Great for P.I. or police work. Place this anywhere you'd like to monitor, and the sensitive little onboard mic will do the listening for you. You can tune it anywhere between 90 to 94mHz in the FM band, then you can find it with a regular FM radio (within 200 to 300 metres, depending on walls/interference), to listen or even record!
It is your duty to obey the laws of your country. Some countries do not allow any unlicensed FM transmitions, even short range ones such as these.
Please use this kit with your best ethical and legal discretion, as it's designed for educational purposes (no one likes an eavesdropper).
