About Trixie High Frequency Silent Whistle
Made from tough steel, with a lightweight and compact design, the Trixie Silent Whistle is an excellent all round whistle for both pet owners and professional trainers.
The pitch of the whistle is individually tunable, to suit your dog's needs. Silent whistles are ideal for training noise sensitive dogs. A frequency guard ensures a consistent tone to avoid confusing the dog.
The clear, strong whistle tone supports recall and other obedience training, with an ergonomic design for easy use. In order to gauge the efficiency of the whistle, it is very slightly audible to the human ear.
