Don't your competitors have running lights???? Learn to read their
navigational lights and you won't need a night vision scope.

I'm going to be in an all night race and expect to be sailing back in the
direction of other boats coming right at me.

I thought a night vision scope would be handy, but someone told me only
the
very expensive ones can see half a mile or more. Most can see only about
100
yards which is a short time when two boats are coming at each other on a
collision course.

Anyone have any experience with night vision scopes on the water?

Thanks, Dennis
