The Prodigy 400G Series D4 is a very fast understable distance driver. It is designed for all players and flies extremely far. The D4 will flip up when thrown hard with Hyzer and finish with its long glide and gentle fade. Thrown flat and hard it will take a long turnover flight then glide out with minimal fade.
D series: these discs are extremely reliable long distance drivers. They are designed so that the flights have narrower flight paths than conventional long distance drivers. This makes them extremely consistent, more accurate and much more forgiving.
400G series is 400 plastic mixed with another resin giving it a slightly different feel. The additive also makes the disc more durable and requires more time to break it in.
