Hi Jason. Though unfortunately this shop (AOE) is closed, their website remains up. There is useful information in the articles on this page:-

The Andrews pair you are looking at should be pretty good. Coatings are discussed in the reference above. "Broadband"? - I don't know but maybe there is an answer here?

Edit - Found this:-
What does "broadband" mean?
Broadband is a type of multi-coating, and is the highest-quality multi-coating available from our factories. If you measure the reflectivity of standard multi-coating across the entire range of visible wavelengths (380-780nm), you'll see that reflectivity increases (is less efficient) at each end of the spectrum. Broadband multi-coating has less of an increase in reflectivity at the ends of the range, or in other words a "broader band" of efficiency, across the entire range of the visible spectrum. Note: Every pair of Oberwerk binoculars is fully broadband multi-coated.
ps. Get one of the metal L-brackets ($19) down the bottom of the page to mount the binoculars on a tripod.
