Random Search Selector - Hand Held Battery Powered Unit

Often used alongside metal detectors (see: http://www.insight-security.com/metaldec.htm)  and other search equipment, these robust Random Search Selectors - offer a simple, reliable and guaranteed “Unbiased” way to select persons (from a group) to be searched (when it is either impractical or undesirable to search everyone passing through a control point).
 
This battery powered version of the Random Search Selector operates in a similar way to its mains powered big brother, but is powered by 3 x AA batteries (which typically offer over 12 months operation from a fresh set).
 
Designed originally for use with vehicle / driver selection, for search or inspection activity, this versatile unit has also been adopted for a wide range of other applications. The internal dipswitch settings determine the search selection rate (from 0-100% in 5% increments), whilst the robust 50mm(diam.) push button is the trigger mechanism
