Saw a thing on a news site about the 10 best binoculars for hunting. It was interesting, but WTF?
I have had a bino in my hand every day for decades. There is no "best".
Any bino is better than no bino, much better. One cannot really do much bird watching without one.
One place to start might be to decide how much you are willing to spend. There are very good binos in many price ranges. The truth is that today a "cheap" bino might excel beyond what one costing much more would have ten years back. To that end, don't over look store brands.
The place to begin is to go to a store and look through as many as possible. Have some fun, then come home and search the web for the best price.
A bino good for one is not as good for another person. We have different needs, different hands, different opinions. I have a few pair, and all are quite different in size and price. I use them all, can't think of one I could give away -- in fact would like to have more. I have a pair handy in every room, keep a pair out here on the porch, and of course in my Jeep. If you don't have a pair, your first pair should fit many situations. Figure out what that is to buy the "best" for you.
The ones I use on the porch are excellent, but I prefer a much smaller pair when walking in the woods. I use a different pair when on my boat.
Here is the deal:
- weight can be important. A pair too heavy will not be fun. I am a big guy, but prefer small when on the move. Here on the porch, use a heavier pair as I am seated and can brace my elbows against my body. A small "quality" 10X32 can be amazing. My porch pair is 12X50 and just shames the view coming from my high end HD television.
- way back when waterproof and rugged was good, but now most of them are that. I like a rubber coating, but that is not a deal breaker. They should feel good in your hands, and today most are designed with that goal. Handle them. Don't buy what does not please as to feel.
- focus range is important. All focus to ~, but I am talking how close they will focus. Closer focus generally runs the price up some. A bino can also be a sort of microscope for looking at butterflys on a flower or a bird who has landed on your foot. I would say go for at least ten foot. My porch pair do only that, and it is a trade off for the 50 foot view, but I would prefer 5 ft.
- power is what many look at first, but maybe should not. Binos are marked 'powerXobjective lens size' (8x32, 10X42, etc). The first number deals most with magnification and the second with ability to gather light. A larger objective lens lets in more light. The truth is the quality of the lens is the important thing as to power and light gathering.
Most 'experts' say birders should go 8 power. That is because the higher the power, the harder to hold still for a good view. Mine are all 10 or 12 power and I have no problem.
- quality lens is the deal for bird watching. The goal is to look at the bird and see detail. You must give to get. To that end, figure what the bino will be needed for most (close up, far away, low light, portability, etc). The biggest difference in the view you get from a bino is the quality of the lens. Like in all areas of life, there is a breaking point where you pay a lot more for smaller and smaller increments of improvement.
So what should you by?
Decide what you will use them for, then go to a store and play with all the ones in that category. A safe way if that option is not available to you is to go with the major brands. I find binos are one item where ebay does not work as well. I like to buy used crap, but most people with an excellent bino do not sell them, even when they upgrade. Still you might find a deal there from an estate sale. My first pair was $20 from a pawn shop, and I was hooked. My last pair cost - "ha ha" not going there as my Bride might read this.
A good place to shop is Eagle Optics
The service from these guys is unmatched. Their house brand "Ranger" is a best buy.
The important thing is to get your self some binos so you can see the birds.
