When heading into the backcountry for fresh lines, we slip the Backcountry Access Tracker S Avalanche Beacon into our shell. Simple and streamlined, this transceiver doesn't feel hefty in our pocket and helps us act quickly in the event of an avalanche. The temperature-resistant LED display gives us real-time data, including multi-burial and close-proximity indicators, while the auto revert mode quickly switches back to transmit mode should another slip occur while we're searching.
