An indicator speaker may produce a factory set alert sound or a recorded alert sound that a user records to distinguish one fishing pole from another. A user may insert the fishing line a desired amount down into the line wedge seam and the depth of insertion may change when the line is released upon the pivoting of the pivot arm. The fish bite indicator may have a drag knob to change how much line tension is required to move the pivot arm and may have a sensitivity knob that adjusts how far the pivot arm has to rotate before the indicator is activated.
