Detects digital and analog bugs simultaneously without settings and switching to different operating modes. It reduces statics from cell phone towers. BugHunter BH-03 has very informative OLED-display which shows all the necessary data and allows being in complete control of the situation at any time. It is suited even for those who are not tech-savvy because its operation is very understandable, you can search bugs at a touch! Thanks to small size (weight only 110 grams) it’s quite handy. 
Detects almost any spy device!

• wireless bugs;
• working cell phones and radios;
• wireless microphones;
• wireless videocams;
• cell phone jammers;
• GPS transmitters. 

The main advantages of BugHunter BH-03:
1)    Fast search bugs at a touch. BugHunter BH-03 – one of the most tech and fast detectors. It can find a bug in just a few seconds!
2)    Detects digital and analog bugs simultaneously without settings and switching to different operating modes. The detector has advanced quick-operating microprocessor that’s why it finds even modern bugs (for example those which transmit information by short pulses and stay invisible for most anti-spy bug detectors).  It’s also important that BugHunter BH-03 can “see” digital and analog bug at the same time.
3)    Switched 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. Unique! 
4)    Visual multicolor OLED-display which shows all the necessary information: type of the received signal (analog and digital at the same time), history of changes in the last 45 seconds in clear graphics, mode pictogram, filters condition etc. It’s allows being in complete control of the situation at any time.
5)    It covers the entire frequency range that is running the most wireless "bugs":  from 10 to 3500 MHz. 
6)    Record high dynamic range (70 dB). For example BugHunter BH-02 which holds a leading position among similar devices for wide dynamic range and is considered one of the most efficient and sensitive has only 48 dB. The higher dynamic range, the better finding devices with very high and very low power radio transmissions. This is very important in difficult conditions when there are as powerful signal sources (cellular phones) as 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.

Device advantages before the gadgets of similar purpose are:

•  Exact match of stated parameters.
•  Equally high sensitivity throughout claimed frequency range. Unique!
•  Extended dynamic range.
•  Both analog and digital wireless "bug" detection (short pulses)!
•  Automatic adjustment of background radiation levels.
•  Extended operating temperature range.
•  Possible headphones connection for implicit warnings of wireless "Bugs".
•  Advanced power saving features (increased duration of work).
•  Low battery indicator. Has a function of automatic cutoff to save energy.
•  Self-diagnosis.

The 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 45 seconds (in the form of three separate blocks of 15 seconds). Digital "bugs" can be found on the schedule of maximum values, and analog - on schedule averaged.
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.

Sound modes: 
Feedback. "Feedback" mode is used searching for 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 the 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.
