The LV 500 DRS has a unique deep rattle sound inside its body. This deep rattle works well for bass fishing because it mimics the sounds of natural prey, stands out in stained water, triggers reaction strikes, cuts through background noise, and attracts bigger fish. Bigger, more mature bass are often more sensitive to deeper sounds. This could be due to their experience with different prey types or their preference for a certain sound frequency that matches their natural hunting instincts.
