This was the Innova DX Birdie when it was first released. As several manufacturers did, this was an alternative to Destiny Disc's Super Puppy which had become a very popular putter. The Birdie was later transformed to having a "ThumbTrac". Another Innova invention. Originally produced in 1991. This disc is in pretty good condition considering. Well kept a few dings and scratches in 9/10 condition. The disc pictured is the disc you will receive.
