The BC Link 2. 0 is the second generation of Backcountry Access's two-way radio designed specifically for backcountry touring, and it comes with twice the wattage for a better performance at the recommended distance of 6 miles and the maximum distance of 40 miles (both with line of sight). The remote-friendly Smart Mic has glove-friendly controls for on-and-off, volume, battery indicator, channel selection, and push-to-talk so you don't have to find the base unit packed inside your backpack to change settings. BCA designed the Smart Mic to shed snow so it never ices up or packs down with snow. The BC Link 2. 0 is compatible with BCA's Float Avalanche Airbag and Stash Backpacks.
