The Motorola PMMN4029 Submersible Speaker Mic is designed for use with the Motorola R2 two way radio. This remote speaker microphone allows you to communicate clearly in difficult weather thanks to its Windporting technology. Windporting eliminates the whining and howling sounds of wind blowing across your speaker microphone while preventing water from clogging the microphone, resulting in clearer transmissions. The PMMN4029 is approved to IP57, which means it can withstand immersion for at least 30 minutes and dust won't affect the operation. The PMMN4029 is rugged and built for the job, withstanding harsh conditions.
