Acme dog whistles are the definitive Gun Dog Whistle.

Developed over four years in collaboration with World Champion trainers to create an unrivalled whistle. Patented sound chambers offer a more efficient use of air. That means brighter sound giving you better command and a more responsive dog, close-to and over distance. These all-new designs are effortless to blow and, because of that, give you the greatest flexibility to vary your breath, your whistling style, and your choice of commands. The all over comfort grip offers softness in the mouth and perfect handling in all conditions. Over the fields and hills, on the beach, in your local park or at home this new range will ensure you lead your pack.

Each whistle has the appropriate pitch number embossed on the underside, the pitch being identical for each whistle with the same pitch number.

The 210 1/2 produces a high pitch note of 5900 Hz and as such is the highest pitch in the standard ACME range.

Whilst suitable for all dogs this whistle is especially suitable for spaniels. It can also be effective for older and some hard of hearing dogs.
