Automatic duck decoy jerk string and method of using the jerk string to move duck decoys

A method of moving duck decoys comprising:

• installing a mounting pole in or above ground near a body of water;
• installing an enclosure having a sealable lid at a desired height on the mounting pole using a lockable mount, wherein
• an electric motor having a motor drive shaft is in the enclosure;
• a battery configured to power the electric motor is in the enclosure;
• a speed control to control a rotational speed of the motor drive shaft is in the enclosure;
• an elongated slider having a first slider end inside the enclosure and a second slider end outside the enclosure, the elongated slider is configured to move back-and-forth towards an inside of the enclosure and away from the inside of the enclosure;
• a gear system connected to the motor drive shaft to reduce the rotational speed of the motor drive shaft;
• a drive arm connected to the gear system so that when the motor drive shaft is rotated the gear system rotates the drive arm;
• a first link arm end of a link arm is rotatably mounted to the drive arm;
• a second link arm end of the link arm is rotatably mounted to the first slider end, wherein rotation of the drive shaft moves the elongated slider back-and-forth;
• and
• an off/on switch for connecting and disconnecting the power from the battery to the electric motor;
• connecting a first jerk line end of a jerk line to the second slider end;
• connecting a second jerk line end to a biasing device that biases the jerk line in a direction away from the enclosure;
• securing the biasing device in place with the jerk line taught between the biasing device and the enclosure;
• installing a plurality of duck decoys spaced-apart on the jerk line;
• and
• activating the electric motor to move the elongated slider, the jerk line, and the duck decoys back and forth, with the jerk line expanding the biasing device when the jerk line moves towards the enclosure and the biasing device contracting and pulling the jerk line in a direction away from the enclosure.
