Standard Horizon CMP460 Noise-Cancelling Speaker Mic

The Standard Horizon CMP460 is a submersible noise-cancelling speaker microphone rated IP57, intrinsically safe, with push to talk.

IP57 means submersion to three feet for thirty minutes rather than splash resistance, which is the rating that matters for something clipped to a jacket on an open deck. Noise cancelling works on the transmit side, filtering wind and engine noise out of your voice so the station receiving actually understands the message.

Intrinsically safe certification means the microphone cannot produce a spark capable of igniting a flammable atmosphere, which is required around fuel handling. A speaker mic keeps the radio itself clipped inside a jacket while the microphone sits at the shoulder, so the radio stays dry and the audio stays close to the ear.
