The nibbles will not increase the number of bites you get, but they will increase your catch ratio due to the fact they make the crappie hold on to the jig longer. This helps with those light bites you may never feel. I live by them and use them evry time I put a jig in the water unless the crappie are spawning and will bite and hold on no matter what. I also believe the smell they put off helps when the fish are sluggish and don't want to bite.
