So thermal is totally a learning curve and not the slam dunk that youtube makes it seem. I have seen them circle 600 yards to come down wind. So the way i do it is anticipate where they are and where they are ginna circle from. Then make sure you put a crosswind on your set. They dont wanna come from up wind.
Second, i dont use prey calls... or if i do it is RARE. Every jackwad in 4 close counties blast the same rabbit or woodpecker squealer.. the dogs learn quick to run away from that sound. I run usual coyote sounds, lone howler, or a duo and let territorial insticts bring them in. Much higher success.
I also go sit in a property and wait for a location call from a few dogs, cut the distance in half, and then do my own call mimicking what they did. They'll still circle downwind so know your farm youre hunting.
And patience. I sit MIMINUM 30 min... they are weary, and may take their sweet time before coming in.
Bobcats, i do use a prey and decoy. But only after I throw a cat growl. And when i do a prey i do a squirrel or rat or bird distress. I stay away from rabbits for the same reason mentioned above.
