Can you take two USGI 3x magnifiers and put them on each RNVG objective lens to create a 3x Bino? Or, are the objectives too close together that two 3x magnifiers would hit each other?


Thank you!

Not a dumb question and the answer is yes but how well it works depends on your IP distance

Yes, but will give you killer headache after a little. It magnifies any collimation issues and any flex in the system throws it even further off.

Is it even worth trying to use two at a time or just use one?

My uses would be scanning a field while hunting, and then immediately popping it off.

different angle - get cheap PVS7 w/ dedicated 3x or 5x glass.
by far my favorite NV "binocular" for scanning at distance and
gives you a loaner / 2nd set that can run at 1x if needed.

to be at least a bit helpful:  2 USGI 3x magnifiers, closest IP
distance without caps would be right at 2.4 inches

100% this.

Also, get a thermal for scanning, it will make your life easier.

It works. The minimum IPD is somewhat limited. I had to remove the protective caps to make it work well. Otherwise no issues encountered yet. I run this set-up occasionally with ANVIS goggles for stargazing.

Quoted:


Honestly if you're going to do this, then I would agree that this is one area where a PVS-7 would actually be a superior option.

No collimation error, no potential IPD interference, lighter when compared to sticking two magnifiers on each tube, and the "flatness" of the image is not really going to be an issue when used for observation at a distance.

That being said, you could also always just use one magnifier with the slip-on cap (instead of thread-on) and close your other eye to observe/scan, and it would be functionally the same as using a PVS-14 with a magnifier [as if hand held], rather than purchasing a PVS-7 solely for this purpose.

I have one 3x now, and still a couple months from my TNVC RNVGs from coming in, but that's what I planned on doing to start.  I was just wondering if I found another USGI 3x at surplus prices, if I should jump on it.  

I plan on getting a thermal monocular next (Hogster), so I would rather avoid having yet ANOTHER handheld in a PVS7 to carry around while hunting.
