Is what you say being tapped? Why would some people know things that they are not supposed to know? Has someone hidden mini cameras around?Whether it is about your personal life or your business, you feel you are being watched by people who do not want any good to you. If you are worried, then it is time to know whether there is reason for concern. With this little device, you can easily locate wireless cameras or audio micros (aka bugs). Keep it with you at all times until you know all is fine. It is small enough to be carried around. Use it prior to a meeting or any such situation that requires intimacy or privacy. And if you detect something, either de-activate it or use the knowledge to your advantage by providing deceitful information.Detection Frequency- Scope of sensitivity range: 1 MHZ-8000 MHZ- Primary detection range: 25 MHz-6000 MHz- Detecting dynamic range: >70DbCoverage Area: Up to 25 metersIndicate mode: Nine level LED bar graph with increasing optic sound alertPower Source: 9V alkaline batteryBattery Life: 120 minutesDimensions:- Antenna off = 125mm x 65mm x 25mm - Antenna on = 280mm x 65mm x 25mmWorking temperature: -10 to 50 deg
