Does that nitrogen really stay inside those binoculars.
 

My Fujinon binoculars are at least fifteen years old
now and still working like new though they look a little
beat up.

Amazingly they do not fog up inside the lenses.

They are filled with "dry nitrogen" at the factory
but I find it hard to believe this inert gas has
stayed in there over all the long years.

Anybody here happen to know how long nitrogen
really remains in those filled binoculars?

CN

Forever, and some O2 and trace gases as well!

You can open them up and find out.

My Stieners are guaranteed for life.

And when they leak, the life (and guarantee) is up!

All gases will leak out over time. How long it remains in depends on the
type of work you do with them. Aboard aircraft, and at high altitudes they
leak faster. Drop them and they may leak. Heat them up and they may leak.
Cool them too much and they may leak. Note all the optics are in a nitrogen
atmosphere either. Send them in for service every ten years and you'll be
fine.

A sensible answer among a bunch of assumptions.

Thanks for the rare find . . .

I doubt that it is even worth a service on such binoculars (given labor
coists etc). It may be just cheaper to buy new.

Fujis cost 7-800 bucks. They are rated better than
Steiners in Practical Sailor tests.

A little maintenance cost would be cheaper than buying
new ones. Plus, they have a lifetime warranty.

Hey, man, you sure are looking small in your discourse
with LP. You should give it up. A real man should avoid
being constantly made to look silly by a woman.
