The muzzle bungee or shockcord can be used either to connect the muzzle of a speargun with the shaft line, or to connect the reel line with the shaft line. Many spearos also use the bungee on their breakaway system when using a floatline. All SpearPro muzzle bungees are made in the USA with a 550lb test core. The pigtail used is 600lb test.
