WTK - DDR binos

Picked up a pair of DDR binos at a gunshow.

I get the dovetail is for a recticule illuminator. The switch rotates a cover inside to block the eyepiece that does not have the artillery reticule. What's the glass plate on the right?
I don't know much about them, except they are noticeably clearer than my Steiners. What might they be worth?

Thanks - any idea how it works? Shine a light into it to activate some phosphorescence?

Sorry, I do not know. Needs an illuminator of some sorts. Here are more links for info:

"detector for active infra-red sources, which is charged by the UV contribution of the daylight. "

Cool - I will play with it sometime - see if the IR illuminator on my PVS-14s will show. Thank you so much for the great links.

I paid $225. Not my field of expertise, but I am not disappointed.

I was cleaning my Steiner 10x50 Military Marine and I noticed what look like fine fiberglass splinters clinging all around the inside of the objective tubes with a few clinging to the inside of the objective lens. I have a service ticket opened with Steiner. I find it interesting that, at least from my perception, the 7x40 DDR produced, seem brighter than the 10x50 FRG produced binos. So much for Comblock being crap.

And while I haven't called artillery or mortar fire in the last 30 years, the mil scale is kindof cool.

I think even the remote for your TV would work as an infrared source.

FWIW a pair just like those sold for $300 on eBay last December. I'd say you did fine.

The Osties made some nice glass in the old Zeiss plant in Jena.

I was thrilled when Apex was selling sets of these for $90 about 5 years back. They sold out quickly. Very nice binoculars, and heavy!

Well, Steiner is screwing me on their warranty. While their current warranty is lifetime, that only started in 2014. Mine were made in 2004 and only carry a 10 year warranty. There are hundreds of what look like fiberglass insulation shards clinging to the insides of the tubes and a few on the inside of the objective lens. Seems to me something on the inside is deteriorating. I certainly didn't put them there.

My suggestion that such an obvious factory defect should be repaired without a time limit, has so far yielded nothing more than "that will be $130 to clean and collimate".

I will make one more call to Jeremy, the repair manager, on Monday, to see if I can get them to repair their defect at no charge to me. I am hesitant to pay such a high percentage of the optic value, fore what is so obviously a manufacturing flaw.

Gee - sorry, I don't use them every day and only got the idea there was something wrong with them, when I compared their clarity to the DDR ones.

I was watching 13 Strong last night (Thumbs up) and noticed the team from 5th SFGA was using these Military Marine binos, although theirs had the artillery reticle. I think they call them M22. I learned fire support off ancient M17? binos.
