Pros: Durable, easy to hold
Cons: Heavier than most other biners
Best Uses: Sport climbing, trad climbing, big wall climbing
The Black Diamond Hotwire was the first carabiners we know of made with the revolutionary "wiregate" design. At first, they scared people. Today wiregate biners are among the most popular because they are light, strong, and reduce gate shutter (the effect of the gate partially opening during a fall). While this carabiner once was the only one, there are now many to choose from. Still this remains a solid product at a good price, and Black Diamond only made it better when the company shaved of 20 percent of its weight with hot-forging technology. The Wild Country Astro earned similar scores to this product across the board.

OutdoorGearLab Editors' Hands-on Review
The Black Diamond Hotwire scored well in most categories. It scores above average for ease of clipping. It held three figure eight knots very well (it's roomy). As with all biners with the wire-gate design the gate is less likely to get frozen shut on alpine routes and the slightly hooded nose helps protect gate from getting inadvertently rubbed/pushed opened.
As with most carabiners with the unprotected wiregate design, the notch gets caught up on the bolt hanger when cleaning steep routes. The notch also gets caught up when racking nuts. If you want a wiregate, but you're concerned about snagging, consider the Wild Country Helium Carabiner or Black Diamond Oz Carabiner.
This is an all-around carabiner light enough for trad or even big wall climbing but just the right medium size to be easily to clipped on a sport route or with a gloved hand on an alpine route.
The Black Diamond Hotwire is toward the good end of value. Not one of the cheapest biners but not the most expensive either. Because it is so popular, you might find it on sale in our Price Finder.
