or most likely known by some other name. You mount them on top of the mast (they do need some power), and they send out a signal that pops on a radar screen so that a fiberglass sail boat is much more clearly seen on the screen of another vessel. "Sea Me" is one. But I think there are others as well. Does any one know the names of any others and does anyone have any experience with them?

Thank you in advance for you thoughts.
