The iconic "Green Machine" trolling lure has become a staple in big game tuna trolling. These lures can be fished single rigged, in a daisy chain, or on spreader bars. The acrylic head produces more action that standard shell squid lures. These are available in two sizes - the classic "Full Size" Green Machine, which has a total skirted length of about 11 inches, and the "Mini" Green Machine which has a total skirted length of about 9 inches.
