Key Features of the 211.5 Dog Whistle

Sound Frequency

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

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

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

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.

Better communication

Improved Obedience, Better Communication and Enhanced Training Results

The use of a dedicated whistle like the Acme 211.5 creates a consistent and separate means of communication between you and your dog. This separation from everyday vocal cues helps to reduce confusion and reinforces the importance of the whistle as a distinct command tool. Dogs quickly learn to associate the sound of the whistle with specific actions, improving their response to training commands.

The Acme 211.5 is not silent. It is an audible to human dog whistle without the pea. The 211.5 runs about 5700 hertz and is audible to a dog at an advertised distance of 1.5 Km, or around 1600 yards. Just under a mile. I use this whistle while duck hunting. My dog hears it just fine if I need to handle on long retrieves. It is a good product that is consistent in its sound quality.

Bought more than one years ago and use it frequently with RECALL. Whistle will not make your dog stop barking simply by blowing it! (It may initially if your dog is curious, but the effect wears off quickly.) Here is how to use it for recall (barking stops if she is coming to you, by the way.)As with any whistle, it must be “primed” first by associating treats with the whistle. E.g. Feed your dog its food by hand for two days, a small handful at a time. When your dog is calm and looking to be fed, blow the whistle (I use two short bursts), say name plus “sit,” and feed part of the dog’s breakfast out of your hand. When done, praise heavily. Step away, get more of the meal in your hand, and repeat the process multiple times [3-5 whistle bursts per meal] until the food is gone. Repeat at dinner or the next morning. Usually 2-4 meal time pairings of whistle plus hand feeding of meal is enough to make the connection between the whistle and food.Next step: “prime” recall. Have high value treats ready in the house and whistle on a lanyard etc. When you catch your dog turning towards you or [better yet] coming towards you on its own, say its name plus “come” and then blow the whistle sharply. Encourage your dog as it comes to you (“come on, good girl, let’s go” etc). When she reaches you feed some of the high value treat while praising. Repeat 3-4 time inside the house per day, pairing the whistle with her name, the command, and praise. Try to catch her when she is coming to you naturally as opposed to expecting recall when she is distracted. A few days of this inside (hallways work well as she has limited places to go, except forward towards you) and when you are ready, move outside.Repeat the high reward, name, command and whistle routine outside when she is close and moving in your direction on her own. Once this working, use the recall routine when progressively further and when more distracted (e.g sniffing or eating grass etc. A few days of recall outside 4-5 time per day should get the whistle established. Be consistent and reward generously with valued treats at first. Ease off in amount and type of treat as she becomes reliable in her recall. Once recall is consistent, keep it sharp by using randomly to ensure it will work when needed. (Recall to short circuit unwanted behaviour, like eating poo, barking, wandering etc.) Good luck.

It is light weight, easy to blow; very very effective in terms of dog response when the whistle is blown with a command.

As for being a regular whistle - 5 Stars. For being a dog whistle, you can hear it. Feel free to correct me if I am wrong, but the point to a dog whistle is only dogs can hear it. Again, as a whistle - it is well made and very loud, which is why I have to return it. I don't want to disturb my neighbors. They would definitely hear me blowing this whistle during training sessions.

The acme 211.5 is an excellent choice of whistle.I have used the same brand and style for over a decade and have not been disappointed. A single whistle lasts around 5-7 years with daily use.Being made from plastic makes it easy to clean and keep maintained. I’ve have put muddy / swamp dropped one in the dish washer to clean it up with no issues in performance.It has a nice lower tone / sound that doesn’t leave you with a migraine at the end of the day.Not only do I and my team members use this whistle, I recommend it for my clients as well.Individuals complaining that it is not silent and leaving 1 star reviews over this would do well to pay attention to what they are actually purchasing.

It's basically just a softer whistle to the human ear. Makes more noise that what I would have expected to hear so definitely not going to be using in our apartment building hallways. I'll stick to the shaker training toys for that. The dogs seem to respond better to that anyways. If your dog responds to whistles and you don't mind hearing it then this is perfect for you.

Works as advertised, however I wish I had purchased a bright color. I had the whistle in my "treats bag" and started running with my dog, The whistle fell out at some point and it took me a while to trace my steps and find it. Had it been a bright orange or yellow, it would have been much easier to find. The whistle is loud and with proper training, dog responds to call. I suggest putting the whistle on a lanyard.

Train your dog correctly with this whistle and you will never have to worry about your dog coming when you call. This whistle is small and produces a perfect-pitch tone that is not affected by your mood, attitude or frustrations with your dog. This whistle will help you command your dog and get them to come on first call. Yes, it really works like that!.... here is how I trained my dog with this 211.5 whistle: Start with a HUGE portion of lunch meat in your hand. Let your dog play in your fenced yard and let him or her get distracted, so they are not looking at you. Now, figure out a pattern tone to use and use it every time for the "Come" command.... (I use two short blasts) EVERY time you whistle, and they come, they get a HUGE helping of this very high value lunch meat treat. (NOT KIBBLE, NOT DOG TREATS) this must be a very high value treat... chicken, beef, port, whatever they CRAVE the most. Always reward them with this treat EVERY time they come. (so it takes a bit of preparation for training). Within two days (5 - 6 initial calls and rewards) I was able to recall my dog from 100 yards away, even with other dogs and distractions present. I then, slowly, started reducing the size and value of the treats. Now she comes with the whistle and only expects a bit of lovin'.... but every once in a while I surprise the heck out of her with a HUGE pile of lunchmeat in my hand. I keep her wondering if "THIS" time is the time with another high value reward like chicken or beet. This is not the only training method to use for this, but it worked for me. I keep two of these whistles with me at all times... one on a lanyard, one on my key chain. It's all you will need to command your dog. I highly recommend it.

It makes the perfect sound. I wasn't sure about buying it because there wasn't a "sample" sound whistle on site, but I read the other review, which told me what I needed about wanting a loud, precise whistle.The sound is loud and pitch perfect. My dog training starts today.Will write back to let you know if it is effective for retrieving my dog when he takes off on one of his adventures!Well, I'm back, and within 3 days of using this whistle when my dog runs away, I have had great, successful results accompanied by small, healthy treats everytime he returns to the sound of the whistle...and he now always returns!The first two times that I used the whistle, my dog returned, but was confused and remained at a distance(thinking he was in trouble), I then called to him and reinforeced "good-boy", while holding a treat.By the 4th time, he came back, and I gave him a happy, verbal positive greeting and did not need the treats.I LOVE IT and MY Dog seems to feel the same!
