Add random swimming action and vibration to trolling flies,soft baits and lures.
The principal of chaos...
ActionDiscs do not produce the same rhythmic mechanical action as "crankbait lip" devices or spinner blades.
As the bait is drawn through the water, pressure builds on the cupped front surface of the disc. When the pressure reaches a point of instability the disc turns to release it. This is where chaos enters in. Because the ActionDisc is perfectly symmetrical, the direction the disc tilts to dump the pressure is completely up to chance. It can go up, down, left, right or any degree from its center axis.
Once the disc decides which direction it will tilt, the tube on the back of the disc acts as a lever, bending the line in the opposite direction and pulling the front of the bait with it.
Once the water pressure is released the disc rights itself and begins again. Depending on the speed of the retrieve this process can take place anywhere from 3 times per second on a slow retrieve up to 15 times per second at a trolling speed of 4mph.
Fluorocarbon leader under 20lb test does not stand up well to constant bending caused by the ActionDisc. It has a tendency to break much like bending a coat hanger wire back and forth repeatedly.
