Elevate your tube fly patterns with the Pro Sportfisher Ultra Sonic Disc—a meticulously engineered component designed to enhance both form and function. Crafted from metal, these discs add a subtle amount of weight, aiding in achieving the desired sink rate without compromising castability.

The disc's unique vented design creates a vortex in the water, preventing soft materials like marabou or Finn Raccoon from collapsing in fast currents, thereby maintaining a lifelike profile and movement. The vent holes also facilitate easier lifting of the fly from the water during casting.
