One of the most useful things to bring and prepare on your camping adventure is a pair of binoculars. You can view wildlife from a safe distance, locate people, or look for directions efficiently using these. From observing the heavenly bodies to basic survival, there have also been several binoculars that have been produced for specific purposes, making them much more useful tools to have when exploring the outdoors. Given all its uses, what can you do if your pair of binoculars get broken?

10 Steps to Repair Broken Binoculars Quickly

Thankfully, a lot of manufacturers have made repairing binoculars alignment possible for users to do on their own. Each barrel includes adjustable tilt setscrews so that you can adjust the prisms properly until the images are aligned accordingly. This usually involves some tweaking of the set screws that should eventually do the trick.

However, if you’re not sure of what to do and avoid the risk of further damaging your binoculars, your best action is to find a professional to get the job done. It is important to note that the only possible repair that you can do is fix the position of the lenses. Also, if your binoculars are broken or its lenses sustain cracks, it’s already impossible to fix them۔

1. Gather the Right Equipment

The first thing to do is to have all the essential tools you need. To repair binoculars, you need a couple of items such as screwdrivers, scales, cleaning cloth, and tissue rolls. It would be better to use binocular collimators for this, but a screwdriver would get the job done.

Along with these, you’ll also need a lens screwdriver, manual, soap solution, scale, and kitchen tissue roll to fix the lenses. Other accessories that may come in handy would be a tripod stand and a target which allows you to check the accuracy of the prisms as you repair them.

2. Check the Lens Position

You should first evaluate the position of your lenses. If they have moved away from the original spot, you need to fix them right away. Understand that the lenses are the most significant and delicate component of your binoculars, as they can make or break how you’ll be able to observe various landscapes and skylines. Once you’ve identified this, you can proceed with the repairing process.

3. Remove the Lens Screws

Some binoculars that have a rubber coating to cover the lens screws. You can use the manual to be able to mark their positions on paper. After that, use the screwdriver to open them up. Most binoculars have the lens screws located on the top of the lenses. Once you’ve removed these, you can remove the lenses as well.

4. Correct the Lens Position

Remember to clean the lenses first before fixing its position. You can use a pro-grade cleaning kit or a simple microfiber cloth to do this. But if the lens is filthy, you can wash them using a soapy solution to penetrate the dirt better. Make sure to do it gently. Once the lens is dry, you can proceed with fixing the lens position.

Measure the central position of the cups and place the lenses back at the center point. Return them and adjust the position using tweezers as returning them by hand can leave fingerprints. Check if the lenses are placed exactly where they’re supposed to be by looking through them. After tightening the screws, use the scale to measure the center of the two sides. At this point, all you need to do is to make sure that both sides are equidistant.

5. Bring It Outdoors for Collimation Checking 

An efficient way of checking the collimation of your binoculars is going outside in daylight. Use it to view a prominent structure that’s at least 100 years away and has strong horizontal lines. Then, place your binoculars on a flat surface that points to it horizontally. A tripod can be used as well to stabilize the unit while you position yourself behind the unit.

6. Check the Horizontal Collimation

Relax your eyes and identify the most distinct vertical line on your chosen structure. Gently close your eyes one at a time after every few seconds to alternate the view. Identify any movement in that vertical line every shift view you make.

There are certain slight movements that are normal. For example, you may notice that the image moves a bit to the left when the left eye is open and vice versa. However, excessive vertical movements indicate that you need to make adjustments.

7. Check the Vertical Collimation

Similar as to how you check for horizontal collimation, locate the distinct vertical line in the structure. Move your eyes slowly away slowly from your binoculars while maintaining sight of the horizontal line. Check for any disproportion in the line on each lens.

8. Adjust the Tilt Setscrews of the Prisms

Identify the setscrews of the tilt adjustment on each barrel near the eyepiece. You can use a small flat-bladed screwdriver to pry open the gap located between the prism cover and the rubber cover. Peel this back until you can see the setscrews, adjusting them appropriately using the flat-bladed screwdriver.

When adjusting the tilt setscrews of the prisms, the image moves in different directions depending on how you turn them. On the left barrel, the image goes to the right and down by turning the setscrews clockwise, while turning it counterclockwise makes the image go left and upwards. For the right barrel, it goes to the left and down when turned clockwise, and right and up when set counterclockwise.

9. Review the Images

Evaluate the images by turning the setscrews back and forth. Look how the images shift apart from one another or fuse together as you do this. You would know when to stop the moment the images merge as you see them through the barrels.

10. Fix the Focus Knob

If the focus knob is also having problems, you would need additional tools for this task such as grease, cotton buds, and a magnifying glass to assist you in removing dust from the crevices of the focus knob. Once you have these, you can begin repairing this part of your binoculars.

You would know that the focus knob is broken when you hear a sound while moving it. To fix this, open the knob which can easily be removed. Apply grease on the cotton bud and use this to clean it from the inside as this will lubricate the screws and have the knob function properly.

Conclusion

Enjoying the wild on weekend is a good way to spend time but we must be ready in any circumstances that we might face while in the wild not just talking about broken binoculars and how to fix them.The key to survival is to foresee what might happen and prepare yourself. You need to be ready and always have the proper gear and equipment to face any unexpected occurrence for your own safety.
