I'd love to know the difference in distance visibility between a upper-end LED light (like a Fenix or Surefire single CR123 version) in flashing mode and a Greatland Rescue Laser Flare.

I have both and would like to test it, but unfortunately I don't live near mountains nor do I own a helicopter (darn!). The single CR123 LED lights are VERY bright and much smaller & lighter ... and of course more multi-purpose.
