Have a look thru some ZEISS Conquest HD's man. New they're $1000.00 and used you can get'em like $750-ish. Looking thru 'em is like crack for your brain! Your brain loves that it is then now getting all this image data even sharper and brighter than your own eyes can do for you! (Especially after some years on ya makes your vision degrade over time. You don't even realize to what degree until you look thru some good glass!Another thought, if you check here again before calling Doug at camera land.
What binoculars are you carrying? I'm a proponent and advise spending more on binoculars and get a good scope. Not saying you shouldn't upgrade from what you've listed in your original post. A hunter should be using binoculars exponentially more than the scope most cases where a shot up to 300 yards could occur as shared in your opening post.
This season, Viper 12x50s picked out that deer on the hillside in my post above in very low light and the VX3HD 3.5-10x40 did a better job at 10 power than the Vipers. Previously had a VX-2 on that gun. The Vipers were comparable to that but the new HD Leupold is nicer glass to my eye.
Doing the math the exit pupils were virtually identical so I chalk that up to better HD glass in the Leupold scope.
My next purchase is not a better scope however it will be stepping up in binocular glass.
As a tangent, IMO Viper HD's are good binoculars for the price (when I got them) however I'm starting to think I may want to cry once and buy once with my next binoculars despite being stubborn thinking that $500 is a lot (approx Viper cost). I may not be crying for a $2,000 pair of binoculars but an upgrade from the Vipers still will bring a tear to my eye.
