Binoculars are very expensive and can be hard to maintain. If you want to keep your binoculars in mint condition, you need to take steps to prevent damage from happening in the first place. One way to prevent this is by purchasing a binocular repair kit. Whether you decide to try your hand at the repairs yourself or to have them done by a third party, it is important to get your binoculars back to working order.
A good place to start is with the focusing knob. One of the most basic components in binoculars, the focusing knob allows you to adjust the distance of the eyepieces. This can help improve your zooming capabilities and the overall performance of your binoculars. You can use a small flat-bladed screwdriver to unscrew the focusing knob.
It isn't uncommon for a lens to shift out of its proper position when you accidentally drop it. This is the most common reason for a binocular malfunction, and is often a simple fix. If you notice your lenses are no longer focusing, consider cleaning them. They may be cleaned with a microfiber cloth or with a soap and water solution. Be sure to allow them to dry out completely before reassembling.
The prisms are the most complicated part of your binoculars. While it isn't impossible to repair them, a collimator might be the best route. There are two types of prisms: fixed and adjustable. Adjusting the fixed type might be a bit of a pain, but adjusting the adjustable version shouldn't be difficult. To align the prisms to their optimal position, you can either use a small screwdriver to nudge the prisms a bit or a more upscale binocular collimator.
Other notable components of your binoculars include the diopter adjustment pin and the focusing device. These can be tricky to clean, so it's a good idea to keep a few cleaning cloths around. In addition to the aforementioned, a cleaning solution in the form of compressed air is another way to make sure your binoculars are sparkling clean. Use the aforementioned to blow out dirt, smudges, and debris that has accumulated in the ocular lenses over the years.
One of the most impressive things about binoculars is their versatility. You can adjust the lens and focusing knobs, as well as adjust the tilt of the prisms. Regardless of your skillset, repairing a pair of binoculars can be a fun and rewarding experience. But if you're not up for the task, don't worry: most manufacturers provide a binocular repair manual, which includes instructions on how to perform such a feat.
For more specialized repairs, consider the services of a binocular repair shop. This can be the cheapest and easiest way to have your binoculars in tip-top shape, so it is a worthwhile investment. Many companies offer their own binocular repair kits, which should include quality tools for the job.
Before attempting any of these tasks, however, be sure to check your binoculars for any signs of warranty expiration. You can also check with the manufacturer to see if there are any specific maintenance requirements for your model. Some companies even offer optional treatments to ensure your binoculars will work in the harshest of climates.
