New advanced K18 spy bug detector used for all kinds of bugging such as: listening device, car tracker, wireless camera, mobile phone spy software. A great instrument for catching con-artists and scams that use the latest technologies. This detector meets the needs of military and police surveillance. It adopts a digital receiving module with a wider detection frequency domain and avoids the disturbance from other signals. Improved sensitivity control giving the advantage that no matter how strong the signal it can be adjusted to locate the source. It is the one of the most advanced portable detectors now available.This brand new 2019 RF sweeper can detect and locate CDMA signals. CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). Other wireless detectors can not detect CDMA signals. Originally invented by the U.S. military for anti-spy detection and contains radio frequency hopping technology called Code Division Multiple Access. This type of signal is normally hard to detect but can now be easily and accurately detected.Although this detector can find CDMA signals it won't detect devices that are not in use. This includes devices that are switched off - non active - sleep mode devices. The device must be active and transmitting a signal for K18 to detect. If the suspected device is off or not in use then there is nothing to detect. It will only detect when activated and in use sending and receiving signals that are detectable.This will not detect anything when scanning over a switched off tracker. It will detect magnetism used by 98% of vehicles trackers wether switched on/off. It will alarm you when placed anywhere near a magnetic surface mounted devices. Especially useful when sweeping the underneath of a vehicle.FeaturesProfessional radio frequency detection deviceHigh sensitivity with adjustable thresholdEasy to useSound and light alarm indicatorAccurate and reliableDetects mobile, 2G, 3G, 4G & WiFi devicesDetects High-speed upload GPS locator packet locatorDetects 1.2G/2.4G & 5.8G wireless camerasDetects hidden wireless WiFi camera and wireless eavesdroppingDetects magnetic surface / magnetismTechnical DataFrequency Range：1MHz-8000MHz (8GHz)detecting the dynamic range：＞73Dbdetection sensitivity：≤0.03mw（main frequency）Detecting range：2.4GHz wireless camera: 15㎡ (standard 10mW camera)1.2GHz wireless camera: 10 ㎡ (standard 10mWcamera)Mobile: 2G, 3G, 4G: 10 ㎡
