They claim gen 2+ but I'm guessing that's with the IR lighting things up and the pretty good resolution of the little B&W screen. A true gen 2 scope would be that bright withOUT the IR source. Either way, it's SOoooo much better than the old gen 1 tube scope, IR or not. It's actually usable as you can see something besides vague silhouettes shimmering in a distorted green circle. What I've never liked about the tube type scopes is the "swimming" the image does as you pan around, and the fuzzy edges that you can never get focused. There's none of that crap with the digital scope. If the object is not lit well enough with IR, then there's a little "TV snow" but even that beats out the tube scope's images.
I got mine from eBay from what turned out to be a pawn shop in Ohio. The original box has a price tag from Norton's Sports with $599.95. I paid 'only' $269 for mine, and it's used, but in nice condition. Most of those (Bushnell Stealth) and a similar Yukon Ranger are on average $350 ~ $375 on eBay. For what it does, I think it's worth the price. It wasn't worth the $$$ for the old tube scopes.
You do have to watch out for the rip-off artists though, as some are as high as $800. Or... something like $325 and $70 shipping. The high S&H has always annoyed the heck out of me, because it's just a profit-padding device sellers use to bypass eBay and Paypal seller's fees. (The final sale fees do not include S&H charges) You see lots of point and click cameras that you know weigh 5 oz. with $35 shipping, and that's why - they're not padding the packing box with lead bricks, they're padding their wallets with your dough.
