I will admit to be in exactly the same boat as paddy about it <img src="/forums/images/graemlins/smile.gif" alt="" />

There's always a roll of lime green and blaze orange flag tape in my hunting pack for exactly the situation
you describe, and I don't follow a blood trail without. You have a light, you should be able to find the flags.

However you're spot on that the situation you describe is a perfectly good use for a GPS unit. Nothing at
all wrong with that..
