Laser Sonic Ice Screw

The Petzl Laser Sonic Ice Screw is the latest innovation in ice climbing anchors, and perhaps an attempt to push the envelope beyond the current leader, the Turbo Express. The Laser Sonic is designed with a rotating hanger and crank-in-one for ultra-efficient placement and removal. For the leader, placement is possible with one hand. The aggressive teeth bite into the ice for optimal penetration in as little as one and one half turns. The increased angle of the hanger away from the head of the screw means less effort scraping away ice and a quicker overall placement time. During cleaning you can leave the screw clipped to the rope, reducing the risk of dropping the screw.
