Expensive and always thought it could inflict more damage if it ever became entangled with a person where the one you referenced does not seem as "pointy". Its amazing the leverage you can get if you get a second line attached to the primary. Especially noticed it helping as far as getting people/things to shore quickly. Wonder if fits all bags or just the larger standard ones that I see in their video....
I have played with the Crossline at a SWR class. It is a nice piece, and at a $114 probably a bargain considering the work that goes into one. Funny thing is that we were not allowed to use it in the water, only on land because they have a knack for getting wedged in underwater crevasses and lost (instructors having to cut the line as low as possible, come back at low water and attempt to retrieve them.) The thing that looks nice about the snag plate (besides the price) is that it is always in your bag should you need it...not another assembly to carry around.
I've tried one out a few times and it works great! It gives a good bite on the rope that a plain throwbag can't. Its about 4" diameter and fits in my smaller kayak bag, won't work in the personal waist bag though.
I've heard many times you need two of the reach tools one to rescue the other. The plastic Snag Plate could be broken to release from getting stuck in rocks and at $25.00 not really that big of a deal. I've spent more money than that for a hat that I lost in the river!
