The PRO4000D has been in our range for a while now and have proved itself for both sensitivity and dependability and this is why it top of our range of reasonably priced bug detectors

Custom designed to detect and locate covert bugging devices the fuss free design and functionality make this unit simplicity to use. This unit is designed to scan a true frequency range of 1 to 4800 MHz (4.8 GHz) which encompasses the majority of bugging devices on the market

The sensitivity of this unit ensures that there should be no concern about not picking up a transmitter in the scanned range and its robust design and solid carry case means that it can be relied upon to perform again and again. The PRO4000D will detect and locate all types of radio transmitting bugging devices. These include battery operated transmitters or bugs, mains powered bugs, telephone bugs, video transmitters, mobile telephones and walkie talkies etc.

The green 10 LED bar graph display indicates the signal strength, along with an audible beep tone that increases the closer you get to a detected signal.Once you have located a suspect signal by simply attaching the supplied headphones you can use the 'Demodulation' facility to identify the type of device that is transmitting. The type of sound heard through the earphones can assist in identifying what type of radio transmission is being detected.

A low battery indicator is provided to ensure that you are never searching for bugs without maximum performance and the PRO4000D comes supplied in a protective plastic case with headphones, ready for immediate use.

Will this device find all radio frequency bugs?

The PRO4000 unit has a good frequency range, up to 4.8GHz and is designed to pick up most commonly available bugs that operate in this frequency range. It is recommended for checking the home or small office environment where the threat is relatively low.

Can the PRO4000 unit detect voice recorders?

No, voice recorders to not transmit a frequency and therefore cannot be detected by RF detection equipment. A Non-Linear Junction Detector is the only type of device that can detect this type of bugging device. This is why physical search is paramount.

Can the PRO4000 detect wireless cameras?

This product is able to detect wireless cameras that transmit on the 1.2GHz and 2.4GHz ranges, but does not cover the rare 5.8GHz wireless cameras. it is not sensitive enough to detect RF from 3G camera units. If 3G cameras are a viable threat then a unit that focuses on 3G signals is required.

Can I hear through the device when an audio bug is detected?

The PRO4000 does have audio demodulation, so this is possible if an analogue bug is detected.

Is the PRO4000 as sensitive as more expensive bug detectors that cover the same frequency bands?

The PRO4000 has decent sensitivity and can be considered for counter surveillance at home of in a small office environment. However, more expensive detectors are generally a little more sensitive.

Will the PRO4000 easily detect tracking devices?

Although it may be possible to identify tracker transmissions, this device is not recommended for this. One of our other devices with burst bug detection or dedicated GSM/3G ranges is ideal for tracking devices that transmit data bursts.

You will need to consider the following to use this equipment:

  • If using a bug detector for the first time it is advisable to test the unit in various 'friendly environments' to become conversant with the functionality
  • It is advised that a user should have a reasonable knowledge of frequency bands used by common bugging devices
  • Although the unit is supplied with a 9V PP3 battery, this will require replacing after some time. This type of battery is  readily available for many high street stores and online retailers
  • Pocket bug detector designed for situations with low to medium threat from bugging
  • Simple design - Easy to operate
  • Excellent sensitivity and durability giving outsnading reliability
  • 1 to 4.8 GHz Wide Frequency Response
  • High Sensitivity to locate the weakest signals
  • Audible Signal Strength 'Beep'
  • Audio Demodulation (for ease of detecting transmission type)
  • Flexible 'whip' antenna providing excellent frequency pick up
  • Low Battery Indicator
  • Supplied in a robust plastic case, with headphones and PP3 9V battery
