Just one. Set at 25-yards.

For hunting, I won't take a shot past 35 yards or so, and with one pin, I can keep it on the kill-zone from 10 to 35 and still hit it, a little lower at closer distances and a little higher at farther diastances. I like it because it saves me someconfusion at the moment of truth.

Now, for target, I've got a nice 5-pin sight.
