ACME - Tornado Finger Whistle 477 / T2000 Airfast High Output Adjustable Metal Grip with Cushion Pads Self Defence, Sports and Outdoors

THREE SEPARATE SOUND CHAMBERS, SIGNIFICANTLY LOUDER AND MORE DISTINCTIVE THAN A SINGLE WHISTLE: The T2000 contains three distinct sound chambers, each tuned to a different pitch, firing simultaneously when blown. The combined output is not simply louder, it is acoustically more complex, more penetrating, and more audible at distance than any single-chamber whistle can achieve. MOUNTAIN RESCUE RATED, BUILT FOR GENUINE EMERGENCY SIGNALLING: The T2000 Tri-Tone is designed and rated for emergency signalling in outdoor and wilderness environments. Its output meets the standards required for mountain rescue applications, a meaningful specification that defines a product tested against the acoustic demands of real emergency situations, not simply a loud sports whistle. FIFA OFFICIAL USE, THE STANDARD OF PROFESSIONAL SPORTS OFFICIATING: The T2000 is the whistle used in FIFA-governed football officiating. This is not a marketing claim, it reflects the T2000's acoustic output and reliability standards as validated for use at the highest level of professional sport. AUDIBLE OVER KILOMETRES IN OPEN TERRAIN: The tri-tone's overlapping, multi-pitch output propagates through air and reflects off terrain differently from a single-frequency signal. In open mountain environments, along coastal paths, and across exposed hillsides, the T2000's signal remains audible at distances a conventional whistle cannot reach. ESSENTIAL KIT FOR HIKING, CLIMBING, KAYAKING AND EXPEDITION USE: Any outdoor activity that takes you beyond immediate rescue range warrants a signal whistle rated for distance. The T2000 is compact enough to carry on any adventure, from a day walk on the South Downs to a multi-day high-altitude expedition.
