‘How to Repair Binoculars at Home? Step by Step Guide’ (1 Viewer)

Well that’s not what I’m suggesting, but it is the title of an article that I found this morning (Bill please look away now!)

It offers a variety of advice ranging from the blatantly obvious, to the dubious, to the dangerous. And in doing so it may set a new low,
see: https://deanoptics.com/how-to-repair-binoculars-at-home/
(the hot links in the article lead to even more information of the same quality)

While it's clear that English is not the author's first language, what's astonishing is his presumption
e.g. at the end he notes:
‘This guide was to acquaint you with how to repair binoculars at home. And I am pretty much sure I have been successful in doing so.
You will not have to run to an optics store if you are seeing two objects through your binoculars when there is actually one, because now you can fix their alignment conveniently.’

. . . so what more could you ask for?


Maybe the author is a professional repairer in need of more work?

Perhaps we should start a new thread ‘Most dangerous advice about binoculars ever’?

W:eek!:W! I hope somebody can get to Bill before he sees this. Some of the tools look useful however. Having, and knowing what to do with them are different things.

When you just peruse this website and the subsection under Binoculars - (Under the peeping feature) you find

The 7 Best Binoculars for Peeping and Apartment Spying, I knew it was time to depart.

I did however get some laughs.

Really.......................

From How to Repair Binocular at Home :

"As I already said, de-collimation isn’t caused by mishandling or falling, it just happens due to excessive use and tilting away of screws with the passage of time. That is why you will have to keep checking if your pair is collimated or not."

Every day is a school day !!!!!!

Oh boy, his next project will be a text on First-Aid and will contain this sage advice:
'Broken legs aren't caused by falls or other accidents but by excessive use and incorrect walking technique causing tilting of the legs during the passage of time. That is why you will need to keep checking if your legs are broken or not'.

Could have saved me buying those nice Pelicases! Is that why some bins have rubber armour, so you can catch them when they bounce back up to you!

More advices...
“ Try to avoid getting your binoculars out when strong winds are blowing or heavy rain is falling. Like both of them, if hit directly the outer coating of your binoculars, will start scratching the outer colour coating of lenses. Once the colour coating is faded, you will have no option other than buying new ones.”

You have described the Celestron 15x70 Skymaster, they should be sold
with instructions on how to adjust the prism screws, as I think every pair ever produced
will need it. :-C

Hi Jerry,

Sadly, while probably 200,000 words—over 20 years—have been expended explaining, in detail, the crapshoot one is dealing with when buying a 15x70 Skymaster, that low price keeps reeling in those who think it’s going to be them who beats the odds. It seems people would rather get their information from today’s rain puddle than the ocean of information available through minimal research. But then, experience is the best teacher, isn’t it?:cat:

So far, in this short thread, my lamp has been rubbed 3 times. So, I will speak up; I think folks have the wrong impression of my goals in commenting.

First, a caveat. I haven’t read the Internet offering in question and see no need to do so.

I am sorry that there is not a navy-trained OM with decades of experience on every corner. Or that some people get an ego stroke by trying to emulate one. I have been taken to task for saying:

“100% of the collimation tips currently on the Internet are wrong!” So, let me clarify.

“100% of the collimation tips currently on the Internet are wrong!” Boy, I feel better, now.

Can they take a damaged binocular and make it perform adequately to excellently? Absolutely. Is That “collimation”? Absolutely not.

Even so, those who offer their advice—humbly and for the right reason—should not be discounted. And I am never upset with those who try to do the right thing for the right reason.

The largest part of binocular repair can be learned through limited experience, ingenuity, patience, and a better than average manual dexterity. Collimation and conditional alignment are a whole different matter. And it’s a realm in which just talking of it makes some people feel like Albert Schweitzer, with a Red Badge of Courage, and two Olympic gold Medals. Where I draw the line is with those who don’t know their butt from a hole in the ground but have some sort of sick need to be seen as something they are not—dragging the trusting down a rabbit hole. If you can string 3 coherent sentences and have a proclivity for bending the truth you, too, can come across as an expert on anything. Within the last week, and in only 3 short sentences, one fellow proffered 3 WRONG observations. But, he had a very large cache of posts under his belt, therefore he must be right ... right?!

I think those who honestly offer their advice should be listened to, appreciated, and supported with the others being burned at the stake. Remember, “It is the mark of an educated mind to be able to entertain a thought without accepting it.” — Aristotle. Whether they are right or wrong, time will tell. Heck, I was 17 before I knew ... EVERYTHING! :cat:

Gawsh, ‘hate it whan ma tongue goze awhl the way frew ma cheek!

Cheers and blessings,

Bill

To reset the alignment screws that have moved with use in a 15x70 Skymaster, one needs to drop the binocular from a height of 7ft onto a hard kitchen floor.

This will restore the screws to the correct position.

Repeat as necessary.
