How often have you held on to something familiar merely because it was something you knew? This may be the case with binoculars that sport a classic single hinge design, as it has been around for so long. The name comes from the fact that the two barrels of the binocular are linked with a single hinge. This is the standard binocular design and is the most common for many users.
The single hinge design is used in both Porro and roof prism binoculars and found in all price classes, which cannot be said for open bridge binoculars. They feature a single, long joint, and are used with either central focusing, or with focusing separated for each eye. In the last decades, the length of the hinge has been getting shorter and shorter, like on the Vortex Diamondback HD. This is also one of the advantages. Here are more:
Along with the advantage above, another one is that these binoculars prove to be sturdy and reliable. Many times single hinge binoculars tend to be cheaper to produce and consequently, cheaper to buy. If you are not willing to spend much money on a pair of binoculars, this is an immense benefit for you. Notwithstanding, the single hinge design models may not cost a lot, but they sure do look like a million bucks, as they have a classic design to them.
Many factors need to be taken into account before you go out and purchase the first pair of binoculars that you have had your eye on. The only big disadvantage of single hinge binoculars we can pinpoint at the moment is the limit towards a comfortable use when viewing, in comparison to binoculars with an open bridge design.
There are different styles of binoculars on the optics market today, and different styles suit different people. Binoculars with a single hinge design are more affordable than the open-bridge design ones. They sport the most common construction, and it is what most users are used to. It is true that one cannot go wrong with a classic, but if your mindset is “I like to hold on to what I know”, maybe you should still reconsider your choice.
