Does Hunter Mobile Phone Detector identify callers or their phone numbers? 

No, but when regional profiles are used Hunter can identify the service provider of the detected signal.

Can Hunter detect more than one mobile phone at a time? 

Yes. Access survey mode to identify multiple phones using various sections of the cellular spectrum.

How far away can I detect mobile phones? 

175 feet (53 metres) indoors, up to 1000 feet (300 metres) outdoors.

Does Hunter Mobile Phone Detector detect phones that are powered off? 

No. A phone that is turned off cannot be detected.

Can Hunter detect text messaging as well as voice calls? 

Yes; the Hunter will detect and log all transmissions, even short burst signals like SMS texts.

Can Hunter detect smart phones browsing the internet or using data-based call services? 

Yes, the Hunter is designed to detect TDD data transmissions. Therefore, it can differentiate data uplinks from downlinks, a first in handheld phone detector technology.

Can Hunter only detect mobile phones or can it locate them as well? If so, how? 

Using the directional antenna, the strongest signal bar on the Hunter will peak when facing in the direction of the signal source. It also comes with a probe antenna that can slide underneath a door of the room that you suspect is the point of the illicit phone.

Can Hunter transmit RF signals? 

No, Hunter only detects RF signals.

Can Hunter units be networked together? 

No, but ask us about the Watchman installable networked phone detector.
