PuttGenius by SYNK Golf · Brand System

A precision acoustic instrument for training the putting brain.

It lives in the hole, reads the ball at the moment of truth, and returns the verdict as sound.

01The idea

Reward the brain, not the mechanics.

Forty percent of strokes happen on the green, and the brain gets no signal when it succeeds. PuttDock closes the loop: eyes on the hole, verdict in the ear, the reflex wires itself.

01StrokeEyes locked on the hole. No looking down.
02CaptureShaft and dock read speed, line, and strike point at the equator.
03VerdictA pure putt returns the reward tone. A miss returns silence.
04WireThe brain binds the motion to the reward, instantly.
05RepeatThe ball rebounds. Next rep in seconds.
02The mechanism

It reads the ball at the equator.

A pressure-sensitive collar and an accelerometer resolve where the ball crossed, how fast it was traveling, and the line it was on. Technical-graphite mode is for explanation: paper, line, and labels. Patent-notebook, not marketing.

03Sound

The verdict is acoustic.

The reward tone ranks equal to the wordmark. A singing-bowl strike at 528 Hz, a ~1.7 Hz beat shimmer, inharmonic partials, 3.2s decay. Full spec in SOUND.md.

528 Hz Pure putt. The reward, the confidence tone. Optimal pace, center cut.
417 Hz Good putt. Close. Keep going.
396 Hz Off / reset. Grounded. Re-rack.

A miss plays nothing. Silence is the negative signal. The product never punishes with a harsh sound, and the lore stays heritage, never therapeutic.

04Color

Graphite carries. Green is environment. Lime is signal.

A strict hierarchy. Break it and the brand falls back to golf-startup. Color shown as material, with the rule printed beside it.

06Components & motion

An instrument panel, not a dashboard.

Hairlines, machined corners (0-4px), flat matte surfaces. No pills, no soft cards. Motion is slow and singular: a hairline brightens, a single state changes.

Sensor states

idleDormant. Stone.
armedReady to read. White.
readingCapturing / reward. Lime, one pulse.
silentMiss. No change. The negative signal.

Controls

Join the program Read the spec Disabled

One control may carry the lime signal. Never two.

07Data & telemetry

Make rate by distance.

Thin-line, measured, mono-labeled. One lime line is you; everything else is stone. Proof reads as premium.

08Voice

Short. Declarative. Earned.

Authority without hype. The craft and the data talk; the copy stays quiet.
