All Livingston Lures are water activated. The contact points are the two brass trigger points on top of the lure. When the lure comes in contact with water, it completes the circuit between both tigger points and activates the lure. You can simulate the connection by placing your fingertips on both brass trigger points at the same time. Hold the lure close to your ear (not too close though) and listen to the sound of distressed baitfish. The sound the lure emits is located on the package near the UPC code on the back. While it may sound like a chirp to us, to a predator it sounds like a dinner bell.
