Acme Silent Whistle

Back by popular demand

This Silent Dog Training Whistle is extremely high pitched so that dogs can hear it while being almost completely inaudible to humans. Dogs can hear the sound from this training whistle up to 400 yards away (direction and strength of wind may affect the distance). This precision made instrument has an adjustable pitch and measures 4″ L.

This top-of-the-line whistle is the real thing, not a cheap knock-off!
