This kind of problem is always in the gray, since, chances are, one side has been "sprung" out of position. Sometimes one can temporarily flex it back to normal, but once mechanical (metal and plastic) parts are stressed, they tend to revert back to the bad position. It's also hard to tell which way to rebend the housing to reset it to it's original position, and often the problem is made worse by even trying, or exerting too much force. I had an older set that I would always have to twist and torque to sync the images, and just lived with it. Another thing to consider is that trying to twist it back might compromise the waterproof integrity of the unit. It's a nice set of binoculars, so I would recommend having a repair facility fix it, unless they want too much. Not sure I helped out, but good luck getting it fixed!

The binoculars need collimation. The two sides are supposed to be parallel, if they are not you see two heads on horses, two footballs, two baseball bats etc. Check the binoculars for any external signs of damage. Are the front housings sitting properly in the body, is one of them not straight? If there is no obvious signs then you will need to take them to someone who can rebuild them for you. Usually the place where you bought them should be able to help you with a repair centre.

Is my bushnell insta vision 7x35 or 10x50- how do I tell ?


The first number is the magnification the second number is the size in millimeters of the objective (large lens) So if you measure the diameter of the front large lens that will give you the size. So a 10x50 means a magnifyng power of 10 and an objective of 50mm.
Now to find out the magnification if you don't know what it is. Measure the front lens. Then if you look through the eyepiece lens while holding it away from you you will see that there is in each a small circle of light. That it what is known as the exit pupil. It lines up with the pupil of your eyes when you have the binoculars pressed up against your eyes. Now measure the diameter of the exit pupil in millimeters. It will only be a small number.

To work out the magnification use this formula. Magnification = Objective size divided by the exit pupil.
So a 10x50 will look like this M = 50 divided by 5....therefore M =10 which is the magnification.

Both the 7x35 and 10x50 will have an exit pupil of 5mm. So if yours is one of these then all you need is the objective (large) lens size.

Double vision


The distance between the centers of the eyepieces of your binocular must be the same as the distance between your pupils. This distance is adjusted as follows: 1. Focus on a distant object. 2. Pivot the two halves of your binocular farther or closer apart until you can see a single unobstructed, circular field of view. Make sure to focus on a distant object when you do this because when you focus on a close object you always see two slightly overlapping circular fields. Your binocular may have a scale on the top, between the eyepieces, to help you remember this setting.
