The HGM-1 Pen Microphone has the same ultra sensitive pickup range of the HGM-1 hi-gain microphone, but it's in a discreet pen form.
As the most powerful microphone on the market, the HGM-1 Pen Mic will get you at least triple the audio pickup of the lesser microphones. Most computers and tape recorders come with an inexpensive microphone that will only pickup voices from 2 to 3 feet. There's a number of reasons for this, such as lack of power to the jack where you plug the microphone in. If your microphone doesn't use a battery, then its made for dictating (speaking within 2-3 feet of it). The HGM-1 utilizes a hi-power battery which lasts 600 hours and allows the microphone to actually track voices up to 45 feet away while filtering out background noise such as air conditioning & paper shuffling.
