Livingston Lures is a company that has been churning up the ever so bland tackle industry with their lures containing a small circuit board, battery, and speaker, emitting a "bait fish" imitating sound throughout the water. By touching the hooks or the split rings you can physically start the "bait fish" sound loop..imagine a cricket..that is what you hear. Bait fish do indeed produce sound, whether or not this is the sound they make. I've used live croakers before in salt water for Trout and they indeed croak very loadly. I believe the sound produced by these lures could imitate bait fish and entice bass but further testing is needed to validate the claims. This company could revolutionize the tackle industry.<br /><br />Follow me on Instagram: <a href="https://instagram.com/ryanjetske/" target="_blank" rel="nofollow">https://instagram.com/ryanjetske/</a><br /><br />Music By The Fischermen : <a href="http://freemusicarchive.org/music/The_Fischermen/" target="_blank" rel="nofollow">http://freemusicarchive.org/music/The_Fischermen/</a><br />...<br /><a href="https://www.youtube.com/watch?v=_Vhiv58HKaQ" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=_Vhiv58HKaQ</a>
