M4 is an extremely reliable under stable mid range driver. It is designed for all players and flies extremely far for a mid range. The M4 will turn up when thrown hard and will then have an extremely long glide and a soft straight finish. It is a favorite of the top pros who need to throw controlled long straight shots. The M4 features Prodigy's "Easy Release Technology".

The 400G series is the regular 400 plastic with a shot of adrenaline. It is the base 400 plastic mixed with another resin that give the plastic a slightly different feel than the base 400 series. The additive also makes the disc more durable and requires more time to break it in.
