Are there any binoculars out there besides Steiner that use ARDs (Anti Reflection Devices)?


Doesn't matter if they are thread on or clip on.

I'm curious too.

That's a tough one, I haven't seen many although there is one available for Fujinon M-22 7X50.
Sungard offers a variety which fit Butler Creek caps. https://tenebraex.com/sunguards
Carson also makes a universal clip on type.


I took a couple of the ARDs out of a set of "Bushwacker" flip caps years ago because they were a good fit
to my Geovid 10X42mm binocs.  They don't to seem to make these anymore but luckily I have a couple of spares.
I built up the edge to make them fit tightly, haven't yet lost one, plus they don't seem to affect the rangefinder laser.
Plus, they fit well under the Leica caps.
