All Livingston Lures are water activated. The contact points are the eyelets that hold the hooks. Whenthe lure comes in contact with water, it completes the circuit between both eyelets and activates thelure. 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 listento the sound of a distressed Shad, or crawfish one of nature’s  most sought after forage fish, minnows, croakers, mullet and  more. The sound the lure emits is located on the package nearthe UPC code on the back. If there isn’t a sound there, your lureemits EBS Original sound which is the distressed Shad. Whileit may sound like a chirp to us, to a predator it sounds like adinner bell.
