"Silent" dog training whistle that is precision made, professional quality with an adjustable pitch.
Dogs can hear sounds that are inaudible to the human ear. The higher sound frequency produced by this whistle will enable you to train your dog to obey your commands. Please note that this whistle is not completely silent to the trainer.
It is very important to use the same pitch and frequency each time so your dog will learn to recognize your call. You may adjust the pitch to your dog's hearing by loosening the locking nut and turning the adjusting screw. The black plastic sleeve must be removed to adjust the pitch, but can be replaced for normal use. Decide the proper pitch by observing the responsiveness of the dog over the distance which the signal is to be sent. Dogs should be able to hear this sound up to 400 yards; however, this may depend on the direction and strength of the wind.
After you have found the right pitch, use the locking nut to keep the adjustment screw in place. Always blow with a sharp, dry breath and use the same note every time to teach your dog to recognize your call.
Made in Germany
Please note that your dog must be trained to obey whistle commands in the same manner as when they are taught voice commands or hand signals. Your dog will not just automatically come when the whistle is blown without training.
