The Black Diamond HotWire and Black Diamond Livewire were some of first carabiners with the once revolutionary "wiregate" design. At first glance, the wiregate looks weak and fragile but after reading the specs and seeing them in action, it is no surprise that wiregates have become the default carabiner design. Fast forward a decade and there are a lot of competitors to the Livewire but it is still on of the best carabiners clipping the rope to while sport climbing. Black Diamond recently made it even better by adding a wire hood around the notch that prevents the nose from snagging.
Black Diamond LiveWire Review
Cons: Not light, toward the more expensive end of biners
Manufacturer: Black Diamond
Our Analysis and Test Results
This scored high for ease of clipping. The ridge and gate are easy to grasp and manage during a clip. With a deep basket, this binner accommodates multiple ropes if used at belays. The hood adds a little weight but also means it's less likely to get snagged when unclipping.
This is a heavier carabiner. If you are climbing with a big rack of draws you notice the difference between this and an ultralight biner.
This is mainly intended to be on the rope-clipping end of a quickdraw. You can buy it separately and make your own quickdraw with another biner or buy the Black Diamond Livewire Quickdraw.
These are in the middle range of price. They are not cheap but not extremely expensive either.
