Golf practice
with receipts.
HyperPulse Golf Practice Lab is not the core launch sport, and it is not being positioned for live tournament swing advice. The lane is junior practice accountability: session volume, swing tempo, torso rotation consistency, and coach-ready reports from range work.
Golf tags
without fake claims.
HyperPulse Golf Tags are planned as passive RF/NFC workflow tags for club ID, tap-to-pair, glove/session labels, and coach report context. They are not swing sensors and do not measure ball flight, release, tempo, or speed by themselves.
What works now.
What waits.
Golf is possible, but the honest first version is a practice-mode body sensor, not a club-head launch monitor. Current Feather hardware is good enough for algorithm validation. A smaller Pro board makes the form factor believable.
Feather prototype
Use it for range testing on upper back, sternum, belt-line, or training garment placement. It can validate swing count, tempo, acceleration peaks, torso rotation repeatability, and session workload. It is too bulky for club mounting.
Pro board lane
The custom nRF52840 margin board is the better golf path because the device can feel closer to a thin training puck. Add magnetic charging later if golf becomes real revenue, not before validation.
Future golf-only
A true golf product eventually wants a dual-sensor architecture: one small body sensor and one club or glove/wrist IMU. That is how we get closer to club path and release timing without pretending the torso unit can see ball flight.
Marketable now.
Not fake.
Can measure
- Swing count and practice volume by session.
- Backswing to downswing tempo estimates.
- Torso rotation consistency and acceleration signature.
- Warmup load and fatigue drift during long range sessions.
- Coach/parent share reports after practice.
Do not claim yet
- Ball speed, launch angle, spin rate, carry distance, or dispersion.
- Exact clubface angle or club path from a body-only unit.
- Medical, injury, fatigue-safety, or return-to-play guidance.
- Live tournament coaching or swing advice during a round.
- Validated recruiting benchmarks before real datasets exist.
Practice lab,
not caddie brain.
USGA/R&A Rule 4.3 allows some equipment uses, including distance measuring in many cases, but restricts using devices for improper assistance during a round. HyperPulse Golf should ship with a Tournament Lock mode that disables live swing feedback and positions competition use as rule-review only.
Range and simulator practice: full swing metrics, reports, coach notes.
On-course practice: session log only, no live advice prompts.
Tournament lock: disable swing feedback during round and store data for post-round review only if allowed.
Official override: if a tournament, school, or coach disallows wearables, do not use it in play.
Who buys it.
Why they care.
Not a launch monitor.
A practice layer.
The golf market already has strong club, wrist, and shot-tracking products. HyperPulse only wins if it owns a narrower wedge: junior practice accountability across parent, coach, and athlete.
Blast Golf
Sensor-based swing metrics. More direct swing tool than HyperPulse. HyperPulse should not fight it on club metrics; it should fight on parent-coach practice workflow.
Arccos
Shot tracking and on-course insights. Strong for adult golfers. HyperPulse can be more youth-practice and coach-accountability oriented.
HackMotion / deWiz
Premium wrist and swing training tools. Higher-intent buyer. HyperPulse can be cheaper and broader, but less technical.
Build the proof
before the promise.
Feather range test: 3 juniors, 80 swings each, body placement comparison.
Validate swing detection and tempo against phone video timestamps.
Coach reads reports blind and marks which metrics are useful.
If coaches cannot explain a use case in one sentence, park golf until Pro board lands.
