Hi Guys, new guy here to the forum. Looking for advice on some rf binoculars, i am going from Viper hd's to possibly a used set of Swarovski EL Range non TA or the Leica Geovid R. I dont need the ballistic stuff so looking at my basic options for under or close to $2000, How big of an improvement is the Swaro glass over the Leica or is there much difference? Any other options out there i should look at?
