I have bookmarked that great link. It is nice to see a link that supports what SFRX is doing.
The link clearly demonstrates companies are developing new technologies, tackling problems partially solved, or improving existing technologies.
After reading a few articles and seeing the new products, I do not find it hard to believe that SFRX has the ability "to develop and manufacture multiple advanced underwater sensor platforms for detecting, 3D mapping and identifying shipwrecks, artifacts, and metals, including non-ferrous metals.a new way of searching for artifacts."

To think that technology has matured to a point that there is no improvement is naive at its core.
Thanks for the link.
