Wiser Precision BA-7 Sparrow bino adapter.

Most of the twisting loose is improper installation of the strap. The broken strap above looks like it had contact with a rough rock.

Contact with a rock? No. They went into my bino harness after using it once in the field, then into a new SG harness, and when I pulled them out this season to go over gear, it had snapped while in the harness while not being used.

I took my sparrow off my razor hds for the first time since installing, to send them into vortex for conditioning. It was easier to get on the second time, because the loop was already sized and I knew how the tightening/set screw mechanism worked. I love the thing. I can get it so tight I'm almost worried about indenting the barrel.

Mine came loose once when my tripod tipped over from 2ish feet in strong wind. It sucked, but I don't consider it a defect. If anything it might have had a quick release effect on impact, helping to prevent damage to the binos. I will pack the Allen keys on long trips now.

Does anyone know of a lightweight arca plate with the exact same width as the Sparrow? The plate I currently have on my ATC is different enough that I always have to adjust my VA5 head when I go back and forth between them.

How stable is this? Only experience with a similar mount was on a kowa 55 series and was disappointed in the shake. Felt there wasn’t enough clamping force to keep minor vibrations. Not a huge deal, but it was enough I ditched that particular mount.

I sold my SLCs and the rigid mount to upgrade to a rangefinding bino. Since the laser is in the bridge, I opted for the Sparrow hoping it would be steady enough to range out to 600-800 yards AND still fit into a chest pouch. It’s not as stable as a rigid mount and it can loosen up although I only had to tighten it a couple times in the beginning. Since then it hasn’t loosened up again.

It holds my Geovid-R firmly enough to accurately range distant targets and they also fit into a Marsupial bino pouch without any issues.

I’d buy it again.

I purchased one specifically for my Meopta 15x56's because I have narrow eyes and need the big barrels to be touching each other to actually see through them without double vision. I also have an Outdoorsman's stud installed but the thickness of the post spreads the barrels too far apart for me. The Sparrow works for me in that regard but is much less stable. I can certainly glass with it in most conditions but if it's windy it shakes much more than I'd like. My biggest complaint is that I like to set the tension on my tripod head so it holds but I can nudge the binoculars with my nose to move them as I grid a hillside. This doesn't really work with the Sparrow on the Meoptas as it flexes and shakes rather than adjusting the tripod head. That may not be an issue if you use an arm on the tripod head to glass with, but I'm not used to that so it gets annoying for me.

I should note that I don't know how much of my issues are caused by this particular pair of binoculars. They are big binoculars and have a pretty thick rubber armor, which may contribute to the flex I get. I haven't tried the Sparrow on any other binoculars for comparison as I specifically got it to resolve my issue with the Meoptas.
For me, the Sparrow works better than anything else to solve the specific problem I have, but it's not perfect. I'll likely end up with Swaro NL's and an Outdoorsman's stud at some point to solve that problem for good. I took a video to show what I'm talking about, I'll see if I can figure out how to post it.

Looks like Wiser sells an arca plate as well. I have their rifle arca rail and width seems the same as the sparrow when I mounted both on my tripod. Their stand alone plate is probably made to the same width as the sparrow.

That’s helpful. It will be going on a pair of NL 14s. I’ll stick with the stud… I use a RRS so the tension is “loose” on the head.
