Find phone calls, data, SMS text messages, registration signals, 2.4GHz and 5.1GHz bands, scanning over 750,000 per second
Switchable dual antenna system – omni-directional to find activity, and directional to track down individual phones
Displays the service provider, signal strength and time and date of detection in an instant, downloadable log

Survey

Get an understanding of how much cellular activity is occurring in your facility. The Hunter will log detections as well as report the frequency, signal strength and even service provider when using regional profiles.

Hunt

Once a target has been identified, instantly switch from the omnidirectional antenna to the directional antenna with the push of a button and start to Hunt! The speed and power of the Hunter will allow you to identify the signal source even at long range.

Protect

Keep your facility free of illicit devices such as phones, tablets, laptops, smart watches, PEDs and espionage devices such as bugs or spy cameras by regularly checking for Cellular, WiFi and Bluetooth signals.

Feature rich, easy to use wireless signal detector

The Hunter™ is both feature rich and easy to use, delivering the power of spectrum analyser technology into a simple to operate wireless signal detector.

Rugged enclosure

Made from carbon-fibre, the casing is durable, lightweight and includes hand straps for secure use. Can also be mounted on a tripod.

FAQs about Hunter

What is the difference between standard and survey mode?

The key difference between Survey Screen Mode and Standard Screen Mode is that there are cellular band indicator bars rather than network operator indicator bars. The survey screen display is similar to a spectrum analyser interface and is useful if you wish to survey the range of frequencies being detected at any one time, rather than only seeing the strongest signal. This may help to give an idea of the amount of activity that is taking place.

What does the detection log capture?

The detection log shows the network operator, a relative signal strength shown in bars, the frequency, date and time of log entry, and signal strength in dBm. The log updates once per minute, showing the strongest signal detected independently for each network operator in each minute timeslot.

Can I download the log files?

Comms-Tek provide a dual USBA/C drive onto which you can download log files to transfer to your PC. Files are in CSV format.

What can I do if the receiver is detecting frequencies beyond the intended field of detection?

The Hunter is built with a very sensitive RF receiver. In some situations, this sensitivity needs to be reigned in so that it is not alerting the user to frequencies beyond the intended field of detection. We have included an attenuation setting so that the Hunter can be made less sensitive overall while still allowing the user to apply all three sensitivity settings on the main user interface.

How do you switch antenna?

The Hunter comes with omnidirectional, directional and probe antennas which are instantly switchable via the user interface. The omnidirectional antenna gives the user a 360-degree field of detection, in order to survey in all directions. The directional antenna has a 60-degree field of detection which is mostly facing in front of the user, in the direction of the pointed end of the antenna. The probe antenna can be used in place of the omnidirectional antenna in order to survey for device usage in a closed room or cell by placing the end of it underneath the door. Using this method, the operator can determine from which room a device is being used.

How do you set the correct regional frequency profile?

Your frequency file will be provided by Comms-Tek and can be set by going into the info and settings screen and pressing the drop-down box below “select frequency file”. This will determine which frequencies are allocated to the network providers. It is important that the correct file is selected based on your location or scope of desired frequency detection. If the incorrect file is selected, the Hunter may show incorrect network operator data.

What do I do if I experience interference when surveying?

Occasionally you may find that you are detecting interference signals which are emitted from sources other than a phone. These can come from electrical equipment such as old wiring, computer monitors, microwave ovens, communication equipment or cell towers/cellular base stations. Typically, interference signals are relatively stable signals, unlike cellular signals which are generally observed as somewhat intermittent.
The Hunter employs a frequency filter so that you can remove these signals from the detection scan, allowing you to continue your search without being confused by these interference signals.
