Mil-Tec Bobby Whistle

Mil-Tec Bobby is a classic signal whistle made of nickel-plated brass. Its design is based on the traditional Bobby Whistle model used by British police since the early 20th century. The sound is produced by dividing the air stream into two paths, creating a cyclical pressure change in the chamber that generates a distinctive, highly audible signal. It features a convenient ring for attaching to a lanyard or keys, a resonance chamber for a sharp sound, and durable nickel-plated brass construction.
