It is much harder to steady your site picture using a monocular. Less field of view. Mostly poorer optics. If your getting dizzy and can't get focus with bino's you may have one side out of adjustment. Using a scope in the field would be a mistake. Unless stabilized by being mounted on a rifle it be almost impossible to use. My advise... a moderate priced 8x40 would do you purdy good in low light and give you a good field of view. Leupold, Nikon, maybe.
