Since 2015, The DP has been put to the test. With steel construction, this machine has lived up to all expectations. We tried to develop the natural motion of a person pulling a jerk string to mimick what has always seemed to work, without all of the labor. With over 2 feet of pull the DP can give you any action you desire. With this design you can get movement anywhere: rolled rice, timber, sloughs, moist soil areas or any situation out there. The most realistic motion on the market. Use any jerk string you already have. Simply tie it on, and it can run all morning.
