The Millennium Standard Sentinel MF (Midrange Fade) is an overstable mid range driver. The Sentinel MF is unique among mid range drivers because its rare combination of speed and fade make it perfect for situations like low ceiling fairway drives, against the wind approaches, skip/fade up-shots and 'reverse S' approaches. It might be a little too much for newer players to handle, but better players will always want to keep the Sentinel around. It debuted in Spring of 1998 as a limited edition specialty disc golf disc. But players started to fall in love with it, and some of the players Millennium sponsored said they couldn't live without it. So in Spring of 2000 Millennium decided to make it a permanent part of the line.
When you get into a tight situation, sometimes you need that special disc to save the day. That’s when the Sentinel MF shines.
