I'll have to look. They were a birthday present and were whatever the top line 
West Marine binoculars were at the time. Any high quality 7x50 set with good 
coated lenses will make something you can just maybe barely see stand out plain 
as day. Obviously rain, fog, pitch dark, and looking into moonlight will defeat 
them.  Some people think "moonlight = good", but only if it is from behind you! 
 What I need to do is train my dogs to point and bark at unlit markers. I asked 
our vet why they can run full speed in the woods in the dark and he said dogs 
and cats see about as well as a human with night vision goggles on. Speaking 
off night vision, I rarely use any kind of spotlight. I do much better with 
making sure my night vision stays sharp. I have red LED lights for everything - 
there is NO white light allowed after dark. Something I learned when I was 
flying out of an unlit grass field is to look "off center" and kind of scan 
besides what you are looking for. Human vision is much more light sensitive 
off-center than straight ahead.

PS - Another night vision killer is the various plotter-computer video 
displays. Make sure you can turn it down! I have seen powerboats go by at night 
with the helmsman's face lit up bright as day by all the screens that he was 
looking at. I doubt he could see the bow!
