Nobby high-frequency whistle 5.5cm

Product detailed description

This short metal galvanized dog whistle emits a high-frequency (ultrasound-like) whistle that is less audible to the human ear. The intensity of the whistle and the frequency of the tone are adjusted by screwing the threaded piston rod secured with a hand-knurled lock nut located at the top of the hanging ring. Size 5.5 cm. Simple and effective: when training a dog with a high-frequency whistle, constant calling and scolding are a thing of the past. With a little training, your dog will understand the whistled signals as commands and will obey them. Dogs have a larger sound spectrum than humans and can hear high-frequency whistles even at a great distance and react to them. Please note that a weak whistle is sufficient and that too loud a whistle can scare the dog.
