Understable discs

In disc golf, the term "understable" refers to a disc's flight characteristics. An understable disc is designed to slide more to the left (for right-handed players) when thrown at a high speed and hyzer angle.

In other words, when a player throws an understable disc, it will typically fly straight and then turn to the right at the end of its trajectory. This can be useful for achieving s-curves, making double s-curves, or for getting length in the throw, especially with a lower to medium arm speed. Understable discs are often used by players who want to create length or have a safety marker for hyzer throws.

It is important to note that a disc's stability can be affected by several factors, including the player's throwing technique, arm speed, wind conditions and the condition of the disc (wear).
