Collarset III lets officers receive and transmit portable radio signals without being observed by people in the surrounding area. Available from Television Equipment Associates, it provides hands-free radio communications. One cable runs under the officer's shirt to a flat microphone/earphone unit positioned over the breast bone. A fingertip press-to-talk button is located on the duty belt, hand or pocket to facilitate discrete radio transmission. A secret service-type coiled tube transmits the receive signal to a comfortable skeleton earmold, which does not obstruct peripheral hearing. For cover applications, the tube can be located up the back of the officer's neck.
