We can not use any electonics here.
Folks use a ton of spinners here, but they are all pull string controlled. I dont use one and kill plenty of ducks. I use a jerk cord a ton. I pull the cord and hold it back under pressure until the ducks are over head, let it go and they dekes 'swim' away from me opening up a nice hole for the real ducks to land it. Boom, dead.
I also use keel less that the bottom is recessed creating an air pocket under them. With a tiniest breeze from a fart, they dance all over the water. Plenty of motion.
If we could use electronics here, the only thing I would buy would be a remote control decoy, like a remote control boat. I would use that to just pass the time driving around and racing my hunting buddies.

I am here to relieve all ducks of their future worries.
