The standard for backup tape recorders, the ME-8 Half Pen Microphone picks up from 22 feet away with no need for a battery.
The ME-8 is designed to look exactly like half a pen so no one knows there's a microphone in the room. The pickup pattern is omnidirectional and will pickup 360 degrees around.
The discreet reporters choice. For use ONLY with Sony Tape Recorders.
