When you get to the SLC series, the jump between grades gets way smaller. I have looked at the same deer in South Texas through my SLC's and the rancher's EL's, and he got maybe a minute more visibility in the treeline than I had. If I had not already known where the deer was, I might not have been able to find him.

He did have an older pair of Zeiss 15 x 56mm that were unreal, but not very handy. Weighed more than double my Swarovski's.

Kowa also has some good glass. That's the spotting scope I have, cause I don't want to have $4K in an item I only use occasionally.

That being said, if I was moving out west, a Swarovski spotting scope or their giant binoculars would be my first purchase.

The only binoculars that I have ever tried better than my Swarovski SLC's were also made by Swarovski. EL better than SLC, and based on what Wes said above, NL must be better than the EL.

My buddy grabbed the EL's and looked thru my SLCs side by side. The only difference is in the edge of the glass

My understanding is that light transmission is capped at 8x. So for example a pair of Swarovski 7x42 give you 6x, 10x50 gives you 5x, etc… This is why the old straight 8 scope is the best light gathering scope you can buy, but you lose the ability to “zoom in”. All depends on what you want. I personally have multiple pairs of the 7x42 for myself and my family because they are good on a large food plot, but also good hunting the woods.

The maximum exit pupil and Young human eye will dilate is 7mm. Divide a 8X56mm binocular and this is the maximum a Young human eye will maximize any binocular for low light capabilities. It is more to it than this though. Build quality and lens quality, prizm quality, and lens coatings quality plus more other factors has alot to do with binocular low light capabilities.

I've had cheap binocs, mid range binocs, marine (Steiner 10x50's, love them duck hunting when they can be sitting on a shelf, hate them around my neck), and now am running 8x42 Swaro, SLC I bought used on here a few months ago. Oh my goodness, these have worked this year while hunting a field, from a tree stand, walking old logging roads, and up at the lake just looking. I'm not even going to consider anything else unless I decide to start hunting something out West and need more magnification, then may think of a light spotter and still take my 8x binos. I was worried about the 8x, never had a pair, I always ran 10x, man in Alabama unless you are hunting over soy bean fields in Choctaw and Marengo Counties, 8x is the way to go for me and my eyes. These thing pop at dawn and dusk. I have had a lot of time to compare all of what I have side by side in the morning at evening up at the lake, wife either still asleep or working on computer and I had alone time, I was worried I spent money unnecessarily, I didn't. Nothing I have Leupold 10x50, Steiner 10x50, Swift 10x42, Snypex 10x42 (a freebe with Steiners from B&H), and a Zeiss Victory rangefinder monocular 8x, comes close to these. I did have a friend come by the house at the lake with his Vortex Razor Hd 10x42's, looking up and down our slough, it wasn't even close until well after sunup. The range across my slough is 110-150 yards depending on where I'm looking, sitting comfortably in chairs, I could have seen deer a good 20 minutes counting points before he could. Now, I only had about 12-15 minutes just seeing a blob, like a big log or stump. His Razors were about like my Steiners. The proof was in the fine details. The swaros had the details. I couldn't be happier with the SLC's at a huge discounted price of buying used. When looking out of the slough toward Smith Mountain, the 10x just couldn't outperform the swaros even at extended range the way I thought they would. Now I'll say, my eyes are not the best, I'm not legally blind, but I'm not 20/20 either. My extended range vision isn't where I would like it. I can see the difference in quality glass, some have such great eyes they can't. My older friend sure could.

Others I considered, Swaro EL 10x42, Zeiss SFL 10x40 for their size and weight (I had wished I could have laid my hands on those and tried them until I actually saw what 8x can do in my hunting style, I'm glad I didn't), Zeiss Conquest 10x42 (what a huge discounted price right now - yeah some mention the eyecups, just order the extended ones from Zeiss for free and get the 8x ones). Would I want the Swaro Pure, the Zeiss Victory SFT, yeah, but those are way out of my price range. I did about like what Big Game Hunter mentioned, decided what I would spend and added 50%, $1500. I found a pair of EL on B&H for 1449, tax pushed it above my limit 10x42 used, I'm so glad I went with the 8x for my hunting purposes. On most of our greenfields, I only slightly have to move my head to see the entire greenfield at dawn or dusk with the 8x (now I have to move more to see up into the tree lines), with the 10x it was huge swings from left to right. Now, how did I decide to use the 8x, I went to a store and was allowed to walk outside with some Vortex 8x, 10x and compare to my Steiners, the 8x's weighed less (I kept them around my neck to feel the weight difference), and gave me so much more viewing area. I just took a chance by doing research on multiple web sights, reading different forums, and viewing at a store (yeah, it wasn't at dawn or dusk, but I could tell the viewing area and looking in shadows).

I like the Swaro quality and warranty reading on different forums (and owning several riflescopes), I like my Zeiss quality (owned a Diavari riflescope for around 24 years, still amazing glass) (warranty after the 10 years of use is hit or miss some say, I've never needed it). The Leica warranty is hit or miss more misses from what I've read. The Vortex warranty is great, but people have to use it too often and are missing hunting time, nope not for me. I have a Meopta scope on my AR, great glass, not in my swaro scopes or Zeiss scope glass class, then again its' less than half the new price too. The Nikons have one set of binoculars the birders like, its a 7X, I considered buying it, but those are birders, not dawn and dusk any weather hunters.

I've typed a bunch so you can see what I've been through, gone through, etc. The buy once/cry once crowd is right on one hand, but sometimes you just don't have that kind of money to cry once. Sometimes you build up to it. My first car wasn't a Vette, but in time I owned one. My first truck wasn't the same truck I have now, but the truck I have now has lasted 27 years and counting. Unless you just need the glass right now, save a little at a time and buy what will fill the bill. Decide where you're at as a hunter and where your wallet is, and buy from there.
