I've got a pair of SLC 10x42 binocs I've been really pleased with over the years. Hearing great things on the NL Pure line and am looking at the 10x42s. Any thoughts on if they're really worth the price to upgrade and that much better than the SLCs in the field?
 
I made the swap from SLC to NL last year. It’s not just the clarity, it’s the FOV. If you are someone who spends lots of time behind a tripod, NLs are ridiculous.

They are that much better than the SLCs, but not that much better than ELs. You can find the ELs new for $1800 with some searching.
Have you done an extensive side by side comparison of the EL vs SLCs in field conditions and low light? The reason I ask is that my understanding of the difference between the two models is the ‘Swaro vision’ flattening with the ELs. Reading the specs, the SLCs actually have 91% light transmission vs 90% for the ELs.

Yes, had all three models. You aren’t going to notice a difference in 1% light transmission. What you are going to notice is a much more usable field of view and sharper image. The jump from SLC to EL is huge. EL to NL is slight, basically FOV, little less weight, and more ergonomic for some. Where the NL makes the most sense is in the 12x (what I currently use)

Great insight, thank you! Can you elaborate some on what you mean by your statement with "12x"? I've always been a 10x42 guy. What are the benefits and drawbacks between the two (10x vs 12x)?
 
I've had the SLC's and both 10x, 12x NL's. No doubt the NL's are top of the chain, SLC's are no slouch. I started with the 10x42 SCL's, I liked them a lot. I got a wild hair and a few extra bucks. Went out and bought the 12x42 NL's, they're awesome off a tripod. Not so much for me as I wanted to use them freehanded sometimes. I traded them off for 10x42 NL's, still using them and very happy. To be fair I have 15x56 SLC's that I love on the tripod. Gave the 10x42 SLC's to my son.

Because of the increase of FOV in the NL line, the 12x has the same FOV as most other 10x. Something about the increased FOV makes it easier to hand hold for some when compared to other 12x binoculars.
Don’t get me wrong, it’s still not as steady as 10x and 10x is probably the best choice for all around general use. I went 12x because I was carrying 10x on chest and 15x in pack for several hunts a year, the 12x is a compromise to drop 3lbs from my pack.
 
Thank you, that insight from experience is so much more helpful that I can get just by perusing and comparing specs etc or looking thru at the store. Seems one can't go wrong with Swaros (as it should be w price). Just shopping for now but probably gonna make a decision soon. 'ppreciate ya
 
I’ll echo what others have said; I’ve had slc’s for a decade or so and spent a little time with a friends nl’s this winter. The only real difference I noticed was the field of view. They may have been a little brighter but it didn’t blow my mind. I was actually a little surprised how well my slc’s compared. I’ll also add my outdoorsmans bino adapter system was way, way better than the swaro one my friend has that fell apart multiple times until we finally lost a couple pieces and couldn’t repair it
