If you’re looking for an adapter, get this one. Seriously, it will save you a lot of frustrations. I like that it’s all metal and connects tightly to my Nikon binoculars. This is the 2nd best thing about this adapter. The 1st is the price.
After buying flimsy plaster adapters, I was excited when I found these all metal ones. And yes, it is all metal with the exception of the screw knob. It pairs well with my Celestron SkyMaster and does a good job keeping it steady. For less than 10 bucks, this is terrific.
This tripod adaptor is very strong & has no flex. I have used it for mounted magnifications all the way up to 30x without any vibrations. It works between most binoculars, whether Porro prism or roof prism.
This is a very good product at a very reasonable price. I own several of this model.
