Product Description: The Petzl Reverso is one of our favorite belay devices for multi-pitch climbing. It&';s the lightest option for this style of device, and if you use skinny ropes, it is likely the best option. It uses a standard tube-style design with an extra clip in point to orient the device perfectly for use in auto-block mode belaying a second off the anchor. It really shines in multi-pitch situations, where its versatility for use with two ropes, while lead belaying, rappelling, and belaying the second in auto-block are all highly valued. It also functions great for single pitch climbing, and is more versatile than the similar Petzl Verso, which isn&';t capable of belaying in auto-block mode. REVERSO is a belay device for single or multi-pitch climbing and mountaineering. It allows you to belay your climbing partner, rappel, and use Reverso mode to belay one or two seconds. The specific design allows the rope to glide smoothly through the device and reduces wear. Features: Feeding slack and catching falls are accomplished using standard belay techniques, always keeping a hand on the brake side of the rope Rope glides smoothly through the device V-shaped friction grooves enable controlled braking Rope installation diagrams for belaying and Reverso mode are engraved on the device Multipurpose use for single and multi-pitch climbing, and mountaineering: Can be used to belay a climber or to rappel on one or two rope strands Reverso mode allows the user to belay one or two seconds with assisted braking Release hole allows the belayer to give slack to a second climber using just one carabiner Lightweight and durable: Compact and ultra-lightweight: only 57 g Rounded design of the rope slots limits wear and extends the life of the device.
