Looking to get a new spotting scope this spring and need help on selection. Really trying to keep cost below $500. Unit will be used for hunting and target shooting at the farm (300yds - 400yds max). I know you get what you pay for but unless I sell a gun, I can not spend much over $500 this year. So far I have read good things on the following Bushnell 20-60x80 Legend Ultra HD, Leupold 15-30x50 Compact Golden Ring Spotter, Leupold 20-60x80 SX-1 Ventana Spotter, Leupold 20-60x80 Green Ring Seqoia Spotter (this one is discontinued and the closeout price is only about $350), and Vortex 15-45x65 Viper. Which one of the above would you pick or do you have another model in the price range? Thanks for the help.
