The Tank-Panzer made by Millennium Golf Discs was PDGA Approved on 8-29-2013.
"The Tank-Panzer was designed to compliment the original Tank. It's the more stable version with the same chain blasting profile and an extra wide patented thumb track grip. It still holds a line when thrown into a headwind and is great for putting on windy days. Tank lovers who want more control with less effort, will fall in love with the Tank-Panzer." - by Millennium Golf Discs
