I have about $1200 to spend on a spotting scope. I am currently shooting rimfire out to 150 yards and .204/22-250/.223 out to 300 yards. I would like to get a spotting scope that I will not have to upgrade as i increase in caliber and shooting ability out to around 600 yards. Both of these scopes appear to be highly regarded. Is there an argument for one over the other? any input would be greatly appreciated. I bought the Konusport 80 recently. It is a serviceable tool but I would really like to have better quality glass. thanks.
