Has anybody done that yet?


That's seems like a good idea. However, an issue I'm seeing is that some whistles may be preferable in certain environments, while others in different environments. For example, perhaps the higher frequency of a Fox 40 will cut through trees better, while a lower frequency of a Storm Whistle will sound louder on the open water. Perhaps a pea is preferable in certain environments. Who knows? Anyway, a comprehensive test in a wide array of different environments would be interesting to read.
