so I read here that anything over 10x zoom is hard to keep on target, especially on a small boat (mine is 24ft) on semi rough water ( on great lakes)<br /><br />I wanted something with more magnification then the 7X50 or 8X50 recommended, can I not use a larger magnification and zoom out like with a camcorder, or is the zoom fixed on these things and focus is adjustable?<br /><br />also, what is range finding for, should I bother getting it?<br /><br />Signed, Total Newbie
