This figure 8 descender is built like a tank and perfect for climbing, rappelling, or rescue situations. The aluminum alloy construction is lightweight but seriously strong - rated for 35KN (about 3500kg), which is more than enough for most climbing applications. The bent-ear design is such an improvement over basic figure 8s - it makes locking off much easier and safer when you need both hands free. The large main slot can handle single or double ropes, giving you flexibility in how you set up your rappel. I've used this for both rock climbing and training exercises, and it performs consistently well. The surface is smooth but provides good friction control for smooth descents. The size is comfortable to handle with gloves on, and the weight (about 124g) won't add much to your gear load. It's versatile enough for recreational climbing, fire rescue work, or even aerial silk performances. The construction feels solid with no sharp edges that could damage your ropes. If you're looking for a reliable, no-fuss descender that you can count on in various situations, this figure 8 is definitely worth having in your kit. It's one of those fundamental pieces of gear that every climber should have experience with.
