Get a buddy and both of you have the primos hotdog, and challenge each other from a distance. Watch them yotes come in hot and pissed off. In areas of heavy deer traffic, use a deer in distress call and rattle a fence. A wise yote will come in for a easy meal. The call that i have had the most success with , is the primos catnip. With a closed reed it is very easy to operate, and i have never had to worry about the reed sticking in cold temps. Hope this helps.
