I don't know the answer to your question.
You'd not legally be able to use that here in Idaho (electronic callers not legal on big game).
I did have a wolf come to a coyote call. It responded to a plain old rabbit squeal.
When predator hunting, I invariably carry mouth calls in addition to the electronic call. Should I spot a big-game predator....I can use the mouth calls.
Within the shadows, go quietly.
