We're often asked, what do the numbers mean on a pair of binoculars? If you're unaware, you're right to ask, as they're pretty important when it comes to choosing the optimum pair for your adventures. This is because there are different bins for different situations, from watching birds soar on the thermals and getting an intimate view of a resting butterfly to gazing at the crater-scarred surface of the Moon.
Much of that has to do with the numbers they’re labelled with, such as “8 x 24” or “10 x 42”. But, what do these numbers mean on a pair of binoculars? Well, unsurprisingly, it’s all to do with their optics.
