Every basket you have ever putted at is descended from a DGA patent. “Steady” Ed Headrick invented the chain-and-basket target — the Disc Pole Hole, US Patent 4,039,189, filed in the mid-1970s — founded DGA in Watsonville, California in 1976, coined the term “disc golf,” started the PDGA, and then released the trademark to the sport rather than owning it. He had his ashes moulded into discs. There is no more foundational company in this game.
The Mach line is a straight ladder and the difference between models is chain count. Mach Lite (16 chains, PDGA Basic) and Mach Shift 3-in-1 are practice targets. Mach 2 Pro is 24 chains in 2 rows. Mach 5 is 24 in 3 rows, Mach 7 is 28 in 3 rows, and the Mach X runs 40 chains in 3 rows on a unified X-pattern assembly developed with touring pros. Mach 5 up are PDGA Championship level with 20–25 year warranties on hot-dipped galvanised steel.
DGA sells courses, not retail. That’s why their baskets are built to stand in a park for twenty-five years.
