I went to the sportsman show today. There was a predetor hunting seminar. He went over what most of us know already about yotes. Noise, scent (wind) and cover. One take away was using a feather tied to a stick as a noiseless decoy. Let the wind move it. Worst a try I think. No batteries to worry about.
I’ve done the feather trick for years. Use an old arrow pushed in the ground at an angle then the lightest weight fishing line with a swivel tied on one end. Tie string to top of arrow, hook swivel in the feather and you’re good to go. It’s cheap and it works well
