Recycled Disc Dots are old disc golf discs that have been repurposed by Trash Panda and become a putting practice aid for you.
The disc dot attaches easily to the chains in your practice basket. Just give it a little squeeze and you can attach the disc dot where you want to aim. The benefit of the dot is that it's much easier for your eyes to focus on over time versus one of those links for 10-20 minutes.
If you're serious about lowering your scores through disc golf putting practice, this inexpensive disc golf dot putting aid is exactly what you need.
Get a couple of them (in different colors) and challenge yourself to hit the blue, then yellow, then red, with your putts. Good luck out there!
