Now from everything I've read the Nikon ED50 is kind of the benchmark when it comes to a compact backcountry spotter. What other compact spotters are out there that offer good optical quality in a small light weight package. Now I know these type of spotters aren't going to be on the same level of optical quality like a full size Swaro or Leica but can still get the job done on a high country mule deer hunt. So what other spotters should I take a look at?
