Recommended by the DofE and featured on the DofE Expedition Kit List, this whistle is one of the most powerful for all-weather conditions. The Lifesystems Hurricane whistle performs brilliantly as the tri-tone sound can be heard in all directions at 122 decibels. It can be heard further away than other whistles, making it an ideal choice for first time youth campers, festival goers, DofE participants and Scouts expeditioners. 122dB loudnessTri-tone soundFloats on waterNeck lanyard and attachment clip
