How to compare spotting scope quality?
Basic question........how does one go about comparing scopes in a dealers showroom? Most stores I know that sell hunting optics have a relative small area in which to view things through the scopes and spotting scopes. Even if one takes the scope outside, what is one to learn about it's light gathering ability during the hours that most retail stores are open? Most stores are not open during the hours that would allow one to compare different scopes as to their light gathering and clarity properties. Any suggestions and or tips in this matter?
