As the weight slides to the decoy, they can be easily tossed into place with precision and without the line wrapping around the decoy. Once afloat, the weight then slides down to rest on the bottom. You can carry your decoys on the provided spring clip and never have to wind and unwind the decoy line and stuff your "deeks" in a bag. These are the fastest, easiest, and most trouble free and tangle free decoy anchors you will ever use. 30" length with 4 oz. weights.
