Man, I’ve been busy lately. It’s just non-stop work, work, work lately. These sorts of episodes of high-demand don’t happen very often (thankfully) but when they do you have to strike while the iron is hot. So..this is why I haven’t been around much lately. however, that doesnt mean that there arent things going on…….

I picked up one of these the other day to go along with the marker panel from the same outfit. It’s made of glass (albeit thick glass) so it may not be as unbreakable as other signal mirrors out there but its hard to beat the reflectivity of a good glass mirror. I’d been shopping around for a signal mirror to put in my little survival kit for when Im hunting/fishing and I just wasnt finding anything that I really thought was any good. I picked up a few of the non-glass mirrors from countycomm and while they would probably do the job, I have a hard time finding anything thats as good as old-fashioned breakable glass.

I need to do some empirical research and see just how visible these mirror flashes are at a distance. next time the wife takes the dog for a run up the nearby mountain I’ll have her call me from the top and tell me if she can spot the flashes from up there. I would imagine reflected sunlight must be rather highly visible at range since the military used to use heliographs for communications.
