Almost everyone, from small children to seniors, can benefit from our patent pending JetScream's™ piercing whistle. Ultimate Survival Technologies is proud to offer our JetScream™ Whistle. This whistle is one of the loudest in the world, any louder and it would cause physical pain, literally. You can hear JetScream's™ amazing 122Db ear-piercing shriek, above most natural or man-made noises. It is equivalent to the sound of a rock concert or a jet at take off. You can use JetScream™ in the city or woods for communication and personal protection. You don't need a big bulky whistle to make a loud blast and this sleek little device proves it!
