Most of the bobcats that I have called in have shown up in less than 10 minutes. It looks to me like setting up within 500 yards of a bobcat is more important than what sound you use. I have had many bobcats walk right up to my e-caller with the volume on full blast.
I think decoys work better on bobcats than they do on coyotes.
