How loud can you whistle?
Not all whistles are the same. Some are used by policemen, some by referees while others are simply too awesome like the NWS10 Survival Whistle. Small in size but massive in performance. It is made of TC4 titanium alloy so it is light, corrosion resistant and very durable. This thing works on any weather condition and can produce up to 120 decibels, that's louder than a chainsaw and just 5 decibels short from being painful to the ears. If you want to be found, be a public nuisance or save a buddy from zombies this is the right whistle to blow.
