The word anhyzer is disc golf lingo describing a right hand fade or bend in its flight path. Anhyzer discs are also referred to as under-stable and tend to side on the more under in this category. As drivers, these discs are also commonly used for straight, slow-speed, low-ceiling shots, and rollers. They can also be extremely effective to beginners, throwers with slow arm speed and less snap.
Two major characteristics control the stability of a disc: one is the mold or shape that dictates the aerodynamics, largely from the type of beveled edge and flight plate; and two is the weight of a disc. The lighter the disc is, the more under-stable that mold will be. However, the mold and shape will always be the dominant factor in determining the stability of a disc.
