PROBLEM: Numerous Ice Rescuers have reported to MARSARS that their water soaked tether ropes froze fast to the ice. These infrequent incidents were caused by freezing conditions that also would freeze a locked carabineer’s locking mechanism. Without an emergency means of detachment (knife), your rescuer may not be going very far.
SOLUTION: When failure is not an option, use carabiners that open when frozen and carry a knife. That’s why all MARSARS Ice Rescue Reels and Tether Line Bag Kits feature this stainless steel carabiner and thimble.
