Trees, Rescue, Rock - All Good.

I've used these ascenders for many years. Super strong - they've even held 2 people during a botched rescue operation.



The locking mechs. are not as easy to work as I would like, but they're very secure. Clip a biner above the cam and it CAN NOT come open while on rope.



I like all the options for attaching 'biners and slings too.



My only complaint is the handle size. I don't have giant hands, but the handles are a bit small for gloved hands.

Sturdy and nice

I've been using these regularly since last May, as part of a yo-yo system or part of a Texas system for research and recreational climbs, especially in tall white pines.



These are sturdy, smooth-working ascenders that easily grab a wide range of rope sizes and types. I find the handles comfortable and easy to grasp (Gary Storrick in his review of these complains about the handles - I suspect his hands are a good bit bigger than mine). They're machined from a thick extrusion, and the beefiness inspires confidence - I don't imagine I'll ever wear them out in my lifetime. They're somewhat heavier than other ascenders I've handled (Petzl-type stamped frame ascenders), but only by a few ounces. I find the safety trigger on Petzl type a bit easier to use than the CMI safety, but that's mostly a matter of what you get used to.



Unless I decided to be a weight-reduction fanatic, I don't expect to be in the market for any other ascenders any time soon.

CMI "Ultrascender"

These are the only Ascenders I ever used and owned. Mine are about five years old and still in very good shape. They are reliable, I trust them with my life (literally). It took a few climbs to learn to used them properly and efficiently until I figured out the proper size of the straps to use with them. I do not climb very tall trees so I do not use them that frequently but they are very efficient in tall trees. I have never had problems with them coming off the lines suddenly but have read some info on that topic caused by possible operator error. I think they are a good tool to have in the arsenal of climbing gear we all accumulate as we progress in climbing experience.
