Really interesting informatin Joe. But do they
work better than a visible strobe?


If the searchers are using night vision it's much more effective.

Most can be seen from over 4 miles away.

Our troops use them to mark positions, no one can see them unless they
have night vision.

Have you seen the IR strobes?

Perfect for thermal vision which is what the USCG uses.
