The Field Trailer from Dallesasse Whistles takes the British Acme 635 Pealess Whistle and adds a 5 in. long and 2 in. wide plastic megaphone, giving it a 400 yd. range! This whistle is loud, high-pitched, and shrill, made especially for hunting on windy days and long distances.

As its name states, perfect for handling long-ranging pointers in American Kennel Club (AKC), American Field (AF), Field Dog Stud Book (FDSB), and Amateur Field Trial Clubs of America (AFTCA), and National Bird Hunters Association (NBHA) field trial events. This whistle can also be used in coon hound, foxhound, or beagle field trials with the AKC or the United Kennel Club (UKC).
