A propeller keel designed to fit the most popular removable-keel decoys. Simply remove the original weighted keel from the decoy and slide the Explorer inside the rail to secure. It only takes a couple to complete your spread. Uses one AA battery (not included).
I've used these for several years now. Just bought two more for this season. I've only had one that broke and it was likely in the decoy bag when the propeller and rudder broke off. I use AA rechargeable and they last several hours while hunting. I recommend attaching a swivel between decoy and string b/c string will tangle after hours of circling.
