Greatland Green Rescue Laser can be seen 30 miles by an aircraft searching for you. It costs $249.95. You could select the red laser which can be seen for 20 miles and only costs $109.95, but if I’m floating in the water or down in the wilderness I want my best chance of being seen. I will never fly without it!

The beauty of the laser is that it lasts for 5 hours, much better and safer than a pyrotechnic flare that is done in a few short minutes.
