Any opinions on the Bushnell Sportview 20x60x60mm zoom spotting scope? I'm looking for a cheap spotting scope for my clubs 100 yard range & the local hardware store has one (Bushnell SV). I compared it to a cheap Simmons & another Bushnell 15x45x50mm & liked it. Are these of decent quality for casual target practice. I've been dealing with a foot problem since last summer & want to lessen the footwork while target shooting. Also don't want to spent lots of dollars. The above model is going for $89. Thanks for any info. Doug.
