The Hammerhead Mighty M4:9 Whistle is a slightly larger version of the Hammerhead Classic and has a deeper tone and louder volume.

The Hammer Head Mighty is designed with the user's safety as a top priority. These whistles send sound forward and away from your ears, instead of sending it upward into your face and ears.

The patented design of Hammerhead Whistles creates a clearer sound that can be heard at greater distances than a conventional whistle. Plus, the Hammerhead pea is waterproof and specially designed to withstand both wet and dry conditions without freezing or jamming.

Weight: 10.2g
Volume: 125dB

Hunts. Family pet. Competes.

This is my first time to try this design whistle. My young grandson is working with me, training a dog, and I wanted a smaller yet loud whistle for him. I like the design and weight of this whistle. It is perfect for a young first time trainer, as well as a pro.
