Both Hawke and Diamondback are respected manufacturers of excellent quality binoculars, but whichever model you eventually purchase, you have to visit a good camera shop, that also sell a large selection of binoculars.
The market is simply flooded with so many models, some a lot better than others, costing sometimes less money as well.
Our eyesight is ever so different, some of us wear glasses, and as we age, our eyesight deteriorates, so before anyone blows their hard earned cash on the first thing we like the look of, invest in a decent WH Smiths binocular magazine, and see what's on offer.
Just don't buy the first thing you see, as i can guarantee there will be better binoculars out there, for your eyesight, maybe costing less money.
