Rack up with the Dynotron.

With a large shape and a new lighter weight, the hot-forged Black Diamond Dynotron Carabiner makes for easy clipping whether you’re sport climbing in Rifle or hacking ice in Ouray. The keylock nose helps avoid rope snags, and at only 1.6 ounces, you can afford to take a few extra.

sexy recycled sprite bottles?

My all time favorite bolt side biner for draws. Kink in the spine make for a larger gate opening and keylock nose allows easy on and off, super nice when cleaning really steep routes. Overall a bigger biner so it is a bit nicer on your rope. The overall feel of this biner is super sleek. If you have a friend with these biners do not use them unless you are ready to buy some yourself. Once you have felt the goodness there is no going back.

Weak Biner

I'm with Simon on this, the gate is too weak. It's an ok biner and I use it now and then, but it's definitely way down the list when I'm pulling gear out of my bag.

Beautiful, but imperfect

This carabiner has the expert craftsmanship I've come to expect from Black Diamond. I bought it specifically to rack my stoppers on, as I don't like the standard Ovalwire and wanted a keylock with a big basket.

Pros: Pretty big, square basket. Distinctive (and beautiful IMO) color that makes it easy to ID. Keylock means no snags

Cons: Weak gate spring so it opens accidentally sometimes. Heavy. About as expensive as non-lockers get. Lower basket is not that much bigger than a positron.

Overall, not a bad carabiner, and probably super nice on the bolt end of sport draws (its intended use). That said, you can do better for the dough.


Disclaimer: I only own one of these, which means it is possible (though unlikely) that the weak gate spring is an isolated issue.

Responded on

Racking wires is exactly what I want this biner for. I also dislike oval biners because when they're on your harness you can't tell easily if they're the right way up or not - annoying! Would you recommend it for racking or have you found something better?

Responded on

its pretty great for racking wires, i typically carry about 16, the 7-8 largest on this and the smallest ones on a nitron. its a system I like, but I've never seen anyone else climb with it.

Responded on

Yes, the gate spring is weak. I bought one for racking wires, but I wouldn't recommend it for that purpose, due to the weak gate and narrow lower basket. I've switched to a DMM Ultra O instead.
