Disc Golf Verbiage - What is a Hyzer? Overstable or Understable?
These terms apply to characteristics of your discs and will affect the flight path. However there are three areas that all come into play when throwing a disc. Stability, Angle, and Flight Path. We will detail how these all come into play below.
Disc stability is best described as a spectrum, with overstable on one end, understable on the other, and neutral in the middle. All discs on the market range in different levels of stabilities and will fly at a slightly different stability depending on your arm speed and power.
Angle of Release
Angle of release refers to the angle of the disc as it is coming out of hand during your throw. The three main angles of release are: hyzer, flat, and anhyzer. A disc can be thrown at any variation of these angles (extreme hyzer, slight hyzer, etc.) and are sometimes referred to in geometric terms (“45 degree hyzer”) or like hands on a clock (“7 o’clock hyzer”).
Flight path is the line your disc is flying on after you’ve released the disc. As stated earlier, the three main flight paths are a hyzer line, straight line, or anhyzer line. (A disc that continues to turn from a flat release can also be referred to as a turn over.)
Now that you understand the equation, you can start looking at how each combination changes the flight of the disc. If you’re a left-handed backhand thrower or right-handed sidearm thrower, simply imagine these lines as a mirror image.
Keep in mind the flight paths on the chart are a guide to how a disc would typically fly with that stability and angle of release. The exact flight paths themselves are not that important, but understanding how the angle of release and stability affect the flight path is very important.
