Karlie high-frequency whistle

Whistles support neutral training, as emotions are not transmitted through a whistle. Metal whistles are available in different designs: as high-frequency whistles or trill whistles. High-frequency whistles are very popular in dog training. Dogs can hear high frequencies much better than humans. A sound from this whistle is also always a clear signal, unlike a voice that always sounds different. Another advantage of using this whistle is that it causes little disturbance to the environment. The frequency is adjustable. Robust metal design.
