Just like the HGM-1 in extreme pickup range and quality, the HGM-2 has a built-in battery tester. This ensures you a worry free day of crystal clear audio. Never again switch out that battery just because you are unsure of its charge.
As the most powerful microphone on the market, the HGM-2 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 75 feet away while filtering out background noise such as air conditioning & paper shuffling.
What makes the HGM-2 court reporter microphone so special?

The software in this Court Reporter Microphone raises the human voice and lowers the back ground noise. This is extremely important when you are scoping to understand what is being said.
