Our stake is designed to allow or limit decoy motion depending on the circumstances. Our turkey stakes come with two grommets on the stake that can be used in several configurations. There are three ways you can control the motion with this system, depending on what you want. 

Little to No Wind | You can use the stake without grommets (just push the grommets lower on the stake so they don't touch the decoy. This allows the decoy to move in light wind. 

Wind | In Higher wind raise the grommets on the stake so that the decoy sits on them. The friction between the decoy and the grommet keeps the decoy from spinning. 

High Wind | In really high wind, you can actually push the grommets up inside the motion tube. This make the decoy so that it won't move at all.
