Talking about flares. I was able to find and buy a Green Laser Flare a couple months ago. My godfather and occasional overnight hiking partner wondered why I'd spend $85 (at Army Clothing sales, so say, about 1/2 off) for a green laser when the red laser was only $14. Later that night when I was painting objects at conservatively a mile away and you could actually see the green beam stretch out there, he was kicking himself for not getting one himself.

Doug did a long write up on green laser flares several years back and the technology is getting better each year.

I love my SPOT2 and its in my basic kit for everything, and my SDU-5E distress strobe light is still my tried and true signal love. But this green laser sure is cool.
