COA High Frequency Whistle

The COA High Frequency whistle produces a high pitched sound that is clearly audible to your dog but is much quieter to humans, making it the perfect choice for people with sensitive ears or for training indoors. The high pitched sound travels well in open spaces and the pitch can be adjusted to suit individual dogs hearing ranges and provide a customized recall for your dog.
