Communicate clearly in difficult weather with these Windporting Remote Speaker Microphones. In howling wind, driving rain and severe weather, Windporting helps you communicate effectively and hear clearly. Windporting technology eliminates the whining and howling sounds of wind blowing across your remote speaker microphone. It also prevents water from clogging the microphone which results in clearer transmissions.
These microphones are available in two models. The submersible version is IP57 rated at 1 meter for 30 minutes. The water-resistant model features a 3.5 mm audio jack that allows you to connect a receive-only earpiece for private communication.
