Currently I carry a small 2.5x17.5 "russian spy" monocular, which (surprisingly for its price) has excellent optical quality and is easy to focus for both close and far ranges. But I want a similar sized monocular with larger magnification, 6x or 8x would be great. There once was the ATN GoldenEye 8x but it's no longer available. There's also the Docter 8x21, but it's way too expensive for me. So I'm looking for something of the size of these monoculars. (But not a cheap imitation of the Docter 8x21, I have one [of the Nikula brand] and it's total crap. It doesn't give any more detail than the 2.5x17.5). Is there anything like this out there? Price range - less than 30$ if possible, I can maybe stretch it to 50$ if it's good quality.
