These are brand new and never been opened! With the motion bases you simply place the base of you goose decoy on the motion base and then strape it in with the straps that are attached to the motion base. You can use feeder or uprights. The motion base rotates the decoys back and forth, making it look like the goose walking through the feild. The power necker attachs to the base of the decoy where the decoys head would normally go. Then it rotates back and forth making it look like the goose is looking around. I would be willing sale them or trade for other hunting equipment. let me know if you are interested! If you would like to buy them make me an offer. The bases retail for $99 and the power necker for $49.
Thanks! Austin
