I have a pulsar xq38, 2.2-8.8 digital zoom, it's been problem free for me for 3 years. Depending on cover and ambient temperatures I can positively distinguish between canines and deer out beyond 600 yards- but part of that is in how the animal is moving. I've also looked at critters in the brush at much closer ranges and been unable to distinguish what I'm looking at due to the obstructions preventing me from seeing the overall shape. Mine doesn't have internal recording capabilities and I use an external battery pack. The digital zoom is pretty worthless in my opinion due to the pixelation mentioned by others. I keep mine on 2.2 but do like the picture in picture mode for aiming, keeping it at low zoom gives a better FOV anyway.
Range estimation is difficult as it does not have range finding capabilities. It excels at shooting within a couple hundred yards. My furthest coyote kill was about 440 yards with it. I knew it was a ways out, missed first shot coyote just stood there so I held higher and got it. It was a moonlit night so I ranged trees I had been near when shooting after I located the coyote hence the about 440. It is great hunting over a bait or smaller openings where you are shooting at known ranges.
If you don't have a separate scanner I would recommend a good tripod when using it hunting as it quickly gets heavy when looking around with it.
