Counter-surveillance receiver
Any surveillance agent will not be alerted by ultrasonic tone. Sonic marking technique, a powerful method of detecting room transmitters - ideal when monitoring sensitive locations. It is possible to find surveillance devices and accurately display the distance from the receiver.
Detection Capability Comprehensive
The use of 4 built-in receivers operate simultaneously the device can detect a variety of broadcasts and provides detailed analysis including signal differentiation, allowing detection of shoved transmitters operating in an environment in which radio frequency signals are much stronger. Built-in receivers are wide frequency modulation; narrow frequency modulation; amplitude modulation and transmission of the sub-carrier.
Automatic and manual modes of operation
Accessible via menu, user-friendly design and a number of software controlled manual modes of operation provides the user with a comprehensive and advanced set of tools. In automatic mode, a series of procedures is performed for detection and verification without further user intervention
Frequency Environment Memorising Radio
Storing a radio frequency map up to 7 buildings, the device will allow the operator to check if any additional equipment has been added to these environments.

Case
Sturdy carrying case
Can detect and analyse transmission devices without any
trace of the detection. A silent sweep with an ultrasonic signal ensures
discrete detection without alerting the surveillance systems which
could compromise your confidentiality. Any surveillance agent will not
be alerted by an ultrasonic tone. The sonic labelling technique,pioneered
by Eskan in the Ranger, is a powerful method of detecting room
transmitters - ideal when monitoring sensitive sites. It can locate and
surveillance device and accurately display the distance from the receiver.
Comprehensive detection capability
Using 4 built-in receivers operating simultaneously Ranger 3 can detect
the whole range of transmission and provides a detailed analysis including
differ-entiation of signals, enabling detection of snuggled transmitters
operating in an environment in which there are much stronger radio
frequency signals. The built-in receivers are wide frequency modulation;
narrow frequency modulation; amplitude modulation and sub-carrier
transmission.
Automatic and manual operation modes
The approachable menu driven, user friendly design and the range of
soft-ware controlled manual modes of operation give the user a
comprehensive and advanced toolkit. In the automatic mode a range of detection and verification procedures are performed without further
user intervention
Memorising Radio frequency environment
Storing a radio frequency map (signature) of up to 7 buildings using
Ranger 3 will allow the operator to check if any additional equipment
has been added to those environments
