Depends on which specific Cabela's scope you're talking about.
They have a few different lines under their brand name. The lower cost models, I have no clue. The "Euro" optics under the Cabela's name (bino's, spotters, and rifle scopes) are made by Meopta.
I own Meopta binos and they're superb.
I also own a Cabela's Euro riflescope, a 3-9x42. I got it just a few weeks ago, but so far, I've compared it in dim light to some well-known brands, and it easily held its own. I shot out to 200 yards with it at the range, and it doesn't leave me wanting for anything other than more user-friendly dials (they're ok, but there are better dial/turret designs out there....once it's zeroed, no big deal, but when getting a zero on the rifle, it's a little bit of a pain.)
The optics are awesome.....easily equal to (or maybe better than) a Zeiss Conquest.
Meopta makes good stuff. One needn't be shy about the integrity of a Meopta product.
If you're talking about the Alaskan Guide series, or whatever it is, I don't know who makes those optics for Cabela's.
I own a Conquest, and I've had it side by side with the Euro/Meopta. The Meopta doesn't lose a thing to the Zeiss, and I think the image is just slightly brighter for the Meopta. I've had them side by side in my back yard from sunset to flat dark, looking at them side by side at a USAF1951 target.
I don't mean to take anything from the Conquest. It's a decent scope, for sure. I really like my Conquest, and I'm sure not running out to replace it. But Meopta needs to be given their due. They make darn good optics. I have a pair of Zeiss Conquest 8x30 binos, and a pair of Meopta Meostar B1 binos in 7x42. My Zeiss stay in the truck, and I use them a lot, as they're always there when I need them.
The Meoptas are on my harness when I hunt, no if's, and's, or but's about it. They are simply superb.
Yep. Diavari's will definitely outpace the Conquest (on price, too!
There's some great stuff out there for scopes these days. The Cabela's Euro is an oustanding option if you can find one at the right price and the right time. I have some peeves with the turrets, but it doesn't do anything to detract from the use of the scope, just makes me grumble at the range that it could, and should, have been done differently.
The new lines of Meopta scopes have been improved in that regard. I have no clue when that improvement will trickle down into the Euro line, though.
