The Gemini Spring Loader Bait Tool is designed to package both single and cocktail baits into tight, well-formed, robust packages with minimum effort or skill required. As the name suggests, it incorporates a unique spring mechanism within its design to ensure the bait is wrapped tightly. The two-pronged, sprung design allows you to thread bait onto the prongs or simply place the bait in the palm of your hand between the two prongs, insert the hook onto the tool and begin wrapping. As you wrap the bait, everything begins to tighten courtesy of the spring mechanism. Upon completion, unhook the hook and slide the bait off, and feel everything tighten up. The Spring Loader is produced using marine grade stainless steel to ensure quality and corrosion resistance. How does it work? Because the sprung mechanism is always pushing out against the elastic being wrapped around the tool and bait, the elastic becomes "loaded" as it is wrapped around, stretched out to its maximum and wanting to return to its shorter natural state given the chance. Loading the elastic around the bait and tool means that once the wrapped bait is removed from the tool, the constraints of the tool — two sprung loaded prongs — are no longer present to keep the elastic stretched out, causing the elastic to tighten up around the bait in an attempt to return to its original shorter length. - Comes in a pack of 2 (one medium, one large)
