The device is designed for experts in the field of industrial, political and business counter-intelligence activities, it makes their job quicker and more efficient. Besides, it suits those who are not tech-savvy because its operation is very comprehensive, one can search \'bugs\' with one touch! It is very handy and convenient with a weight of only **0 grams (3.9 oz).

Key specs:

• Built-in frequency meter automatically detects and displays an operating frequency of the detected bug. It allows BugHunter Professional BH**3 Expert to quickly identify the type of the bug and its location in the room. The system recognizes all the most common frequencies:

- GPRS, EDGE, 3G4G (cellular communication and data transmitting);

- DECT (cell phones and radio modules of DECT standard);

- DECT BASE (base stations of DECT standard);

- BLUETOOTH (radio modules of BLUETOOTH standard);

- WLAN (wireless network such as Wi-Fi, Zigbee, LoRA etc.);

• Updated system of noise filtering. Due to built-in frequency meter the device automatically determines which filters should be enabled for more effective \'bug\' detecting in a certain location, and display the corresponding information on the screen.

Main advantages:

1. Fast search bugs at a touch. BugHunter Professional BH**3 Expert  one of the most technically advanced and fast detectors. It can find a \'bug\' in just a few seconds!

2. Detection of digital and analog bugs simultaneously without settings and switching to different operating modes. The detector has advanced quick-operating microprocessor to detect even modern bugs (for example those transmitting data by short pulses and invisible for most other anti-spy bug detectors). Its also important that the device can see digital and analog \'bugs\' at the same time.

3. Unique built-in GSM, 3G, 4G, CDMA, Wi-Fi, GPS filter. If the environment has some sort of extraneous background frequencies that interfere to search just filter them out. 

4. Visual multicolor OLED-display which shows all the necessary information: type or frequency of the received signal (analog and digital at the same time). It allows being in complete control of the situation at any time.

5. Coverage of the entire frequency range used by the most wireless "bugs": from *0 to ***0 MHz.

6. Registration of high dynamic range (*0 dB). For example BugHunter BH**2 which holds a leading position among similar devices for wide dynamic range and is considered one of the most efficient and sensitive has only *8 dB. The higher the dynamic range is, the better is the detection of devices with very high and very low power radio transmissions. This is very important in difficult conditions when there are both powerful signal sources (cellular phones) and weak signal sources (almost all types of bugs). Detector with high dynamic range will not read off scale and will find hidden bugs against a backdrop of cellular signal.

Detects almost any spy device:

• wireless bugs

• cell phones and radios in operation

• wireless microphones

• wireless videocams

• cell phone jammers

• GPS transmitters

Device advantages compared to gadgets of similar purpose are:

• Exact match of stated parameters

• Equally high sensitivity throughout claimed frequency range.  Extended dynamic range

• Both analog and digital wireless "bug" detection (short pulses)!

• Automatic adjustment of background radiation levels

• Extended operating temperature range

• Headphones connection for implicit warnings of wireless "Bugs"

• Advanced power saving features (increased operational duration)

• Low battery power indicator. Automatic cutoff function to save energy

​Main modes of operation:

Search. It is enabled by default. OLED-display shows graphics of signal levels: maximum values and averaged values for 3 seconds and *5 seconds (in the form of three separate blocks of *5 seconds). Digital "bugs" can be found in the chart of maximum values, and analog "bugs" appear in the chart of averaged values.

Security. Turn on "Security" mode if you need to have constant control of the situation, during negotiations for example. The device keeps scanning the space in this mode. It will alarm you if any wireless bug or hidden transmitting cell phone appears.

Feedback. "Feedback" mode is used for searching hidden microphones (wireless "bugs") operating in analog mode. This allows the wireless "bug" to capture the sound emitted by the device, and broadcast it. The radio signal is detected and increased by the device, so the circle closes up and the device produces a characteristic "whistle." Feedback mode is the most accurate method of "bug" detection, it reduces search time.

Acoustic indication. In this mode graphic indication is complemented by acoustic indication. A speaker emits sound signals and their frequency inform about power of detected devices (more often the sound, the higher power).

Mute. This is excellent operating mode for those who do not want to draw attention. All sound signals are turned off, including the sound of setting up and pressing the keys. However, in this mode you can also conduct a search, without looking at the screen by setting on vibration signal.
