Clear communication is one of, if not the most important aspect of successful days in the backcountry and the BC Link Radio is a very effective tool in aiding group conversation. Your pack houses the base unit while the microphone clips onto your shoulder strap. The base unit utilizes a rechargeable lithium ion battery, is waterproof and compatible with all standard FRS/GMRS radios. The mic unit is glove-friendly and includes a push-to-talk button, power switch, volume control and channel selector. Communicating with your entire team, even from the next ridge over, has never been easier.
