The M2 was the second PDGA approved mid range disc in the Prodigy line. It was originally named the M3, but to keep stability ratings consistent, was renamed the M2. This disc is described to be extremely reliable with a stable flight path. The M2 is designed for moderate power throws that need to consistently finish to the left (for right handed back hand throws). It is a consistent flying disc for all wind conditions, especially in heavier weights. The dimensions of the M1, M2, M3, and M4 very only by a few millimeters.
