With a mini marker from Innova you are ready to play both for fun and in tournaments where it is a requirement that you mark your disc with a mini marker before picking it up. This mini marker from Innova complies with the tournament rules for mini markers, so you are ready to go out and play.
The driver version of Innova's mini-marker is made with a little extra weight and it can therefore be used to throw around for fun as well. The extra weight makes it fly more stable than other minis.
