The idea behind this type of whistle is that it won't disturb anyone standing right there with you. A dog's hearing goes further into the ultrasonic range than a human's so they can hear these whistles.
The whistles are adjustable so that you can tune it to a frequency that gets the best response from your dog.
Produces ultra high frequencies in the range of 5800 Hz to 12,400 Hz.
This lightweight, compact whistle is ideal for dog training, both indoors and out.
Can be heard by humans (but frequencies will be out of human hearing range).
The pitch is adjustable.
Keying loop attachments.
