This is a classic and very popular call for large predators.
It imitates the cry of a hare.

It is highly effective for attracting foxes and other larger predators, even from long distances.
It is easy to use and very durable, which allows for long-term use.
Very realistic sound!!!!!

The adjustment and modulation of the sounds produced have a major impact on hunting results. By varying the sounds, you improve your chances of success. Imagine a hare in danger. Its high-pitched cries should be full of emotion, which will spark the predator’s interest. Remember not to call continuously.
You should take longer breaks between calls in order to realistically imitate the cry of a hare. Start with quiet calling, because you never know how close the predator may be.
If there is no interest, gradually increase the intensity of the calling.
