Typically you see game first with your eyes or binoculars and then reacquire it with the scope. Finding it again is more problematic the higher the magnification, your field of view shrinks. Having said that I have no too little trouble finding it again with a 12 power. *IMO it is all about practice*. It wasn't easy when I started out many years ago . Sometimes I practice finding birds in a tree with 6 power, then up the game to 12 power. I hunted for years with a fixed 6X44. I've used 12 power for some really close shots when something popped out of the brush way closer than I expected, I see no issue with a 4.5 power.
