These sound files are a combination of live geese and skilled operators running RedBone calls. Take a few minutes and compare the live bird recording with the sound that the operator is making. Realism is all that matters and the best way to know if the call is capable of sounding like the bird is to put them side by side.
If you're thinking about purchasing a new call get one that you can hear running next to a live bird. Learning to make realistic sound is all about eliminating variables. A call that is designed, built and can be shown capable of sounding alive eliminates the call as a variable in the learning curve.
The hardest thing in this world to break is a bad habit. Wasting time practicing and in the field with a call that cannot sound alive is bad enough but the habits that will develop in the struggle are hard to break. If you're considering a new call get one that you have confidence in because you have heard that it can sound alive.
