My 12 x 25 T - IR Binocular is missing the black cover over the right lens next to the focus control knob and the rubber lens protector is missing. How can I get this repaired or would it less expensive to buy a new binocular?

Depending on the brand ( Zeiss, Bushnell which are good quality) the cost of repair will vary. Most Jewellers or camera, or even a camping store can send your bins out for a quote. Spares can be bought for a moderate fee, as the cover caps and eyepiece rubbers are pretty much standard size items ( Estimated cost $20 + labour) cheaper to buy parts and install it yourself. This is not a difficult task aqnd will save you labour cost.

Thanks for using FIXYA

Minolta Compact II Binoculars - the focusing adjustment is seized, how do I free it?


The adjusting knob has a rubber cover over it. Remove the rubber cover and take out the phillips head screw underneath. Then turn the adjusting knob all the way left with a pair of pliers and continue turning and it will unscrew and come off. Underneath you will find a metal lock nut, when you loosen this you will find the adjusting knob is suddenly not frozen anymore. It seems that this nut tightens over time to the point where the whole mechanism freezes. You can take the nut off and put some thread lock on the threads and tighten it just enough and it won't happen again. Cheers.

I see double image unless I take the lens as close as the binoculars can go


thats how binoculars are. Yours in this case is really strong. the closer you are to something, looking at it, the more magiflyed you going to be. try view things far a distance, really far away. no more double right?
Everything you need to know to become an expert:
on this website: http://www.chuckhawks.com/binocular_basics.htm
It is surprising how many people do not know how to focus binoculars correctly. There are two common focusing systems used in binoculars.
The first is individual eyepiece focus. This system is simple to understand, and easy to manufacture. It also lends itself well to sealed optical tubes, and thus is usually the focusing system used for waterproof binoculars. Individual eyepiece focus means that to focus the binoculars to your eyes, you simply focus the left eyepiece to your left eye and the right eyepiece to your right eye. There is no centrally located focusing mechanism. It is done like this. Look at something in the distance. Close the right eye (or cover the front of the right binocular), and focus the left eyepiece to your left eye. Close the left eye (or cover the front of the left binocular), and focus the right eyepiece to your right eye. You are finished, until you need to look at something at a different distance, in which case you need to repeat the process.
Because individual eyepiece focus is time-consuming, center focus is more common. Unfortunately, very few people understand how to correctly use center focus binoculars. Here is how it is done. Aim your binoculars at something in the distance. Close the right eye (or cover the front of the right tube), and focus the left side of the binocular to your left eye using the center focus control, which is concentric with the pivot shaft between the binoculars. (Note: the left eyepiece itself does not focus on center focus binoculars.) Next, close your left eye (or cover the front of the left tube), and focus the right eyepiece to your right eye. DO NOT touch the center focus control while you are focusing the right eyepiece to your right eye. Now you are finished. What you have just done is adjust the binoculars for your individual eyes. (Practically everybody's left and right eyes are different.) From now on, you only need to adjust the center focus control when you look at things at different distances. Center focus is faster and easier to use than individual eyepiece focus, once you have initially set the binoculars for your eyes.
Binoculars are commonly described by using a pair of numbers, as in "7x50" or "8x25." The first of these numbers refers to the magnification offered by the binocular. Magnification is why most people buy a pair of binoculars. In the examples above, "7x" means the binocular makes whatever you look at appear seven times closer than it does to the unaided human eye. "8x" means the binocular makes whatever you look at eight times closer than the unaided human eye. "10x" makes things look ten times closer, and so on. The first number used to describe binoculars always refers to their magnification. Common binocular magnifications are 6x, 7x, 8x, 9x, and 10x.
There are also variable power (zoom) binoculars, such as 7-21x50. These almost always perform much better at the low power setting than they do at the higher settings. This is natural, since the front objective cannot enlarge to let in more light as the power is increased, so the view gets dimmer. At 7x, the 50mm front objective provides a 7.1mm exit pupil, but at 21x, the same front objective provides only a 2.38mm exit pupil. Also, the optical quality of a zoom binocular at any given power is inferior to that of a fixed power binocular of that power. In general, zoom binoculars are not the bargain they seem to be.
Remember that everything (including movement) is magnified when you look through a pair of binoculars, especially your own shakes and tremors. So the higher the power, the harder it seems to hold the binoculars steady. 6, 7, or 8 power binoculars are easier for most people, even those with very steady hands, to hold reasonably still. The higher powers sound like a good deal, but often result in jiggly, blurred views. This is why 7x binoculars are chosen by so many experts, including the military.
Power affects brightness. Other things being equal, the higher the power, the dimmer the view. And power also affects the field of view of the binoculars. Again, everything being equal, the higher the power, the smaller the field of view. So, as you can see, power must be balanced against other desirable characteristics when choosing binoculars.

Yukon Ranger 5 x 42 night vision goggles just stopped working, I put in new batteries, but when I press the ON button the on light, which is red, just flashes maybe 10 times and then all goes black. ???


Hello, let do this. IR illuminator has a montary switch, that is when you push it comes on, and when you release it the IR goes off and it has a red LED to indicate the IR illuminator is being activated.

When you turn you binocular on there will be a green LED activated. This switch is DTSA---double throw sing activated. That is, one throw of the switch it turns on the binocular, the throw will turn off the binocular.

Also within the control panel there is timing circuit to keep the IR illumniator on for ten second the shuts off. Make sure you have the right switches etc. Let me know, then we can brain storm on this matter. stewbison

8x25 minolta compact bionoculars center focus knob will not turn. Have taken screw off center knob and removed 4 rubber strips on bionocular body and looks like allen? screw underneath. No obvious way...


They don't make these things easy to take apart, or fix. Here's your best shot- take it into a camera repair shop, and see what they say. Some tech might know what you have to do to get it apart, or if it can come apart without damage or special tools.
Unfortunately, only the repair techs know how, and there aren't too many (if any) of them, since they often just charge a set amount and send a refurbished or new pair to the customer.
Wish I had a more specific answer, but good luck to you, and with just a bit, you'll figure this out.

I see 2 planes of vision on my 8x24 weaver binocular


Hi,

This is more common than you would think.. Here's how to set up a pair of binoculars to suit yourself.
Any good binocular will be able to do this and the reason is to allow you to adjust them for the difference in strenght between your two eyes. I wear glasses myself and sometimes contact lenses so it's good to be able to quickly adjust them.

1. turn the binoculars over so you are looking at the underside.
2. on the eyepieces can you see on one eye(usually the right eye) a little plus - minus marking. The eyepiece should be able to rotate a little to each side of this marking.
3. Set the rotating eyepiece to the middle setting.
4. Look through the binoculars as normal and bring the two sides together until you form the two circles that you see into one.
5. Pick an object app 10 meters away.
6 Presuming that the adjustable eyepiece is on the right hand side then close your right eye, look at the middle distance object you chose with your left eye and use the central focusing knob/wheel in the middle to bring your left eyepiece into focus.
7. Now, close your left eye and adjust the rotating right hand eyepiece while looking at the same object until your right eyepiece is in focus.
8. The binoculars should now be set for the differences in strenght of your eyes and you can use the middle focus control as normal.

Most binoculars have a soft rubber eyepiece that can be folded back for people who wear glasses but I, like most people I know who wear glasses, find it horribly uncomfortable.

This method allows you to set them for yourself and if someone else uses your binoculars you can quickly reset them for you.

Hope this helps...


- Oh yeah, sorry, forgot to mention.. This set up is so you can use them without wearing your glasses.. Much more comfortable!!

Hitachi 53UWX10BA dynamic convergence works but blue is blurry


I know this set very well---you are saying convergence adjusts ok everywhere? If you understand that the blue is usually de-focused a little----there are only two ways to adjust the focus of each tube-----

1.) Behind the front speaker grill there is an inspection plate---with it removed you will see a small black plastic block with 6 controls on it; it is the MASTER SCREEN/ FOCUS BLOCK

2.) THREE of the controls left to right are Screen controls(red, green and blue) and the other 3 are FOCUS--IT IS ALL black and you need to look close to identify which is focus and which is screen---you are looking for the BLUE focus control(one of the 6)

3.) With the convergence grid on screen cover the RED and GREEN lens in the set and try to adjust the focus of the blue(I presume you know how to put the set into the Convergence mode?

4.) The only other way to adjust the Blue focus is from the back of the set---with the Red and Green lens covered up place a blanket over the top of the set that covers the whole screen--from the back of the set you will note that all three of the black focal lens have a wing nut---with the convergence grid up and only blue lines present(Green and Red lens covered with a cloth) look from behind the set at the grid---loosen the wing nut on the blue lens and slowly slide the lens left or right until the blue has the best focus possible----if it will not adjust with the focal lens or the front focus control you have a circuit problem.

I do this here for free and if this information helps you take a minute and give me a vote here. If you have any questions or need advice reply to this posting here and I will assist you.

Need to replace large lens cover for Swarovski binocular 10x42


Try Adorama camera in New York. They are good to deal with. Binoculars.com also used to carry parts but I have found since they sold to a conglomerate their customer service is wanting and i switched to Adorama. They also post international.
