Non Linear Junction Detector Model COBRA NLJD 09 is designed for search and detect various types of covert listening devices, RCEID. COBRA is capable of detecting almost any electronic appliance in any operational mode: active, stand-by, switch off/ The design of out devices consists in detection of radio microphones, microphone amplifiers, Dictaphones in premises (walls, floors, ceilings, furniture, etc.)

Excellent detection range, ERP up to 4W coupled with > -115dBm sensitivity. Dual Harmonic continuous wave (CW) OR Pulse transmission removes risk of missing a target due to sweeping too quickly, Light weight, balanced ergonomic design for ease of use. All cables are well secured giving added advantage in the field of operation.
