softer on a 28" arrow — enough on its own to turn a clean tune into a tail-right miss. Match weights within ±5 gr for tuning, or rerun your spine number for the new point weight before you blame the broadhead.
  • Wind — broadhead test groups at 30+ yards are sensitive to even mild crosswind. Test on calm days.
  • Tuning without bareshafting first — broadhead tune is the final exam. If bareshaft isn't dialed, BH won't be either.
  • Trusting a "shop tune" at face value — a lot of shop tunes are a single-distance paper tune with the rest bumped until the hole looks clean. That's a band-aid, not a tune: it doesn't survive distance if cam timing, tiller, and nock indexing were never checked. Confirm walk-back and a broadhead-vs-field-point group yourself before you trust it.

Safety

Broadheads are sharp. Use a high-density broadhead-rated target (not a standard bag target — they'll destroy the bag AND your arrows). Keep blade sheaths on until you nock. Inspect blades after every shot for bending; bent blades fly wild.
