P.S.I. Imports Silent Acme Whistle (Carded) Psi Silent Acme Whistle Card Training & Behavioral Aids

I've had several of these over the past fifty years. They are all the same: top quality and they do their job. They may be tuned to be totally silent but that would drive me nuts. So I just tune mine for a high pitched tone I CAN hear and the dog for sure can. I use these whistles in addition to the Acme Thunderer "pea" whistles often while training so I don't disturb folks in the neighborhood. The dog soon learns to respond to either whistle.

I HAVE had trouble with one whistle not holding its setting. Otherwise these are solid and unbreakable. I have one that has been around here for at least thirty years.

High quality but you'll just HATE it when you lose one!! And, as you noticed, they ain't cheap!

I got this to try and keep my neighbors dog from barking. It didn't work at all. The dog would stop for 2 seconds then go right back to barkingI think perhaps I misunderstood the productI don't know. The dog disappeared about a month later so it worked out. It arrived in decent time and the product itself was in new condition.
