Sonic Assault is a unique high-pressure acoustic generating device which provides a substantial capability to disrupt and disperse. Speeches, demonstrations, crowd dynamics, etc. - this device has been used to "influence" more of these than you might think. Deployed near a podium, you might just have a case of an increasingly un-focused speaker with diminished sharpness and concentration. Or, loitering youths near a store entrance might be encouraged to move along without need of a confrontation.
This is the rarely-available government model which the popular commercial version Sonic Nausea was based on. It provides substantially higher sound-pressure levels, more directionality, increased projection, an on-off switch, and LED status indicator. This is the new latest generation 2012 version, and has nearly triple the output of the previous 2009 version. Limited quantities are currently also available for non-government sales. Powered by two 9-volt batteries (included). Size: 5 3/4" x 3" x 2 1/4". Deploy only with extreme discretion and in a lawful manner.
