Product Description

F-999B is a high sensitive partition monitor, which is perfectly constituted by metal receiver, metal handset with superior detecting ability and high-quality headphones, making it more sensitive and sound-qualified. It owns built-in Lithium battery and unique FM transmitter function, easy to be manipulated and carried. If James Bond 007 has this military grade partition monitor, he’ll have eavesdropped on many conversations by disguise himself as a lodger next door. However, the cool weapon can be available to you at this time, how could you miss it? Actually, it isn’t complex to use this partition monitor. You simply need to put the earplug into headphone hole, the sonde into the MIC hole, and clockwise rotate the Switch On/Off button of the volume. When the indicator light that the machine begin to work, boot the machines and adjust the volume, smoothly stick the sonde to wall that need to be monitored without any discretional move, adjust the gear-choice buttons A/B/C which emit different frequencies to explore the audio until you can clearly hear the sound from the room which can be amplified 20,000 times of sound. Therefore, it’s really vivid support of an old saying, "two may keep counsel - if one of them’s dead", which in fact, the only one survivor couldn’t be able to keep the secret suppose he should never woefully meet this partition monitor. One should always believe the truth that walls have ears. As a FM hole included, this partition monitor also supports record the audios by using recording equipments to go through the mouth of the recording and connect the audio cable. Again with special FM wireless emission function, the specialized FM receiver of this monitor can receive the information afar and monitor that frequency 100 MHz once you adjust the gear to D to start partition bougie monitoring. As for the bougie, we’ve provided because of the sensitivity of the machine depends on different thickness, materials of the wall and other interference factors. As a result, a bougie is provided the same as the sonde to enhance its penetrability especially for thicker wall. If you have enough potential to be a would-be spy, will you want to know whether this partition will eavesdrop via ceiling or floor, which indeed, need further exploring and experience with this unique wall detection partition monitor by yourself.
