For a fairly good photo of the speedhook, try
www.bestglide.com. I've got two of the military versions bought from Brigade Quartermaster (see their website also). They're all that they're advertised to be, even if a little pricey, although after seeing the bestglide site I might just have to pick up a couple of the civilian versions (two to a pack, without the line and bait and more reasonably priced).
