Black Diamond Magnetron Gridlock Carabiners.
The Black Diamond Magnetron Gridlock Carabiners are revolutionary and a must-have addition to your climbing gear. With the trademark Magnetron technology, the gate uses two magnetic arms, with a steel insert to hold it securely. This easy-to-use system comes with auto-locking technology and the entire mechanism can be operated with just one hand in case of emergencies. The all new hot-forged construction also enables the unique gridlock shape, critically trapping the belay loop and eliminating rope interference and cross-loading. The I-Beam spine helps to provide greater tensile strength and ensures a smooth and continuous rope feed. The harness is lightweight at only 3 oz. and sturdy with an open gate strength of 1,798 lbf., making it durable and easy to carry. The Black Diamond Magnetron Gridlock Carabiner is a thing you can always depend on while mountain climbing.
This product can only be shipped to U.S. addresses.
Featuring Black Diamond's new magnetic locking mechanism, the Magnetron GridLock carabiner brings a new level of ease and safety to belay-specific carabiners. This unique gate design doesn't freeze in the winter and doesn't clog up with sand and dirt the way a screwgate does. In addition to the one-of-a-kind gate, the Magnetron GridLock also has a separated bottom and top so as to completely eliminate the chances of cross-loading, because this is one piece of gear that absolutely cannot fail. To further ensure that its safety, Black Diamond hot-forged this carabiner to make it as tough as it can be. As a final touch, this carabiner also got a keylock nose to eliminate snags when you're taking your friend off belay.
The reinvention of the auto-locking carabiner has arrived. The Black Diamond Magnetron GridLock Belay locking carabiner uses magnets for secure locking and unparalleled ease of use.

I've used this biner a decent amount as a belay biner, primarily with a GriGri 2, and it does its job quite well. The spur totally captures the belay loop, and the magnetron locking system is reliable, quick, and easy to use.
When using this product with a GriGri, the manual recommends capturing the belay device with the spur and leaving the belay loop in the larger opening. This does result in an extra step or two when attempting to take your partner off belay, which is a tad fumbly and obnoxious. I also feel way more likely to drop my Grigri, and probably would not take this multipitching.
I recognize that these are setbacks of the Gridlock, and not the Magnetron locking system, which I like quite a bit despite its added weight.
Also obnoxious about the gridlock is the way that it hangs awkwardly from a gear loop. Blech.
All in all, the Magnetron is super nifty, and works really well, and the Gridlock has its place. This would be a great 2nd belay biner especially safe and foolproof for sport climbing, but I'll keep using a vaporlock or attache screwlock for multipitch.
I have been using this for canyoneering since November 2012 and I haven't had any problems with it till June 2013 when the rope would get wet then sandy in the Zion canyons. While rappelling your carabiner and ATC help clean off the sand from the rope but some sand ends up getting under push tabs of the Magnetron and make it so it freezes up and stays locked. You have to really play with it to loosen up the sand if you don't have water to wash it out with which sucks since this biner is not supposed to freeze up with sand. I haven't had any problems with it not locking though so that is good.
Overall I highly recommend the Magnetron to canyoneers, but if you are in super sandy conditions and using an older rope that holds sand well, beware of it freezing up just like any other locking biner.
The gate on the magnetron has the magnets in the gate and when it closes it locks into groves. It can be opened with your finger and thumb just fine.If I did it all again I thing I would get the rocklock version. The gate locks every single time you close it because of the magnets, so it can get annoying to open it to put you gear in, close it to slide the gear down, and then open the gate again to move the gear to the bottom to prevent cross loading. Seems to be quality materials though! I have not had any durability issues.
I love the gridlock, but am less enamored with this one. I like the idea, but it doesn't operate as smooth as I would like it too. I haven't used it in a canyon yet, but hopefully that will change my mind.
