The first time I saw one of the Lifelines, I giggled at it- it's compass sucked to. It turned fine, but it was pointing in a vaguely northerly (or southerly) direction. The fact you have a hard time buying a good compass for less than $20 should tip people off.

Calling the PSP a winner by a knockout!

I see short comings in the PSP, I've never hid that (lack of shelter, mostly) , but for the mass market I've only seen one pocket kit that came close. And it's another AMK product. There are others that are as good, but I don't see them at Dicks or Eastern Mountain or the Campor catalog.
