To be honest, two facts:
One, you don't really need polarized glasses when fishing from a boat unless you are sight-casting in the shallows. (In which case you aren't using your fish finder anyway.) Just standard tinted lenses are fine.
Two: With few exceptions at the high-price end of such units, fish finders have plastic screens which are notorious for "blacking out" through polarized lenses. Dashboards, gas pumps, and even some phones have the same problem.
