Entel CMP450/DXS.
A submersible, very rugged, heavy-duty lapel speaker microphone for the DX series portable radio. Attached with a rotating clip, it allows the radio user to wear the radio on their belt and have the ability to both make and receive calls without removing their radio. This keeps the radio secure and ensures that calls are not missed, especially in noisy environments.
