Ideal for covert and plainclothes officers, TCI's Covert In Plain Sight (CIPS) Communications Kit connects to a tactical radio and enables two-way communication through the earbud microphone, just like a cell phone. A separate micro PTT (Push-to-Talk) hook-and-loop ring attaches to a fingertip or belt loop, enabling the operator to key the radio and use the microphone in the headset without any indication to outsiders that a tactical radio is in use.
