I'm cheap, bought a small 3lb anchor, attached a 2' bungie cord, and then tied decoy line to that. When I setup I chunk the anchor out into the middle. I then make a loop in the decoy line, flip that loop over the main line, and then wrap loop around keel of deke(s). I just youtubed homemade jerk string. I leave the weights and all just wrapped around keel as well. If you do it right when you pull it comes to you, then spins and turns the other way when released. I've yet to completely master it but it works well enough. My hardest thing is hiding the line. It wants to float. I'm thinking about attaching some weights to the line in spots that I know would be out in the water.
