histles were used earlier mainly for hunting use dogs, signal whistles have also prevailed in the mass of the house owners in recent years.
A whistle allows easy contact with the dog even over long distances and in annoying environmental conditions (wind, leaf noise).
The signal sounds loud and clear and is not superimposed by the emotional situation of the dog guide (anger, fear, anger, anger).
The ACME dog whistles are made of plastic and frequency stand-arised. Each whistle is equipped with an embossed number, which represents a specific tone or frequency.
No overinflation possible – the ball cannot get stuck.
