Watch the size!,  Monday, 10 March 2008 I purchased this helmet to be used for tree climbing, rock climbing, and rope rescue. After about an hour of trying to fit it right on my small head, I decided to return it. Even though the manu. says this helmet's range would fit me, I couldn't make the proper adjustments. It sat too high, and moved a lot on my head.

Later I found out that there is a second size - a smaller size, but most retailers do not carry it.

 Trees, Rescue, Rock - All Good.,  Wednesday, 27 February 2008 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.

 product shown is not product described,  Sunday, 17 February 2008 I am reveiwing the product shown in the photo, not the one in the description. The product in the photo is a KONG RESCUE 8, not a CMI rescue 8.
As a rescue technician, I have owned and used both. I prefer the Kong.

The Kong 8 has a higher strength rating. Kong-40Kn(>8,992lbf), The CMI, I've seen rated as low as 30Kn9(>6,744lbf.) The ears on the Kong 8 are longer than on the CMI, and they have a bit of a hook on the end. These ears provide an easier and more secure lock-off.

This is a multi purpose tool. Because of this item's large opening and high strength, it can also be used as a rigging plate. The center hole/slot can be used as a belay plate to lower branches or even people.

Though it takes a bit of practice and rational thinking to learn to use safely, I really like this product. (The one pictured)

Kong also offers a REALLY heavy steel version rated at 50 Kn! That's >11,240 lbf!
