The Millennium Quasar is built for strong throwers and shots needing a dependable disc to finish with a strong fade. It is our most over-stable disc providing players with confidence when throwing against the wind. This disc is a great choice for both backhand and sidearm throwers. Zero-G technology incorporates thousands of microbubbles into our durable Quantum plastic. This results in high speed, premium plastic drivers in weights all the way down to 130 grams! Testing indicates that models under 140 grams are light enough to float in water!
