Key Features of the 210.5 Dog Whistle

Frequency Range
The Acme 211.5 Dog Whistle is specifically designed with a precise sound frequency to effectively communicate with dogs. The sound frequency of the 211.5 whistle falls within the ultrasonic range, typically ranging from 5400 to 12400 Hertz (Hz).
The choice of an ultrasonic frequency for the Acme 211.5 Dog Whistle is based on the hearing capabilities of dogs. Dogs have a wider range of hearing compared to humans, and they can detect sounds at higher frequencies. While humans typically hear sounds in the range of 20 Hz to 20,000 Hz, dogs can hear sounds up to around 65,000 Hz or higher.

Sound Projection
The focused sound projection of the 211.5 whistle is beneficial during dog training sessions or when giving commands outdoors. Whether you’re training in a park, on a field, or in a noisy environment, the whistle’s powerful sound projection helps cut through background noise and distractions, ensuring that your signals are clearly heard by your dog.
This allows for better communication, improved obedience, and enhanced training results.

Weather Proof Material
We use materials that can withstand exposure to moisture, rain, and extreme temperatures. Common materials include high-quality plastics, stainless steel, brass, or nickel-plated brass.
ACME aims to maintain the whistle’s sound quality and volume. We strive to balance the need for weather resistance while ensuring the whistle produces a clear, loud sound that can be heard over distance.

Ergonomic Design
The shape of the whistle is carefully made to fit naturally in the hand, allowing for a secure and comfortable hold. The curves of the whistle align with the natural shape of the hand, reducing strain and fatigue during extended use.

Easy to use
My dog responds very nicely to this whistle. It is not a silent whistle. It is one I can hear.
JMSJR –
Not ultrasonic
Good, for some reason I thought it was ultrasonic. It’s not ultrasonic but it’s a good whistle
Nikki –
It works!
We have neighbors with multiple dogs that bark incessantly! We have spoken with them and the police so many times. We’ve been nice. We’ve been mean. It doesn’t matter. This whistle reaches all the way to their house (10 acres away) and it stops the barking every.single.time!

Alpha 11.5
Pup responds well to whistle. Great traing tool.
EGV –
Does the job
Great whistle. Soft plastic on the teeth.Should come with a lanyard though
GB –
Stick with the older version
Save your money. There is nothing “improved” about this whistle. This one does not project nearly as well as the older plain plastic version. It looks cooler, but performance suffers noticeably with new design.
Erkki Maripuu –
Great whistle, could be louder for long distance work
This is a really nice whistle with good feel. The rubber coating makes it comfortable to use. I gave 4/5 stars just because it could be louder. Don’t get me wrong, it’s still loud enough but could be a little louder.
Tracey –
Quality is worth the money
I tried some cheaper no-name whistles before trying this. There’s no comparison. This is a high quality whistle and worth the extra cost.There’s a bit of a learning curve to get the tone right, but my collie responds to this when he’s outside and I’m inside with the windows and doors closed as long as he’s within 30 feet or so. He can hear it when I’m standing in the open doorway across our 3 acres.

Não sei se é bom ou não. Talvez eu não saiba usar. Eu apito e… nada acontece.

I don’t recommend this kind of test but I lost my dog after a deer today. He normally has a great recall and has been trained to the whistle but I guess a deer in rutting season is enough to overwhelm anyone’s training. I could see on his GPS (also a good investment) that he was 3 fields and some woodland away by the time the chase ended (he is a small dog with delusions of grandeur so I guess they had quite easily outrun him) so I thought he might finally be capable of hearing me so I blew his whistle and immediately the blip started moving towards me. I kept whistling and sure enough he popped up. I was impressed with the whistle’s performance, less so with my idiot dog’s who has had all off lead privilege revoked until at least the end of rutting season. But it was a useful test of both the limits of his training and the whistle’s carrying ability, which is great.
