Haloview MC7611 viewing with polarized sun glasses

Thanks all,

I know I need polarized out on the water. Are they not particularly useful for highway driving?

Wouldn't you expect the polarization direction to be standardized in such an important application? For example, my flat screen monitors I'm using now look fine with the polarized sun glasses, but get dark when I tilt my head over. That is the opposite of the Haloview. Perhaps they are using a generic screen that is normally vertical for fish finders or something.
