FYI. A couple of years ago a guy who had circumnavigated mentioned to
me that his B&G instrument displays were turning dark. My old Nexus-2
displays were doing the same. I actually swapped displays around
because the most important multifunction for me is the one over the
companionway.
I discovered that if the back-light was on I could see them during the
day. That worked for the one at the nav station, so I put the darkest
display there. The one at the helm I just disconnected.
My gut feeling, after observation, was that constant UV was corrupting
the polarizing coating.
After a couple of years, I have noticed that the display is again clear
in the nav station. I also put those little plastic covers over the
displays over the companionway. Perhaps the polarizing coating can heal
itself. I dunno... still watching and learning. I left the covers off
because I was always moving, but my performance cruiser seems to have
become a performance dock condo. It's all her fault.
Anyway, right now I think it's a good idea to keep the covers on.
I don't know why they put polarizing coatings on the instruments. We
all wear polarizing sunglasses. In combination, you end up twisting
your head around just to read the display.
