I was trained on the old military signal mirrors that had a double sided mirror. The new mirrors I see have a sort of grid in the center, but no mirror on the "back" side.

How do you use these? Can you target well if the sun is behind you at 30 degrees elevation and the target in front of you at 30 degrees?

It seems like they would work ok if both the target and sun are in the same quadrent.

I have used a signal mirror a lot in "serious" situations and would not be without one. But using one without the "back" mirror is a mystery to me. Anyone know of a link to a direction sheet for the "grid" type mirrors??
