The Latitude 64 Keystone is a 2-speed understable putt & approach. With published flight numbers of 2 / 5 / -1 / 1, it is most often described as suited for straight, high-glide putting for low-power players, touch approach shots that land flat and sit.

Overview

The Latitude 64 Keystone is a glidey, understable putt-and-approach disc with flight numbers of 2 / 5 / -1 / 1.[1][3] It is a beadless putter with a deep rim, designed for smooth, controlled flights, easy turnovers, and gentle finishes.[1][3] Its high glide and slight understability let it fly straight at low speeds without requiring much power, which makes it a popular first putter as well as a finesse approach disc.[3] Thrown flat it drifts slightly with the turn before a mild, controlled fade; on a small hyzer it will flip up to laser-straight, and on anhyzer it holds a turning line well.[3] Disc Golf Puttheads classify it as an Understable putter.[3]

Flight numbers describe the published behavior of the disc when thrown at its design speed. Real-world flight varies with plastic, weight, age, and thrower power. The community-averaged numbers above reflect crowd-sourced observations from real throws — typically slightly more understable than the manufacturer's published values, which is the most consistent pattern across nearly every commercial mold.

The Keystone works as both a primary putting putter and a touch approach disc, favored for its forgiving high glide and workable, straight-to-turning flight rather than a hard overstable finish.[3] Lower-power players get flat, carrying flights with only a soft fade, while advanced throwers use it for hyzer-flip turnovers, line-shaping in the woods, and floaty touch shots that settle near the basket.[3] Latitude 64 offers it in grippy Zero baseline plastic (Medium and Hard firmnesses), durable premium Opto, and the Retro Burst blend.[1][2] It is best reserved for shorter, controlled forehand upshots rather than full-power sidearm drives.[3]

Best for:

  • Straight, high-glide putting for low-power players
  • Touch approach shots that land flat and sit
  • Hyzer-flip to straight or turnover lines
  • Finesse anhyzer shaping in the woods
  • Soft forehand upshots inside the circle

Plastics & variants

The Keystone is available in the following plastic blends from Latitude 64:[1]

Zero Medium, Zero Hard, Opto, Retro Burst

Plastic blend significantly affects flight character. Premium plastics like Champion, Z, or C-Line generally fly more overstable when fresh and hold their stability over time. Base plastics like DX, Pro, or Active beat in faster and become more understable workhorses with use.

History

The Keystone was PDGA-approved on January 22, 2019 under certification number 19-01.[2] It joined Latitude 64's putt-and-approach lineup as a beadless, high-glide understable option, complementing the company's more stable putters.[1][3] Latitude 64, based in Skövde, Sweden, and part of the Trilogy group alongside Dynamic Discs and Westside+Discs">Westside Discs, produces the Keystone in its Zero (baseline), Opto (premium), and Retro Burst plastics.[1][2] PDGA records list a maximum weight of 175.1g, a 21.1cm diameter, and a 1.5cm rim depth, reflecting the deep, comfortable rim that gives the disc its glidey, putter-friendly feel.[2][3] It has become a common recommendation for new players seeking an easy-to-throw straight putter.[3]
