535 SILENT DOG WHISTLE BRASS

No "silent" dog whistle is truly silent. You can hear it, but what your dog hears is really loud and travels up to 1.5 km. Adjustable through a wide range of frequencies and using a screw plunger mechanism that allows you to tune it to suit your own dog, this is the most versatile silent dog whistle that can be used on all dog breeds. A booklet is provided with each whistle that gives easy instructions for setting up the whistle and training your dog.
