Practical Sailor had an interesting article about a laser device used
as an alert/locate device for ppl in distress. Basically its a 5 mW
laser diode with a plastic line generating lens. They say that it has
to be held to sweep the horizon and jiggled slowly and that it takes
practice before it is needed. ///

I have had one of these for over two years. It does not need to be
"jiggled" slowly to be noticed. It sounds to me like the person who wrote
the article may not have tested it.

It sounds as though Scott may not be aware of the impact of a flashing
light. Some aircraft use double flashing strobes for this purpose.
No more power, but more eye-grabbing.
