Big-wall climbers: Your days of exhausting jumaring up fixed lines are over! The Atlas Rope Ascender will lift a 250-pound load more than 600 feet on a single battery charge, at up to 10 feet per second. Why climb when you can ride? Rig this puppy at an anchor and hauling will be as simple as flipping the on switch. Just be ready to kill the motor when the bag snags on a roof, or you'll be spraying the talus with cans of Olde English 800.
