SW-Parabolic Mic

Magnify faint or distant sounds with the powerful BM &
Booster pinpointed sound amplifier/listening device. The BM
increases sound by up to 40 decibles using an omnidirectional
microphone, a solid-state amplifier and hi-fidelity
earphones for concert hall quality sound reproduction.When
combined with the optional 12-inch parabolic Booster, the BM
becomes highly directional, allowing you to easily locate the
source of sounds and suppress background noises. Hear
mere whispers at incredible distances. Detect animal
movements for nature observation or photography or direct
the microphone toward a distant conversation for surveillance
or personal safety. Record bird calls and other sounds with
the recorder output jack. The BM Booster is the only
pinpointed amplifier of its size available to the consumer
market. Uses include surveillance, law enforcement, personal
security, search & rescue, hunting, hard-of-hearing,
wildlife observation, outdoor adventures, camping,
birdwatching, and much more.
