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. Please note: not to be used outside. This device requires an open space with walls to work properly.
