You guys likely will laugh at me, but for BACKPACKING I use a soviet made Yukon 20-50 x 50 I got on ebay for $50 bucks. I figured what the heck if it's trash, I'll eat the $50 bucks and buy somthing better, that was 4 years ago. It's a 50mm variable range scope. I have used it for four years now, and it works well because it's handy and it's light and it's easy to use, and it's clear.
I cant say it's the best compact, it likly is not, but I've not used them all, so I cant say. However, I do know good optics and good glass and there is a purpose for everything. I do not skimp on my optics and most of you can attenst that I'm the guy always tell you to spend more money, as much as you can, on glass.
Well this time is different. This little, light weight scope fits the bill for me, and like I said, I'm a little picky when it comes to good glass.
I'd say for the $50 bucks I spent on it, its been a great investiment. and If i ever break it, or lose it, so what, I'll buy another one. so far, it's worked great, and at the end of the day, it's as good as my other, more expensive scopes because I take it with me, and I use it, and I treat it like it's a cheap scope - or better yet, like the tool it is! If I go trough one every 5 years, that's only 200 bucks in the rest of my hard core hunting life!
Keep in mind, I'm not using it to glass all day for deer, I'm using it to get a better, closer and more accurate reading of the animals I've spotted with my glasses. I would not use it for glassing all day long, but that said, it's BETTER than any of the cheaper models out there that you cant glass all day long throught either, even the other compacts like the burris, and the nikons, and the cabelas, and the taskos, and the leupolds are not made to stare through all day long.
Still, I'd buy it again. Got it on ebay, it's called the Yukon and it's the 50mm Yukon, made it russia, I believe. I saw one on there recently for a buy it now price of $50 bucks. I'd say unless you plan to make it your primary scope, it's a good bet. PS, Ive never had it fog up either.
