If you are starting into predator calling, just get a couple of mouth blown calls and go try them out. WAY cheaper than electronic calls, easier to carry, and just as effective. The only advantage to electronic calls is that you can set them up where you aren't, which makes the animals look elsewhere, but we like to hunt in pairs (just because it's fun to have company) so we will take turns calling from fairly good concealment while the other "covers" what we think are the approaches likely to be used.
