                                    Airfast, small, high-pitched plastic whistle, 117 decibels, no rattle. It has three chambers and produces two extremely high frequency sounds and one lower frequency. This combination makes it effective in close as well as distant training. Extremely loud in the human ear, which is an advantage for some dog breeds. It’s tapered at the mouth.
