Jag, I've 7 X 35 Zephyrs on my desk for observing ducks, geese, eagles and seals in our harbour. Working great for that purpose for 40 years, no complaints. For the blind, my 6 X 35 Watson-Bakers of Welwyn Garden City, Herts which I bought during my first job in the wage economy nearly 65 years ago are still a pleasure. Old optics serve general purposes as well as the new, in my opinion.
