What not to do with your Binoculars – Maintenance TIPS


Of course, there is the guarantee of the manufacturer, and there is the after-sale service. But the ideal is still to avoid the problems with his binoculars!

We discuss here binoculars maintenance tips and what not to do with binoculars.

Always the same problems

 Specialized sellers who care about their customers will tell you: these are always the same problems that come back. They are only exceptionally related to defects of origin but often come from misuse. Because of this, they are only very rarely taken care of by the guarantee. Better be informed!

Problem 1: The Double View

 Despite their rubber coating, the binoculars are very sensitive to shocks and falls. Obviously, the top-of-the-range models stand up to it better, but that remains problem No. 1.

In the event of an impact caused by a fall or prolonged vibrations in the trunk of the car, for example, the internal prisms may move slightly. The result is that we get a “double view”: no way to make the images of both eyes coincide!

If the problem is pronounced, the binoculars have become unusable. If it is light, you only feel an embarrassment, like an imperfect focus, but this can cause headaches in the long run.

 This lack of parallelism, as we call it, is repairable for high-end models, but the cost can exceed $100. For an economic model, there is nothing more to do.

 So, be very careful about shocks and falls.

Problem 2: Branded Lenses

 You are careful, and you regularly clean your binoculars. But are you careful to eliminate by blowing all the dust before rubbing with a cloth? This is crucial because small quartz dust (sand) is harder than glass and can scratch it.

There are maintenance kits that contain everything you need to maintain your binoculars correctly, and they are much cheaper than replacing a branded lens.

 Therefore, the principle is simple:



As far as accidents are concerned, you will limit them by using the protective caps and carrying case of your binoculars.

Problem 3: Loss of Accessories

 The binoculars are now supplied with eyepiece and lens caps against rain and dust. These caps lose themselves quickly and, in some manufacturers, it is complicated to obtain new ones, even if it is an inexpensive accessory.

If you find them unnecessary, store them and forget them. If you use them, it’s best to attach your rain cap to the neck strap and attach your lens caps to the body of the binoculars with a point of glue.

Problem 4: Fog inside the binoculars

 If it’s not a waterproof model, it’s not impossible. Fog will disappear after a few hours if you place your binoculars in a warm, dry place.

If it is a waterproof model, the warranty may occur, but only if your binoculars show no signs of shock. In fact, a shock can cause a loss of seal at the joints, and the manufacturer will then probably refuse to apply the guarantee.

 Again, AVOID SHOCKS. It’s the enemy No. 1 of the binoculars.

Problem 5: Defective Eyecups

 The rigid adjustable eyecups of modern binoculars are a certain comfort element, especially for the wearers of spectacles, but they are relatively fragile. In case of shock, they can break, or they can jam if dust, grains of sand, etc.. are introduced into their mechanism.

A repair is only possible for price binoculars. It is, therefore, best to be precautionary with the shells and to clean regularly to avoid the accumulation of dust inside.

Problem 6: Foreign bodies in binoculars

 You look in your binoculars “upside down, ” and you observe black dots inside. This does not necessarily influence the normal use of the binoculars, and you should not worry about it unnecessarily. It may happen that a small dust settles on a prism, it is of no importance.

But if it is a pale aureole, it is probably a colony of mushrooms that signals that your binoculars are no longer watertight, and that will slowly grow. If there is no shock and your binoculars are supposed to be waterproof, intervention under warranty will be possible.

If “big objects” move in your binoculars, it is because there has been breakage due to a major shock. Shards of prisms, for example, travel. For high-end binoculars, a repair fee is possible, but it will cost several hundred dollars.

Again and again, AVOID SHOCKS.
