Was just looking through my tackle stuff , planning a trip to rayburn for 4 days next month . I came across a thing I bought from a lure company ( I won’t name ) called a predator a couple of years ago . It’s a plastic bullet - looking thing that comes with 2 weight discs . I bought the green / black model. Thought it would work good for a Carolina rig . When you submerge it in water , it gives off a low noise that is supposed to attract fish. First , to see if it worked, I put in in a glass of water . Sure enough after AWHILE , it gave off a very , very low chirping noise . So, I put it in about a gallon of water , thinking the sound would amplify . Nope. So I never put it on . I was hoping this thing would be louder than what it was but it wasn’t . Maybe the one I bought was defective ? Anyway, I learned not to pay much attention to gimmicky stuff . Anybody ever done something like I did ? …my 2cents…
