Hi, John and Group . . .

I, for one, am a visibility freak - and an astronomy fan.  Any system or ideas that will shed light
('scuse) on u/w vis would be great.  Given the inherent suitability of subs as instrument platforms,
then, some sort of EM system could work.

Question: since poor vis is usually due to suspended matter - which is solid - how do you do a
go-around using alternative w.lengths?  I would have thought suspended matter would behave
differently from atmospheric particles in terms of penetration.
