This Remote Speaker Microphone with Windporting technology allows you to communicate clearly even in inclement weather. Windporting reduces the whining and howling sounds of wind blowing across your remote speaker microphone while also preventing water from clogging it, resulting in clearer transmissions. This RSM is suitable for use in hazardous environments, as it has intrinsic safety approvals to FM regulations. This RSM also has a 3.5 mm audio jack, so you can connect a receive-only earpiece for discreet communication.
