Arrow I found the truth!

After searching a lot now I do not have enough money to buy a good pair of Roof binoculars with "phase coating" + "Nitrogen seal". So, in my limit of investment I decided to cancell one these features. As I live near the beach, so the "Nitrogen seal" is more important to me than the "phase coating".

Finally, I need suggestions of good Roof binoculars 8x42 with "Nitrogen seal", but without "phase coating.

Please help me, my friend will travel to New York in three days, and I have to prepare a list of models/prices.

Thanks a lot.

I can't think of a binocular these days without nitrogen or some other type gas to serve the same purpose. Phase coating is becoming pretty much standard on any decent roof prism bino. Perhaps you could suggest a price point and we could go from there. Wecome aboard.

I can spend $150 to $200 (and no more).
I found this models:

Nikon Trailblazer 8x42
Bushnell Trophy 8x42
Celestron Outland LX 8x42

Are they ok to me?

thanks a lot, my friends.

In that price range, why not go for a porro prism binocular?

Pentax PCF-WP 8x40, Nikon Action Extreme 8x40, Bushnell Legend 8x42, Leupold Mesa 8x42, Sightron S2 8x42

These would give you equal or better view than just about any roof prism binocular under $300.

Thanks, I know that these Porros are very good, but I preffer Roof because people says that needs little repair and are more resistant.

Modern porro binoculars from reputable makers are quite durable and well built.  Ultimately, I doubt you will find under $200 roof binoculars to be any more durable than under $200 porro binoculars.

Ah, it will be my first binocular. Is it difficult to colimate Porros (with nitrogen) like "Nikon action ex" or "Pentax PFCII"? I talked about durability and strength because I´m looking a binocular that needs little maintenance.

A modern porro from Koshkins list is pretty durable.  Unless you anticipate lots of use in extreme conditions, you should have little problem, and a binocular with a better view.
 
You are surely better off with one of those porros than a non phase corrected roof.
 
Collimation refers to proper alignment of the two sides of the binocular.  It has nothing to do with purging with nitrogen, which is a method to drive out water vapor and replace the interior contents with an inert gas that will not fog or condense inside the binocular.

Steve, Thanks.
I saw many sites that teach how to collimate porro binoculars (regulating a screw...).
But my question is if I can do it (by myself) in a porro binocular with "nitrogen seal"? Is it the same method as a porro without nitrogen?

Collimation is best left to be done by somebody who knows what they are doing.  I would not try it myself.
 
Mis collimation is usually not a problem in a new binocular.  If you treat your equipment with some care, I wouldn't worry much.  All you can do is take some reasonable care.
 
SOunds like Brazil is not a real friendly place to go binocular shopping.  Maybe you ought to save up and get two, so if one has to go off for repair, you have a spare.

For some reason, I think we might be confusing terms here. When you are saying "collimate" what exactly do you think that means? Adjusting the distance between the eye pieces? I'm having a difficult time trying to understand what the connection is with collimate and nitrogen sealed as you are stating.

Um brasileiro aqui!
Cara, esqueça sobre colimação. Isso é papo de vendedor fajuto do Mercado Livre. Binóculos de nome mesmo (e não aquelas porcarias do Mercado Livre) não precisam ser colimados nunca. Aqui o pessoal sequer menciona isso!

Translating:
A brazilian guy here!
Man, forget about collimation. This is bullsh*t talk from seller of Mercado Livre (brazilian ebay). Really good binoculars (and not those sh*ts on Mercado Livre) dont need to be collimated, never. Here the guys dont even talk about it..

I don't even know what he was talking about, but seeing he is from a different zip code, I was trying to understand what he was asking. Sounds like perhaps you might know what he was trying to say as you guys might be familiar with the terms he was using that could be different than how we would use those terms. I didn't get it.

Seriously, if you dont have money, take a Porro Prism.
Its better to pay the same value but for better quality.

What about Leupold 10x50 Mesa?

If you insist, I would chose Swift but ... they are not that good... (this model)
