Man, you don't need anything too fancy, they are handy to have but knowing your equipment is a main focus IMO. With that being said, I still have the first one I ever bought and I think it is the first one that bushnell come out with, it is bigger than my 10X42 bino's and it gets the job done. If I were to be stalking I would upgrade to a smaller pair butmine get the job done in a still hunting situation....I don't get to do too much stalking other than some hogs....
