Great piece to have in your crevasse rescue setup. Pair this with a self cleaning pulley and you will have your partner/gear hauled in no time.
As a High-rise window washer i use the "DMM" for pulling myself under over-hangs of building, 6',8', 12' over-hangs it doesn't matter it makes it alot easier when i'm redirecting my self under these conditions. I'm buying 6 more.
Versatile biner I never knew I needed
This biner really does reduce friction on wandering pitches and I've used it far more than I ever expected to. Now that it's available in a locker, it's also a nice addition to a glacier kit as an emergency pulley. That being said, if you're really planning to use a pulley, you'd best stick with a dedicated device.
Great for glacier travel and z/c pulley sysytems
I have used these for crevasse rescue and they lower the resistance quite a bit when pulling using the Z / C systems. I think I read where they can reduce resistance 25-40 % vs. standard carabiners in that capacity.
how well will this hold up to water over...
how well will this hold up to water over time? i'm thinking of using it for river rescue (z-drag) and keeping it in my pfd where it would get wet all the time
I think it will hold up well, as long as you are in fresh water. Also, check it regularly and if needed, throw some bike chain lube on it to keep it rolling smoothly.
