ACME Plastic Whistle 212 black

Original ACME PRO TRIALLER 212 whistle made of lightweight material, useful for dog training.

Medium Pitch, a great all-rounder with a sound well within human hearing range.
This special whistle maintains its frequency no matter how loudly you blow. Your dog will always know it’s their whistle. Known as the Pro-Trialler, it creates less confusion for your dog, especially at a distance or if you blow hard when your dog becomes disobedient or goes off course during a trial.
This whistle is particularly good at a distance and works very well with Pointer, Setter, Retriever, Labrador, and most Terriers.
A great whistle for harder-to-train dogs and heavy cover situations.
