Remove that notion that whistles are only useful to boy scouts and traffic officers - a whistle could actually save your life when you are in a pinch! Such a being trapped in a rubble during an earthquake where no one could hear you scream. And to make this whistle more useful, it also has a compass and a Celsius thermometer which would help you save up precious space, if not act as a backup in the event that you lose your compass. Made of toxin-free, durable plastic material and uses a nylon cord.
Temperature range: -20-50 degrees Celsius
Whistle Size: 50 x 33mm/1.96 x 1.29 inch
