Well, seriously, typical whitetail hunters don't need rangefinders in Mo, or really anywhere. Unless they are shooting Raven crossbows at 75yds, then you might want a rangefinder. Unless you have a very specific situation, like hunting over a big bean field where shots could stretch past 300yds, you aren't gonna need a rangefinder. All those combo units do is make a heavy pair of binos. A pair of compact 8x is all you need to make sure it's your target buck that you have watched grow up for the last 4yrs. But again, that ain't the typical Mo hunter. Between my 14x scope and 6x rangefinder, I've never seen the need to carry binos, even out West. But I'm gonna add a big ole pair of 15x to the stable eventually for long glassing sessions trying to pick out Muleys from Nevada sage brush.
