An incredibly loud whistle. Compact with no moving parts. This British made whistle is used in Special Forces survival kits, and is used by mariners and sports people. Many don't see the point of including a whistle in their kit but if your faced with a real survival situation you will be glad that you decided to buy it as the sound travels much further than a human voice which is the difference between being found and staying lost.
