Binocular magnification

Sitting on the fence about a new pair of binos for a while now. Still not sure, but thought I would ask for opinions....

I have used a 10x bino for many years (Minox), but have always found they are just a little too much to hold steady - particularly when walking/hiking and trying to hold them freehand. It's not bad, but just not as steady as I would like.

I have considered 8x but, when I made the 10x choice many years ago, found 8x to be not quite enough magnification - or at least felt that way at the time. Wanted to be able to count those tines, or really look into that far off timber and 10x seemed to be a little better. Being propped up by sitting down, or against a tree, with 10x gives a steady image but there is a tradeoff with a less sharp image when not braced.

The set I had prior was a 9x Leupold. A decent set at the time, but certainly not great quality glass. Always thought that 9x was a good 'compromise' - I can hold fairly steady when not braced and has just that little bit of extra magnification over the 8x that I liked. To be fair, I haven't owned an 8x (except a compact pair that my wife uses on occasion), so that is an opinion without much real world testing. But, in the little I have used all different magnifications, I think the 9x might be a very good option.

I use my binoculars often and anywhere from wide open prairies, across mountain valleys to the thick timber of the northern Whitetail woods. Still thinking that 8x is not enough, but 10X is too much, but 9x is hard to find. The Maven 9x's seem interesting, but the size looks a little big. Aside from those, doesn't seem to be many others that make a 9x. Hoping for some opinions to help me make a choice of what could be best.

I hear great things about those Maven 9x45s. Good option to check out or demo at least.

I've never had a problem holding 10x steady and like the increased magnification for the wide open West. It's my favorite. I value that magnification over the main benefit that I understand from the 8x--larger field of view.

My go to pair for a few years now had been the swaro cl 10x30. They’re incredibly light and easy to hand hold without shaking. Great quality glass for the money. I sold off my slc 10x42 in preference of these. With the new model out lots can be found at a pretty good discount too.

Maven 9x sounds like it will fit the bill. Personally i find a slightly heavier bino easier to steady.

Those really must be something! I have some 8x30 SLC, and while they are better than most everything I've tried them against, the current 10x42 SLC was a lot better. I need to look into the CL.

Don’t get me wrong. The SLCs are definitely better. But for the weight savings I only lose about 7 minutes of daylight on dawn/dusk. Was definitely worth it to me

Thanks for the different recommendations.
I likely wasn't very clear in the original post - at this point I am more interested in the magnification question than the specific model. 8, 9 or 10X? Which would you choose?

Ive bounce back and fourth a few different times. I tend to like 8x better for the following reasons:

1. Wider FOV. In the SLC platform you are looking at almost +80 feet more with the 8x. On cheaper glass this might mean a larger sweet spot.
2. 8x handheld seems a little clearer to me. Much easier to handhold. Image can get a little distorted with bouncing around. I dont know about you but when i am running and gunning and then need to throw the glass up, it can be an ugly sight picture.
3. When i compared 8x vs 10x magnification side by side, i could barely tell at difference at 100-200 yards. There was a difference but not as much as you'd think.
4. Exit pupil is larger on 8x.

It's not the only glass i take though.

What does the larger exit pupal do? Honestly curious. This may be related be how much better is light gathering on the 8x versus the 10x?

Magnification should be compared at a mile or two to get the benefit of the 10x. People use it to see those farther open distances.

Yes basically the light gathering. Even with that though i wonder how much it really makes a difference. I had an 8x42 slc hd and 10x42 el sv, and to my eye they both appeared equally bright. Maybe the slc was slightly brighter but im not 100% on that. I also tested them both until the "lights" went out and they both tapped out at the same time.

I do get what you are saying at longer distances but at that range I'm pulling out a spotter.

At 2000 yards a 10x is going to appear like it is at 200 yards. An 8x is going to appear like it's at 250 yards at the same distance.

If you are only able to take one glass out west then yeah I'm going 10x+.

Binos are good up to 2 miles for sure, at least the 10x for big animals like elk. I definitely agree on pairing an 8 or 10x with a spotter. Deadly combo. The guys who run the smaller bino with a 15x have a decent idea too.

I found I'm fairly similar to the OP. I know it's not the case for everyone, but I tend to have a difficult time holding 10x binos as steady as I want free hand. It's not bad if I'm sitting in a steady position but if I'm standing to take a quick look while on the move it isn't ideal for me. I went with the Maven B.2's in 9 power and I've been very happy with them. Their one downside is they are bigger and heavier than many 10x models out there. They feel great in the hands but they take a larger bino harness and add a few ounces over other models. The field of view, brightness and clarity are worth the weight/size to me, especially at their price point. If I had the money I'd go with the Swaro EL 8.5x42's as I think they check every box for what I want/need in a bino. I'm happy enough with the Mavens that I'd rather spend the money on other things.

No question about it the extra magnification of a 10x can make a difference at longer distances (especially on a tripod), but for my uses a quality 8 or 9 power will have the clarity to see what I need to see (at least for how I hunt). The extra field of view has become much more important to me than the slight loss in magnification. At least that's my take on it. I don't claim to be an optics expert and hunting different areas or using different hunting styles might lead to a different opinion. In the end the only way to know what you prefer is to try a few options out and decide what is most important to you as there are always tradeoffs to consider.

Same for me.^^^^^^^
8x better for quick one-hand glance during a stalk or treestand hunting with bow in hand
8x better/wider depth of field which is very helpful when looking at a group of animals or in thick cover.
Any viewing limitation I've had with 8x would have been better resolved with a spotter (I've never used 15x so no opinion there)

When glassing distances start exceeding one mile I would prefer a spotter to make detailed animal decisions over any binoculars.
