Developed by AD Research, this app features 11 authentic squirrel calls that have been tried and tested by experienced hunters. With this app, you can easily produce the perfect sound to lure squirrels and increase your chances of a successful hunt.

The app comes with all the sounds you need for a successful hunt and can be used with an amplified speaker.
