My 1st spotting scope was a 'budget' option sold by Leopold. Basically, I learned that cheap spotting scopes really aren't much better than a typical smart phone camera, and their tripods are even worse - Complete junk. I mean, a typical $200 scope's 30x image is fuzzy, 40x is blurry and 60x is a joke.
At 100yds, you'll need something much stronger than a strong bino's 10x to see a 30cal target hole. So, save yourself time & money and get a decent glass that'll do the job for ya. IMO, a Vortex Viper's good enough and a Razor would be the last spotter you'll ever need.
