I've recently made the transition from European scopes (Zeiss), to Hawke and Sightron. From 25mm. to 30mm. tubes. (Before you ask, they fit my needs better).
Obviously my new measurements are in Imperial rather than Metric.
What really fails to impress is the literature which comes with these new scopes.
What, for example is 1.12"?? It's a ba55stard mixture of both measurements!
I can relate to 8ths., 16ths., and 32nds. of an inch but i'm struggling with decimals of an inch. My old Physics master would be rotating in his grave at high speed.
My wife says I'm allowed one rant per day, and i've just used it up. Pedant, Moi?
