Calvin Heimburg’s season-defining moment came at the European Disc Golf Festival — a clutch putt for his first Major title. Last weekend at the 2025 DGPT Championship, it was another pivotal 56-footer on Hole 15 of the final round that helped carry him to victory. Only this time, he was using his own signature putter.

The Calvin Aviar delivers the same firm, confident feel trusted by top pros for years — now with Vinny’s name on it. A Signature Edition Big Bead Aviar molded exclusively in KC Pro (just how he likes it), this putter matches Calvin’s game: clean, precise, and built for big moments.
