GEMINI's SRT Spring compresses during the throw-in, reducing the stretch in the line, helping to maintain the snoods' original length, throw-in after throw-in. In addition, the SRT Springs keeps the hook under optimal tension in the bait clip during casting and provides a dynamic release! These springs are easy to apply when making rigs and prevent the bait from coming loose prematurely during casting. Anglers can use these springs on multiple or a few clamped on or off rigs and are extremely reliable. Each pack contains 10 SRT Spring set-ups (SRT Springs, Beads and Crimps).
