In some situations and locations, the use of a mobile phone is forbidden. You may
be discussing sensitive information in a closed meeting or holding important
exams. How can you be sure that a concealed phone is not being used to pass
information outside? Maybe you’re just curious and would like to know if someone
nearby is using a phone. This neat unit will not only detect the presence
of mobile phone activity (voice or text), it can home in on the culprit!
