Just attach to the bottom of the decoy with two zip ties, and clip the weight of your choice to the ring on the retriever. Pull the amount of cable out of the retriever according to the depth of water you are in, and just toss them out. When you pick them up, just give the decoy a jerk upward, and the weight retracts back into the retriever. Even if there is muck or weeds on the weight and cable, it will retract.
