The Audio Pencil Probe allows one to gather intelligence during siege and hostage situations. The instrument contains a high quality amplifier and an extremely sensitive miniature microphone which combine to produce exceptional audio quality. 

The kit includes three small diameter listening probes which snap-lock to a pencil grip handle. The probes come in the following lengths: 

1mm x 50mm 
2mm x 100mm 
4.9mm x 250mm

The system contains an integrated Electret 2.6mm microphone with excellent response and sensitivity and  a 2.5 metre lead that in turn connects to a pocket size battery operated (PP9) amplifier box with ON/OFF switch and video out socket for recording.
