I have had this about a year and use it to spot hits on steel targets at the 1K range. It did that job nicely. I would not say this is going to pick up detail on a rack that your chasing. Theattached pics are using my Samsung s9 and a phone scope adapter. The first is showing from 300 to 1000 yard targets on 20x. The next is showing 900 & 1000k zoomed in probably on 40x.
