All Livingston Lures are water activated. The contact points are the line tie eyelet and the front hook eyelet. When the lure comes in contact with water, it completes the circuit between both eyelets and activates the lure. You can simulate the connection by placing your fingertips on both hook eyelets at the same time. Hold the lure close to your ear (not too close though) and listen to the sound of a distressed Shad, or crawfish one of natures most sought after forage fish, minnows, croakers, mullet and more. The sound the lure emits is located on the package near the UPC code on the back. If there isnt a sound there, your lure emits EBS Original sound which is the distressed Shad. While it may sound like a chirp to us, to a predator it sounds like a dinner bell.
