Rescuers use new tech to save caver trapped vertically in Alberta's 'Psych Squeeze'
The volunteer-built QDX-M radio helped rescuers communicate through rock during a 13-caver, 10-firefighter operation, Search and Rescue Alberta said.
On Saturday, a caver trapped in the "Psych Squeeze" at Rat's Nest Cave in Canmore, Alberta, was rescued using volunteer-built underground radio technology deployed in a live operation for the first time.
Alberta/BC Cave Rescue developed the QDX-M radio system to overcome communication failures with traditional methods like phones and GPS, enabling signals through more than 500 metres of solid rock.
Hammer drills removed rock to extract the caver in a process measured in "inches per hour," involving 13 cave rescuers, 10 firefighters, and two Kananaskis Mountain rescue members over nearly 11 hours.
John Alexander, CEO of Search and Rescue Alberta, called the rescue "a display of what can be achieved when multiple emergency response agencies come together in collaboration," praising the 1,500 volunteers involved.
Such units are not currently available commercially at an affordable cost, making volunteer design and construction essential for ensuring teams can reliably communicate from deep caves to the surface in future emergencies.
