Binocular Tripod Adapter, Binocular Mount 1/4 Inch Threading Mount Aluminium,Tripod Adapter for Bird Watching, Safari Sports Events, Optics Uni-Adaptor Tripod

The adapter is sturdy enough for a medium weight binocular and is designed to allow plenty of clearance. The only gripe I have is that the length of the cylindrical hub at the business end prevents the threaded washer or flange from fully threading onto the thumbscrew when assembled. This makes the flange act like a locknut and interferes with tightening the screw onto the binocular. I ended up filing the hub to about a half inch long, 13mm or so. The flange will then thread on until it's clear of the threads and engages the shoulder of the screw, making it free to rotate independently. Then mounting and dismounting is easy.

The media could not be loaded.  Overall, this adapter is sturdy, well polished. But mine came with a washer flipped. Though this assembling mistake is annoying, it is easy to fix. So I still give it five stars for its quality.If you were to receive an problematic adapter like mine, you need to fix this small problem in order to use it. I will talk about this at the end of this review.Obviously this metal adapter is more expensive than some plastic ones. Do they worth the price? I would say this is a good product but plastic ones are not bad too depending on your need.My friend has a plastic binoculars adapter. After buying this, I compared them. Both seems quite sturdy for my 8*42 binoculars and my friend's 10*50 binoculars. With a decent tripod, we saw no vibration on pan/tilt but you can manually roll the binoculars. If you want to fasten the binocular in rolling direction too(for example, attaching a phone or camera while keep binoculars level), both cannot do the work.We don't have large binoculars like 60mm or above, I have no idea whether a metal one would be a must for heavy binoculars. Anyway, if you do have high power binoculars, at least you need a $100 tripod to support it otherwise you are going to get shaky image.Here are my thoughts:1. A well made plastic adapter might be as good as this for small binoculars if you have a sturdy tripod2. If what you have is a flimsy tripod, honestly, this metal adapter won't help you. The problem is your tripod.3. If you have already spent more than $100 on a decent tripod like I did, I think the price difference between this metal one and other plastic ones is acceptable. I will go for a metal one just for assurance.4, If you have already had a good plastic adapter, a good tripod and you don't have high power binoculars, I don't think you need to upgrade to a metal adapter.5. If you need to attach a camera to one side of your binoculars, this might not be the one for you.Talking about the washer problem. A washer is a plate on the bolt to distribute the load. On this adapter, they have a thick washer. The problem is, it is asymmetric. So if it was accidentally inverse, it will stuck and you cannot fasten your binoculars.There is a rubber washer and a metal washer. You need to remove the rubber washer to reveal the metal washer. If it is properly installed, you should see the metal washer with a pit facing you like my photo. If you see a flat face, you need to flipped the washer. Simply screwing it off, flipped it, screwing it on will do it.I wrote to the manufacturer about the washer problem, they were happy to hear from me and wanted me to post this in my review so that others can know how to solve the problem. I found my instruction was not intuitive, so I recorded a video to explain how I flipped the washer using my phone.

This is a nice adapter but the screw end is a little long for my Vortex 10/42. I needed to shim the adapter screw and now it works fine.

I ordered a large pair of Celestron binoculars (15x70) and every review said they were great but the tripod adapter was flimsy plastic, so wobbles. Video reviews show it happening. The entire point of mounting binoculars on a tripod is stability. I looked at both Celestron and other replacements, and this one was listed as metal. I asked in Amazon Answers, and the replies said it would work well for these binos. Well, the adapter arrived before the binocular and tripod, and it's rock solid. The screw for inserting into a binocular threads right up to an existing pair I have, and a 1/4x20 bolt threads into the tripod end just fine. Unless something doesn't somehow work once the other items get here, I'd say this is perfect, and highly recommend it. ....oh, and the plastic name brand one is $18.99, and this one is $12.99, so that's a bonus. Skip the plastic garbage and get this one at a better price. ...oh, editing to add the following: no way does the washer being installed backward deserve a star taken away from ratings. It's a washer. If yours comes installed backward like mine and others' were, just hold it and un-thread the bolt, flip, and reinsert. Gimme a break!!!

This seems to fit and work OK. It took some fiddling to get it to tighten up properly, but it tightens up OK once you turn the metal washer around so the counterbore in the washer is facing forward, not toward the binoculars as it comes from the factory. This lets the washer turn freely, independent of the attachment screw. See the excellent video made by another purchaser, WX, if this isn't clear.Otherwise, it seems to be a good device, and it costs half as much as the same thing from Vortex. Both made in China.Made of aluminum, not plastic, seems well made. Should work fine.The only drawback to the design is that, because it's a bit of a pain to install and remove the adapter, you will have this metal thing hanging down between the lenses when you take it off the tripod and us it handheld. And if you have a bag you put your binos in then you're not using them, the binos are not going to fit into the bag with this device on them.When it's on as tight as you can get it with your fingers, there's still a bit of rocking play left in it, but it's pretty secure and stable.

DOES IT'S JOB BUT IT'S A TIGHT SQUEESE (close Quarters) not a fast mount up or take down. Have to be real real careful not to break it off when not mounted on the tripod. Going to make a quick disconnect lock on for mine. DOES IT WORK YES. MAKE A TOOL. Get a 1/2''or 5/8" dowel rod 4'' to 5'' long . CUT A SLOT IN ONE END (like a screwdriver slot BIG ENOUGH TO FIT THE MOUNT SCREW) THIS MAKES LIFE A LOT EASY FOR YOURSELF SHORT OF LONG NOSE PLYIERS FOR A EXTENDED REACH.

I used this on a 8x42 Wingspan binocular. The depth of the threaded hole was pretty shallow, so the binocular wasn't stable on the mount--it would rotate around the a threaded shaft. This is not normally a problem, but I was using an attachment to the binocular to hold an iPhone to record the launch of a Falcon 9 at the Kennedy Space Center. I tried adding washers but there wasn't enough friction to prevent the unwanted rotation. I finally bought a ¼-20 x ¾" long screw (button head cap screw) at a local hardware store which fit properly and I could tighten enough to make the whole setup stable.

After bought and then returned Carson TA-50 and Barska binoculars tripod adapters (both having hundreds of 5 star ratings), I finally settled on this noname mock up of Vortex adapter that only has tens of reviews, just to give it a try. To my surprise, it simply works! The price is much lower than big name products. For such a simple part, it's definitely more bang for your buck.One trick to mount the adapter is to rotate the screw knob counter clockwise first to leave only a few turns of threads exposed. This leaves enough room to turn the knob clockwise until the adapter is fully tightened to the binoculars.Since I just started to use it, the longevity remains to be seen. That said, it's made of a solid piece of metal (aluminum?), so I'm not worried about it.What was wrong with the Carson TA-50 adapter? There's only 2 or 3 turns on the screw, and the adapter easily rotates even after I fully tightened the screw. It may work on some binoculars, but not on mine. How about the Barska adapter? The knob on the screw is simply too big. It barely fits the space between the lens, making it difficult to rotate. The adapter rotates easily even after I fully tightened the screw.
