Just in time for Halloween comes the perfect device for repelling mischevious trick-or-treaters. That is if you happen to be the neighborhood's resident mean old man and don't mind causing the little monsters some intense headaches and nausea.

The Sonic Devestator from Future Horizons is aptly named. It blasts ultrasonic waves similar in sensation to the sound of fingernails on a blackboard ... magnified to the volume of a rock concert (130 decibels). Anyone within 20 feet of the business end of the Devestator will be strongly motivated to vacate the area. Some particularly sensitive individuals may feel it even 50 feet away.

It's even more effective on animals such as dogs because of their greater hearing range. Future Horizons assures us that the Devestator causes no permanent damage or ill effects, though a targeted individual might need an hour or so to recover. The ultrasonic waves are directed in a 45 degree cone from the "muzzle" which keeps the wielder unaffected, though you'll definitely know when it's on.

And speaking of rock concerts, Future Horizons also sells a "riot control" version of the Devestator that combines six of the transducers into a single unit. So those kids may also want to think twice about having any loud parties next door to that mean old man.

Sonic Devestator: $150.00
Sonic Devestator (riot control): $399.00
