400yds is a pretty good distance. I own a barska and I will recommend against that one for the range you are looking at. I can see 100yds with decent clarity but not much past that. What I will recommend is that you want as much eye relief as you can get. My barska has almost no eye relief and it makes it very hard to see anything without your eye pressed up against it, which moves and shakes the spotting scope. I would suggest going to a gun store that has spotting scopes and looking through all of them in all price ranges to see what you are after. My eye piece is straight which works well on a bench but I might want a tilted eye piece. I guess it depends on the height of the stand. and how you like to look through it.
