Neodymium Filter History

Hi Joseph,

Actually, the Neodymium filters go back way longer than 25 years. I'm an avid reader of history, particularly that of u-boats. I was surprised to read the the Germans used neodymium filters with their binoculars to enhance their ability to see signals from Morse lamps from other boats.

I wish I had that book with me, so I could find the passage.

BTW, I was in a building yesterday that made me think of Detroit, only it's much, much closer to home. It was a fun day!
