The ACME Alpha 210.5 is a weatherproof professional dog training whistle for clear recall, with a standardized 5700 Hz frequency and patented sound chambers.

• Standardized 5700 Hz frequency — helps dogs recognize the same whistle call across different handlers.
• 110 dBA sound and an approximate 100-yard range — gives handlers a signal for close and distance training.
• Patented sound chambers — use air more efficiently to produce a brighter sound.
• BPA-free plastic made to food-grade standards — pairs with an ergonomic grip for handling in all conditions.
• Made and rigorously tested in the UK — produced by specialists with over 150 years of experience.
• Turquoise, pealess design — a ball-free, cork-free whistle that weighs 0.013 lb (6 g).

For recall and training, a whistle offers a consistent cue that can carry beyond speaking distance. The ACME Alpha 210.5 is designed for smaller dogs and is preferred by Spaniels, Cockapoos, Dachshunds, and other smaller breeds. Its standardized frequency is useful in households or routines where more than one person may give the same whistle call.

What makes the Alpha 210.5 suitable for distance recall?

Its patented sound chambers are designed to make efficient use of air and create a brighter whistle sound. The whistle delivers 110 dBA and has an approximate range of 100 yards, supporting calls both nearby and over distance. ACME developed the design over four years in collaboration with World Champion dog trainers.

• Made for close-range and distance commands.
• Designed to support a more responsive dog through a clear training signal.

Will my dog recognize the whistle if another person uses it?

The standardized 5700 Hz frequency gives the ACME Alpha 210.5 a consistent call for a dog to recognize. The same frequency can be used across different whistle colors, so color can help distinguish whistles used by a partner, family member, or dog walker without changing the sound cue.

• Suitable for shared training routines with multiple handlers.
• This version is turquoise.

What are the whistle’s size and grip like?

The ACME Alpha 210.5 measures 3 inches (7.8 cm) long, 0.5 inches (1.3 cm) wide, and 0.5 inches (1.3 cm) high. Its improved ergonomic grip is designed for comfortable handling and softness in the mouth.

• Made from BPA-free plastic to food-grade standards.
• Pealess construction, with no ball or cork.

For handlers training smaller dogs who want a consistent recall cue, the ACME Alpha 210.5 combines a standardized frequency, a weatherproof build, and a compact ergonomic form. Its UK-made, rigorously tested construction and pealess design suit everyday whistle training in varied conditions.
