Where this club lands
The field is every driver in the database that publishes both of the chart's figures — every brand, not just Callaway.
The head half
Head option
Across every option: this club's loft from the 26th to the 92nd percentile, and length at the 88th percentile.
Head: Loft against Length
The cloud is every driver head option on record that publishes both loft and length — 2,024 of them, binned by density.
Specifications by option
What this record publishes. Across 3 options: loft, lie, length and swingweight on every one.

Head geometry doesn't change with the shaft, so it's stated once. A blank cell means Callaway did not publish that figure — we don't estimate.

This driver reads as built for a high-handicap player — our deterministic reading of manufacturer designation "big bertha" (forgiveness / draw / lightweight line). A design classification, not a rule about who may play it. How the bands are read →

- Stock shaft, built.Callaway names no stock shaft for this club on the sources we hold, so there's nothing to link.
The site is in beta and the database is still being built, so expect gaps. Know something we don't? Help us fill it in — a link to where it's published is worth more than anything else you could send.
