ProView – Wild Country Revo
This device is designed to operate as any other tube style belay device: you belay (top rope and lead) and lower as you would with a standard tube device. This helps keep the functionality and usability of the device at a very low learning level. The best benefit I found was giving this device to clients to belay me or others with as it operates the exact same as our tube devices with the added function of the back up: lower too fast or climber falls without a hand on the break strand? No worries, the device will lock quite quickly. How quickly? To test this I grabbed a fellow guide and took some whippers. We a tied a catastrophe knot roughly 3 feet away from the device on the break strand side and had the climber take a fall without having hands on the break strand. The device locked on its own after roughly 2 feet or less of rope went through the device.
