I love my BD jumars, use them in preference to Petzls on any rope access gigs, gym work, and aid that I happen to do. Never had any slippage, but to get the teeth to cam properly, you need to not be pulling 'outward' with your hand when you slide it up - which I suspect is probably the root cause of most of the complaints about this. Love the quick trigger system, and the top bump for disengaging the teeth/down-jugging, much easer to use than the Petzl, especially with gloves on. Can get them on the rope and off much quicker than the Petzls, and find them more comfortable to grip. The big biner hole is ace too, and when using them on a scary mud/concrete-slush soaked rope on an access gig one time, was stoked at the grip they had.
The torquing of the device/popping off issue, not that I'm an expert by any means, but I would assume that problem is common to all jumars? : / And if I was doing a traverse line, I'd just clip a biner through the top holes to prevent the jug popping, which is why they're put there in the first place!! Funny that no-one mentions that crucial omission on the Supertopo thread...? Not sure of the hysteria being generated about the BD's, I can't imagine a company like BD putting out anything on the market as fatally flawed as what is being made out! (Or I hope so anyway, otherwise my ass is in trouble! : )
Yes, they're slightly heavier than the Ascension, and the Petzl is a cool jumar as well, but I'd use my nForce any day over another jug! |
