I think you will find them very difficult to use without a support - not many (actually, not any) people I know can hand hold much past 10 power, and then thoroughly study the details in the view. It helps a bit to grasp over the beak of your ball cap, on top of those binos, to steady them. You will notice the difficulty, for example, trying to pick out a deer's hind leg, or a coyote's face in a stand of poplar trees a 1,000 yards away - have to really bear down and pick the scene apart to find that shape, and much much harder to do with the image shaking from your grip. Quality of glass (image detail) becomes more important than magnification - my brother regularly can count points on elk with his 10x Leica's that his buddies with more powerful spotting scopes can not.
