Trango Cinch Belay Device - $77.36

Giant whippers and never-ending hang-dogging sessions aren't an issue thanks to the Trango Cinch Belay Device's assisted-locking mechanism. If your partner goes for a really big ride, then the Cinch acts dynamically instead of locking down solid, which provides a softer catch and lowers the impact force on gear and on your partner. After the ride, your climber will get a nice, smooth lower thanks to the precisely designed cam. Perhaps most importantly, this belay device works on ropes down to 9.4mm so you don't have to change devices just because you're using a lightweight line to send your project. - $77.36
