Different duck call cadences are for different situations and scenarios. Knowing where you’re hunting and how ducks are using it is key to knowing what calls to use. You want it to be natural to match what ducks would hear as they approach an area. Are you on an X or are you running traffic? Is the location a food source or just a loaf? Knowing this will dictate your approach to how you’re going to call to the ducks and if you aren’t matching the scenario or environment, you might be in for a long hunt.
