As I researched more about it I also found another name, the double fluke rig. It is really easy to set up, you don't need a lot of fancy, expensive tackle to make this happen. You need two swivels, and two flukes or minnows to swim on the rig. On the diagram you can see that this rig is very easy to set up and it is up to the imagination on how to fish it after the cast. You attach a fixed swivel with a leader at the terminal end of your line and the second swivel (also with a leader) is simply free moving up and down the main line. This allows for the two weightless soft plastic baits to swim naturally and with slow and fast twitches they will separate and come together like two real bait fish swimming and interacting with each other.
I wanted to use this rig a few times before writing this just to see how effective it actually was. I've used it three times from the bank at my local pond with great success each day and once from the kayak, also with great results. I have experimented using a few different bait options, weighted and weightless. What I've found is the weighted baits tend to just come together and stay there during the retrieve rather than moving around erratically. I also had better success fishing it closer to the surface rather than deep with a moderate retrieve speed and small twitches. I used two Zoom flukes, weedless hooked and rigged up just like the diagram above, and this presentation is a hoot to play with in the water..
This rig was new to me and honestly it is a lot of fun to use because of the erratic and realistic nature of the rig. If you haven't heard of this before it is definitely worth trying out next time you're on the water, and even if you don't catch a fish I guarantee you'll have fun playing with it.
