ACME Combination Whistle No. 642 | Thunderer Whistle and Single Whistle in one unit | Includes Whistle Band for Hanging (No. 211.5 + No. 560)

• Tones: combination whistle from the single whistle and a trill tone. This type of whistle (double tone whistle/combination whistle) is particularly popular with hunting dogs and working dogs.
• Use: In most cases, the whistle is used as a call back command and the trill sound as a down signal, i.e. the dog should sit down or lie down and wait.
• Frequency standardised: the tones of this model are completely frequency standardised and can be reordered at any time. It can either be reordered the combination whistle or the individual tones such as a separate whistle or triller.
• Extensive: the sounds are particularly loud and far-reaching, so your pet can hear the sounds well even at a long distance and perceive them
• Weather-resistant: this whistle always produces the identical sound. No matter what weather conditions. It can rain, hail or storms, your dog will always receive the same signal. Even the trill ball cannot get jammed with this whistle and can therefore always be used.

If dog whistles were used in the past, especially for hunting dogs, signal whistles have become an integral part of the crowd of home dog owners in recent years. A whistle allows easy contact with the dog over long distances and in disturbing environmental conditions (wind, leaf noise). The respective signal sounds loud and clear and, as often with verbal commands, is not overlaid by the emotional position of the dog manager (anger, fear, anger). The Acme dog whistles are made of plastic and frequency standardised. Each whistle is stamped with an embossed number, which represents a specific tone or frequency. No overblowing possible - the ball cannot get stuck. Whistle 642 - a combination of whistle no. 560 and single whistle no. 211. Whistle 643 – a combination of whistle no. 560 and single pipe no. 210.
