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 omni- directional 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. FEATURES
