• Tones: combination whistle from the single whistle and a triller. This type of whistle (double tone whistle / combination whistle) is especially popular with hunting dogs and working dogs.
• Use: In most cases, the whistle is used as a callback command and the trill tone as a down signal, so the dog should sit down and wait for the sound.
• FREQUENCE STANDARDIZED: The tones of this model are completely standardized and can be reordered at any time. You can order either the combination whistle or the individual tones such as a separate whistle or triller.
• Extensible: the sounds are particularly loud and far-reaching, so your darling can hear the sounds well even at a long distance and perceive them.
• Weatherproof: this whistle always produces the identical tone. No matter what weather conditions. It can rain, hail or storms, your dog will always receive the same signal. The whistle also cannot jam with this whistle and can therefore be used at all times.

Where dog whistles 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.
