Hinge on binoculars is too loose

Here are the steps to collimate your Nikon Venturer II10x23 6.3 degrees compact binoculars:

1. Adjust the diopter: The diopter adjustment is usually located on the right eyepiece, and it helps to adjust the focus of the image for your right eye. Close your left eye and adjust the focus of the right barrel using the diopter adjustment until the image is clear.
2. Look at a distant object: Choose a distant object, such as a building or tree, and focus on it using both barrels. Keep your eyes on the object while you perform the next step.
3. Adjust the barrel alignment screws: The barrel alignment screws are located on the hinge that connects the two barrels. You may need a small screwdriver to adjust them. Use the screws to adjust the alignment of the barrels until the images in both barrels are aligned. If the image on the right barrel is above and to the right of the image in the left barrel, you need to adjust the right barrel downwards and to the left.
4. Test your binoculars: Once you have adjusted the alignment screws, check the alignment of the barrels again by looking at a distant object. If necessary, make further adjustments until the images are aligned.
5. Repeat the process: Over time, the alignment of your binoculars may shift slightly, so it's a good idea to check the alignment periodically and make adjustments as needed.

Simple solution: Pry or unscrew the cap covering the end of hinge shaft on the rear of the binocs (between the eyepieces). Use a screwdriver that fits snugly in the slot on the end of the shaft & tighten to desired tension. Place a dab of Goop-type cement on the inside of the cap if it was pried off & press it firmly back on the shaft . Helpful hint: Slide a small knife blade (an old dull one you don't use for cutting) under the cap and gently work your way around to pry it off. Note the position of the index numbers before you remove it so you can replace it in the same position.

sounds like center hinge is loose..has to be taken apart to repair ..larry@reichinstruments

Does this pair have two parallel tubes with a bridge in between?
If it does, then removing the caps at the eyepiece end of each hinge will reveal a grub screw. Tightening these will add tension to the hinge and give you the proper feel once more.

under the bottom hinge cover there should be a hinge nut you can tighten, if i can help further call 5088331232...larry

Hi Ray:
I have Minolta binoculars with the same issue, I believe that I also have the same Minolta model: 10x40mm, roof mounted prisms, 5.6 degrees, waterproof (WR series) and model number j-b35.

Have you found any solution for the loose center hinge?

they were famous for that, because the screwpin that holds the eyepice shaft is metal and the groove that it rides in is plastic, and eventually gets jammed....look where you put your fingers to adjust eyepieces. should be small metal plate in center of hinge(sometimes with bushnell logo) that will simply pry off by using small screw driver,and now you will be able to see if the screw is loose or damaged. good [email protected]

first open and close the binoculars untill they fit you eye width,now adjust left eye with the flat section located on the center hinge,now turn right eyepiece till clear. note: once you have adjusted right eyepiece you only have to leave it in that position in order to focus from near and far.........good [email protected]

on some models the center focus control is located on the center hinge,it should be flat,and not hard to find,if there is no center wheel this is where it should be...good [email protected]

I agree with you on that! I have a feeling they are either Nikon or Leupold sourced. The body is alot like green ring leupold ive seen but the lenses have a magenta multicoating on a lens surface which ive seen on nikon. I'm in the process of looking for the maker of them myself as I need an objective lens. I'm going to call the Cabela's Cust SVC number and see what they say. I've heard the new Euro styled binoculars are made by Meopta.
