TM2 THROAT MIC

TM2 THROAT MICROPHONE ADJUSTABLE, ACOUSTIC TUBE WITH INLINE PTT AND EXTRA TIP

Absorbing vibrations directly from the throat offer a number of advantages over conventional microphones. Boom mics cannot function in high-noise and high-wind environments because they are sensitive to all sounds carried by air. Throat mics, however, pick up only vibrations from the throat and are insensitive to background noise and wind turbulence. They can be worn with helmets, masks, HAZMAT suits, and full-face breathing apparatuses. Because they do not interfere with the use of other equipment and are highly adaptable to a variety of extreme acoustic environments, throat mics are ideal for a wide variety of tactical and recreational applications.
