Professional Digital RF Detector is one of a kind counter surveillance device. Unlike  typical sweeping type devices it can detect modern 'hidden' bugs which use such protocols as Bluetooth and Wi-Fi. Such bugs, especially Bluetooth types, are practically undetectable by common RF detectors due to their very low transmitted power and a special type of modulation.  This amazing device uses a separate channel  (2.44GHz)  frequency pre-selector to detect and locate Bluetooth and Wi-Fi with a much higher sensitivity. The unit then processes the demodulated signal in order to identify which protocol has been detected.In addition the unit can detect all types of 'conventional' bugging devices (FM-modulated transmitters, digital transmitters, GSM-bugs, etc.)

Features & Benefits:

• Main antenna  40MHz – 4Ghz
• Auxiliary antenna 2.44 Ghz
• Increased sensitivity to Bluetooth/Wi-Fi signals allows the operator to detect wireless sources at distance of 50 cm- 2 m
• Detects GSM, Bluetooth, Wi-Fi and RF
• 16-segment bar graph indicator providing a wide dynamic range
• 4 work modes: silent, sound, vibration and mixed
• Correlation function discovers FM-transmitters by the presence of sound is different than other detectors this unit  can produce a loop-back effect  A microphone transmitter will pick up the sound and transmit the beep. The demodulation display will pick up the transmission and flash simultaneously. Also, when the unit detects other transmission different sounds will come from the unit depending the type of transmission it detects
• 2 levels of sensitivity (attenuator)
• Durable metallic body
• Microprocessor controlled
• Includes the extra antenna allowing the device to avoid interference from external sources in cities or near broadcasting towers etc.
