A whistle does you no good in your pocket. The Avery ASD Single Clip Whistle Lanyard keeps one whistle riding on your chest where you can get to it mid-drill, without the bulk of a full trainer's lanyard.
Retriever training and handling in the field, plus anyone else who needs a whistle handy: coaches, referees, and range or law enforcement use.
Ships fast or pick it up in store at Lake Charles Tackle.
