In general, the closer to the hinge you put the rest, the better. However, for minute of deer accuracy, it really doesn't make that much difference. I always have to rest mine on something. In my walking days, I used the fore stated walking stick method, or a fence post, tree, or whatever I could find. Now days I'm mostly in my tree stand w/ shooting rail.
PS If you're shooting a pistol scope for the first time, it will take some getting used to.
