Trill and whistle combinedin one dog whistle model 642 - from the leading dog whistle manufacturer ACME from England.
Uniquely designed trill whistle that combines the famous Acme Thunderer Trill Mod. 560 with a single tone / whistle model 211.5.

manufacturer ACME understands like no other, even over decades to produce dog whistles in absolutely identical pitch.
Therefore, quite clearly our recommendation from our own experience in hunting dog training: Decide for your first dog either the combination model 641 or 642 and immediately buy a stock of the identical dog whistle in stock for your cars, various jackets and your family members.
And, stick with the dog whistle model once chosen over the years! Your dog will always know that HE is meant.
