Black Diamond BD Guide BT Beacon

An avalanche transceiver built for ski guides and advanced backcountry practitioners who search for multiple buried victims under time pressure, the BD Guide BT Beacon from Black Diamond operates at 457kHz with a 3-antenna design that reduces signal spikes and improves spatial accuracy during both primary victim location and secondary victim marking. A mark-and-scan function flags found victims and allows the rescuer to continue searching for additional signals without losing track of already-located positions, and an auto antenna switch automatically optimizes signal transmission without requiring manual adjustment between send and receive modes. A built-in inclinometer provides continuous slope angle readings during the approach and search, and Bluetooth connectivity pairs with the Pieps app for settings management and firmware updates without needing to bring the beacon to a service center.

At 225g powered by 3 AAA batteries with 400 hours of transmit life and a 60m circular search range, the Guide BT from Black Diamond is the appropriate transceiver for guides and rescue-trained users who need professional search functionality in a beacon sized for daily carry at 115 x 75 x 28mm.
