Lifesystems orange survival whistle

Here at GTC we always recommend travellers and hikers should carry a whistle for emergencies, and this is the world's loudest! At 122 dB it is piercing enough to attract attention, and its tough plastic body can be washed to keep it hygienically clean; also it is more comfortable to use in cold/icy conditions than a metal whistle as it less likely to freeze to your lips! The internationally recognised distress signal is 6 blasts of the whistle with a 1 minute break and then repeated. The reply is 3 blasts with the same pause.
