Back from the future.

Nobody got hover skateboards or shoes that tightened automatically last year, but climbers got Black Diamond's RockLock Magnetron Carabiner, and that's just as revolutionary. Using two magnetic lockers, this RockLock offers an automatic, secure lock that stays secure for seasons of sandy, snowy sending. They also open easily with either hand. Black Diamond designed this locker with a keylock nose for snag-free unclipping, a curved spine for a larger gate opening, and a square hinge to hold your belay device in place.

Pretty cool!

  • Familiarity: I've used it several times

I just like the magnet. Definitely not a necessary piece of gear but it is kind of fun to have. Very easy to use and safe. Even thought the magnet is automatic make sure you always check it when belaying. Its just good practice.

Revolutionary, with some issues

  • Familiarity: I've used it several times

This thing works wonderfully most of the time. I got it because I was looking for a medium sized carabiner that I could easily open with one hand, for belaying and using on the end of my personal anchor sling. Since I'm also climbing in the winter conditions I wanted something that would work well with a single gloved hand as well.

Winter is the problem here. The magnetic contacts tend to ANNOYINGLY freeze up in cold weather, virtually locking it to whatever it's attached to (this could just be to the gear loop on your harness as a best case scenario, or a fixed line that you've attached yourself to and now can't get off). And suddenly I turn into that weird guy who's been banished to the back of the line, sucking on a carabiner to get it to melt and open. That takes longer than you'd imagine sadly.

So I'll be keeping this thing for my summer adventures (because it's USUALLY a joy to use), but in winter and spring it'll be staying home in my gear bin.

Hard to open

I got this Carabiner to make use almost exclusively for belaying. My gripe with it is that it is difficult to open with just one hand, which is really all I needed this Carabiner to do.

favorite belay biner

I love this carabiner. This is my second one of this type, and I must say this color scheme is bomb! They're super easy to use - and I've never had any failures. I primarily use this for belaying, and I'm not sure I'd want to use it for anchors/canyoneering - it seems like dirt and sand could clog this up and cause failure. I love not having to futz around with screw gate biners every five seconds when belaying.

Ease of use.

Great size and shape. I generally use them for building anchors with the rope. They are especially nice because you can rotate them 360º through some chains and some bolts.

Looks cool. Always locked.

This is my second Magnetron (my first got swiped). The new matte black finish looks great so keep an eye on yours! I use this locker to belay in the gym. Super-safe. I took my first one on a couple of trad outings. It worked great but I didn't like getting it all scratched up. The release levers are probably a bit hard to manipulate with gloves so I don't use it for ice climbing.
