An open, source-attributed database of golf equipment specs. Every field on every record carries its own provenance — where the number came from, when it was observed, and whether it has been independently verified. 281 records across 10 categories, 7,193 sourced field entries.
One record per model line; variants (lofts, configurations, per-iron specs, grinds) embedded under the parent.
| Category | Coverage | Records | Sourced fields | Verified |
|---|---|---|---|---|
| Drivers | Heads with adjustability, movable weights, launch/spin characterisation, and speed-range fit. | 41 | 553 | 9 (2%) |
| Fairway woods | Including mini-drivers. Per-loft stock lengths, adjustability, characterisation. | 29 | 364 | 8 (2%) |
| Hybrids | Rescue / utility heads with loft classes and iron-replacement positioning. | 20 | 247 | 8 (3%) |
| Iron sets | Full per-iron specs — loft, lie, length, offset — for every position the OEM offers. | 40 | 1,916 | 506 (26%) |
| Wedges | Every loft / bounce / grind configuration, with structured grind characterisation comparable across OEMs. | 20 | 1,486 | 9 (1%) |
| Putters | Hosel → toe hang → stroke arc fit chain standardised across OEMs. | 31 | 901 | 13 (1%) |
One record per shaft family; weight classes (Ventus Black 5/6/7/8, Dynamic Gold R300–X300) as variants under the parent.
| Category | Coverage | Records | Sourced fields | Verified |
|---|---|---|---|---|
| Driver shafts | Aftermarket and stock families with bend profile, torque, tempo fit, and weight-class variants. | 61 | 1,098 | 10 (1%) |
| Fairway shafts | Fairway-specific families and -FW variants of driver profiles. | 13 | 190 | 5 (3%) |
| Hybrid shafts | Hybrid / utility profiles, cross-linked to their driver and fairway siblings. | 12 | 170 | 6 (4%) |
| Iron shafts | Steel and graphite iron families — taper/parallel tips, step styles, flex-weight bundling. | 14 | 268 | 10 (4%) |
Per-field provenance. Specs aren’t trusted at the record level — each field carries its own source attribution (OEM-published, OEM spec sheet, lab test, community measurement, community consensus) and verification state. A record can have a verified loft and a pending swing weight at the same time, and the UI shows you exactly which is which.
Parent-club methodology. One record per model line, with variants embedded: a driver parent carries its lofts, an iron set carries per-iron specs for every position, a wedge carries every (loft, bounce, grind) configuration, a shaft family carries its weight classes. Sibling lines (P770 / P790 / P7MC) are separate parents, cross-linked.
Standardisation layers. Where OEM language isn’t comparable across brands, the schema adds a structured layer: wedge grinds get ordinal sole/relief/camber characterisation plus cross-OEM equivalence links; putters get the hosel → toe hang → stroke arc fit chain.
Contribution. Seeded records start as pending and flip to verified against confirmed OEM citations — several record tables are already verified this way.
