CoachVision

Form feedback for archers without a coach.

Film one shot from behind. Get an honest read on your alignment, draw elbow, anchor and follow-through — your form, never your gear. Stance width and your lean at anchor are a front-side read; film that angle another day.

What the coach measures

One clip, one angle — here's what each angle can read. Film the other angle another day for the rest.

Camera behind you
Trunk stillness

How much your torso angle wanders from raise to release. Read it as a check rather than a grade: a big number is a real wander, but a small one is not a certificate — you can rock at the ankles with a rigid torso and barely move this number, and every published study that tells steadier archers from shakier ones measured body sway as travel, never as an angle.

Elbow line

From behind, how far your draw elbow sits out to the side of your shoulder line at anchor. A good elbow all but disappears behind you — sideways daylight is the wing.

Elbow height

Where your draw elbow rides against your shoulder at anchor — level or a touch high is the strong slot.

Draw tempo

How long the string takes from the raise to your anchor. Smooth beats fast — this only flags a draw that’s a yank or a war.

Time at anchor

How long you lived at anchor before the shot. Long enough to settle is the whole requirement — compound archers park here, snap shooters visit. The bottom edge is the one the evidence sets: across 576 filmed arrows from a state squad, no archer aimed for under 0.56s, and the better half of that squad held about 0.7s longer than the worse half. The top edge stays wide because nobody has published how long a compound archer aims.

Head stillness

How planted your head stayed during the hold. The face is the anchor point — it doesn’t travel, the hand does.

Camera front, bow side
Stance width

Your feet compared to your shoulders during the hold. Around shoulder width, a touch open if that’s your stance — the same base every arrow.

Leg steadiness

How straight your legs stay through the shot. A settled archer’s knees barely move — a dip here means the base is working too hard.

Posture at anchor

How far your torso tilts from tall at the middle of your hold. A quiet couple of degrees is normal — a real lean usually means the bow is winning today.

Trunk stillness

Read it as a check rather than a grade: a big number is a real wander, but a small one is not a certificate — you can rock at the ankles with a rigid torso and barely move this number, and every published study that tells steadier archers from shakier ones measured body sway as travel, never as an angle.

A category the clip can't show clearly comes back blank rather than guessed — and if too much of the movement is unreadable, we hold the overall score back instead of averaging what is left.

Drills the coach prescribes

🏅 Blank-Bale Form Shooting

Stand three to five meters from a bare target butt - no target face, nothing to score. With nowhere to aim, the shot cycle itself becomes the target, and your body finally gets to feel a clean shot without the pressure of hitting anything.

🏅 Stretch-Band Draw Cycles

With a stretch band instead of the bow, draw to anchor against a wall or mirror, settle for three seconds, then let down slowly. The band lets you rehearse a high, behind-the-arrow elbow a hundred times a week without fatigue or arrows.

🏅 Mirror Anchor Checks

Draw a stretch band facing a mirror and watch only your head: it should stay tall and still while your hand travels to it. The string comes to your face - your face never goes hunting for the string.

🏅 Full-Draw Alignment Holds

Draw, anchor, and simply hold for five to eight seconds without shooting - feel the shoulders settle into one line toward the target, elbow behind the arrow - then let down under control. Holding without shooting teaches the position that shooting rushes past.

How to film it

  • Film only at a proper range with a safe backstop, from behind the shooting line
  • Phone on a tripod, portrait, close enough that you stand about a third of the frame tall, head to feet - below a sixth the clip is usually rejected
  • Whole body in frame, head to feet, for the entire shot. ONE arrow per clip - the analysis reads a single shot cycle best
  • Only the archer in frame. We follow one person per clip and pick the biggest one in it, so a coach or a shooter on the next lane can be tracked instead of you - especially if they stand where more of them is visible
  • Start recording before you raise the bow and keep rolling through the follow-through
  • A fixed camera reads your body far better than a handheld one, and head stillness and bow-arm drop are skipped entirely if the phone moves
  • 60fps if your phone has it
