Redesigned for Strength and Durability

Crafted from TPU plastic—the same material used in high-quality disc golf discs— FlexShark's design has been simplified and optimized for superior durability, without compromising on performance. This ensures the FlexShark will last for the long haul, delivering excellent results in any environment.

User-Friendly, High-Performance Functionality

FlexShark operates just like the original design: Simply place it against the disc’s rim and execute a quick, sharp forward motion. The FlexShark’s teeth will flex, and as the rim passes through, the teeth spring back into place, securely grabbing the disc. This design makes it easy to retrieve discs from water, ground, or even thorny bushes. Additionally, the fin of the FlexShark is coated with sandpaper, making it versatile enough to not only recover discs but also to remove a tear mid-round, or assist in disc adjustments. It’s a handy, multi-purpose tool always within arm’s reach.

Lightweight and Effortless Attachment

Weighing only around 20 grams, the FlexShark won’t weigh down your retriever or affect its ease of use. Attaching it is simple—no tools required.

Key Features and Technical Specifications:

  • Material: Durable, flexible TPU plastic
  • Weight: Just 20g – ultra-light, won’t burden your retriever
  • Dimensions: 7.5 cm x 5.6 cm x 1.1 cm

Important Considerations:

Disc Modification: Be aware that modifying discs (e.g., sanding) may make them non-compliant with PDGA regulations. Always check the official rules when preparing for competitions.

Temperature Sensitivity: As with all plastics, temperature can affect performance. In cold weather, warming the FlexShark between your hands before use might be necessary to avoid excessive resistance and ensure proper retriever functionality.
