In precise time-keeping “Delta-T” is a measurement, and it’s also the name of Millennium’s new baseline plastic. DT offers a super-firm feel, making it the most rigid of baseline plastics on the market. Currently offered exclusively in our popular Omega molds, beginners and pros alike now have the ability to work-in a firm version of their favorite putter. DT’s combination of grip, rigidity, and affordability is what makes it truly timeless. DT was first introduced as a fundraiser disc, then as a stock disc in July 2016.
