Silent Dog Whistle

This whistle is not a "silent" whistle. You can hear the whistle, I have tried to adjust it but it still makes noise. There are few directions on how to adjust or use the whistle. I would not buy one again. I have had it for about a month and it has been laying in a drawer most of that time. The shipping was fast.

The directions on the package say to turn the adjustment screw until an audible pitch is heard and then to continue to twist until the tone disappears. From the initial setting, I twisted the adjustment screw until it came out of the unit, and I could still not get the adudible tone to disappear, nor did the animal respond at any pitch. I found the unit not to work as decribed and threw it away.

The whistle is advertised as silent to the human ear, but it isn't. It isn't loud or piercing, and the dogs do respond to it quickly. And that's what I bought it for. It is adjusted by twisting it, which is easy.

No matter where you put the adjuster it doesn't even come close to a frequency that is inaudible to humans.

I threw it in the trash.
