Review: Edelrid Giga Jul Belay Device

The first few times while switching modes, I had to pay close attention to the diagrams on the device. Also, feeding rope while in brake-assist mode was initially clunky, and my partner rained vulgarities upon me after I short-roped her at the crux of a Boulder Canyon sport route on day one of testing. However, even though the Giga Jul has the longest learning curve of any tube-style device I’ve used, once I was up to speed I loved its multi-functionality. (Watch the online demo videos and test it in the gym before more serious missions.) I also dug the thoughtful hybrid construction: The main body is lightweight aluminum, while the parts that see the heaviest use are robust steel. Compatible with ropes from 7.1 to 10 mm, the Giga Jul is an awesome belay/rappel device—it’s by far the most versatile one in my quiver and never leaves my harness.
