The Acme ALPHA dog whistles are a new and improved design, perfect for all types of dog training. 
 
Without the pea, and with an ultra high pitch, this whistle produces a solid, high frequency tone perfect for handling in all conditions.
 
Here at High Peak Gundog Supplies we currently stock the entire range of colours.
 
We recommend using the 210.5 whistle with Spaniel Breeds and for close work.
