The Garrett Letter scanner stops terrorism by mail. This attractive desk-top unit is specifically designed to find metallic objects that indicate the possibility of an explosive device in a letter or small package.
Precise engineering permits the powerful unit to detect the presence of any metal .
Sensitivity controls enable the operator to make a simple adjustment that lets the Letterscanner sound an alarm on larger metallic objects such as batteries or the foil contact surfaces used in explosive devices. The presence of metal causes a light to be illuminated and an audible alarm to sound. For the office environment a cut-off switch on the alarm permits silent operation with the light alone indicating metal. Resembling a lectern, the Letterscanner fits into any office decor. It operates on standard alternating current with a common wall plug.
