The BCB Emergency Whistle is a loud sounder worth having in your survival kit.
Application
The emergency whistle is a simple sound generator used for signaling and calling for help, which is why it is included in a marine life jacket and survival suit.
The BCB Howler Whistle has been approved by SOLAS (the International Convention for the Safety of Life at Sea), and is also included in the survival kit of British special units.
Construction
The whistle is made of plastic with high resistance to mechanical damage, adverse effects of sea water and weather conditions. There is a steel attachment ring in the back for attaching the whistle.
