Description
I modeled this whistle after the Acme oblong dog whistles. I have printed and tested the tones. The 210.5 is the highest pitch, quietest and probably the best for indoor or close work. The 212 is very loud. I have included the scad file and you are welcome to customize the file to create the right length and pitch for you.
