I' ve got a pair of Tasco Rare Bird Falcons, which are 8x40 and are damned good glasses for the money. I ordered them based on some recommendations I got and they turned out to be great. I was chagrined, however, to find that nowhere on the binoculars is their magnification specification marked (8x40). What do I need to have on hand to prove the binoculars do not exceed rule speficiations?

I' ve got a couple pair of less expensive " compacts" that just don' t get the job done and don' t want to buy another expensive pair of glass just so I have manufacturer specs marked on them.
