1. A fish attraction device, comprising:
a motor;
an output shaft coupled to the motor, the output shaft configured to rotate about a rotational axis (Ar);
first and second cams rotationally coupled to the output shaft about the rotational axis;
a first thumper, the first thumper configured to move from a first downward state to a first upward state and then back down to the first downward state to create a first thumping pattern as the first cam rotates with the output shaft about the rotational axis (Ar); and
a second thumper, the second thumper configured to move from a second downward state to a second upward state and then back down to the second downward state to create a second thumping pattern as the second cam rotates with the output shaft about the rotational axis, the first and second thumping patterns collectively providing a rhythmic thumping pattern designed to attract fish.
