The Wire Web tripwire detection system was developed for police officers and soldiers who may have to navigate through a potential tripwire hazard. Spray the string across the intended pathway and the string will hang from the tripwires like icicles in midair, letting you know if the path is booby trapped. Wire Web is currently being used by SWAT team members as well as soldiers in Iraq and Afghanistan. There are several key factors that separate Wire Web from "party store" string.
