[Public-List] Binoculars

[George Dinwiddie]

I don't think you can beat a 7x50 on a boat. We have a Nikon 7x50, which 
is probably a little smaller than the Fujinon. It's not rubber coated, 
for one thing.

When we bought the boat, it had a teak box for binoculars, similar to 
https://snuggs.me.uk/content/images/thumbs/0000555_binoculars-holder-teak_370.jpeg, 
just inside the companionway on the starboard side. I suspect it was 
designed for 7x35s, and it's too close to the overhead to put ours in 
with the objective lenses down. But it does go in sideways, and is very 
handy there.

That 50mm objective is what makes them so bright. Divide that by the 
power (7) to compare brightness of different binoculars. Of course, the 
quality of the glass makes a difference, too. Nikon glass has a high 
transmission coefficient. Higher than 7x magnification will be difficult 
on a boat due to the magnification of the motion.

I think I would get a new place to put the binoculars rather than get a 
new pair of binoculars.
