I can hear this whistle from the other side of the field — and believe me, Dad has tested that! He uses the 211.5 and I know exactly what each pip means. One pip = sit. Three pips = come back (fast!). It's our secret language and I love it. Two paws up — the real deal! 🐾

- Available frequencies: 210.5 and 211.5
- Material: Nickel-plated brass

How To Use
- Choose your frequency — 210.5 for a higher pitch, 211.5 for a lower pitch. Most handlers stick with one frequency for life so your dog learns a single sound.
- Place the whistle between your lips and blow with a short, sharp breath for a single pip — use this for the sit/stop command.
- Use a series of short rapid pips (tweet-tweet-tweet) for the recall — your dog will learn to associate this with coming back to you.
- Keep commands consistent — the same number of pips should always mean the same thing.
- Introduce the whistle alongside your voice commands initially, then phase the voice out as your dog becomes reliable on the whistle alone.
- Clean regularly by rinsing with warm water and drying thoroughly.
Care Guide
- Rinse with warm water after use, especially in saltwater or muddy conditions
- Dry thoroughly before storing to prevent tarnishing
- Store on the lanyard around your neck or in a dry pocket
- Polish occasionally with a soft cloth to maintain the finish
- Do not drop on hard surfaces — the precision bore can be affected by impact damage
Professional Insight
The ACME Alpha is the field trial standard for a reason. The nickel-plated brass construction gives it a consistent, repeatable frequency that plastic whistles simply cannot match — plastic warps with temperature and moisture, which means the pitch drifts. In a training context, that drift is invisible to the human ear but detectable to a dog. The Alpha eliminates that variable entirely. The 13-colour range is also a practical professional detail: on a driven day with multiple handlers, colour-coding your whistle means you're never fumbling for the right one. At £10.99, it is also one of the best-value professional training tools available anywhere.
Training Academy Tip 💡
Choose your frequency before you start training and stick with it — switching between 210.5 and 211.5 mid-programme will confuse your dog. The 210.5 carries slightly further in open terrain and is the more common choice for Labradors and Retrievers. The 211.5 is often preferred for Spaniels working in cover where a slightly lower pitch can cut through more effectively. Whichever you choose, buy a spare in the same frequency and keep it in your bag. A lost whistle mid-season is a training setback you don't need.
ProTrain Principle
One pip to stop. Two pips to sit. A rapid trill to recall. The whistle is a language — keep it consistent and your dog will never misunderstand you.

FAQs
What is the difference between 210.5 and 211.5?
The numbers refer to the frequency (pitch) of the whistle. The 210.5 produces a slightly higher pitch and is traditionally favoured for spaniels and close-working dogs. The 211.5 is slightly lower and is popular with retriever handlers and those working at distance. Choose based on your breed and what your dog is already trained to — consistency is key.
Which frequency should I choose?
Frequency choice is generally guided by breed — 210.5 for spaniels and HPR breeds, 211.5 for Labradors, Retrievers and distance work. If your dog is already trained on a specific frequency, always stick with that one. If you're starting from scratch, ask your trainer or breed club for their recommendation.
Can I use this whistle for a puppy?
Absolutely — introducing a whistle from puppyhood is ideal. Start with simple recall pips alongside treats and your puppy will quickly learn to associate the sound with coming back to you.
Is it loud enough to be heard at distance?
Yes — ACME whistles are designed to carry at significant distance in open country. The consistent frequency cuts through wind and background noise far more effectively than a voice command.
Does it come with a lanyard?
Yes, the ACME Alpha whistle includes a lanyard so you can wear it around your neck and have it ready at all times in the field.
How do I clean it?
Rinse with warm water after use and dry thoroughly. Avoid dropping it on hard surfaces as the precision bore can be affected by impact damage.
