What do bird watchers and baseball fans have in common? The necessity for a quality set of dual-hinge binoculars. Binoculars come in different shapes and sizes, one of them being dual hinge, meaning binoculars feature a folding double hinge design. The barrels on such optics are joined together by a bridge in a double hinge fashion. The outcome is a perfect small foldable accessory to bring to a concert, a sports game, or a hike.
This type of construction is most common on pocket binoculars, namely so they can be folded and put into pockets – it rarely appears on any other types, as it does not make sense on, for example, full-size binoculars. As mentioned, the two joints usually take on almost the entire length of the binoculars, and this design enables the best and smallest folding size.
Dual hinge binoculars hit all the right notes: they use a double hinge design to fold down, making them ideal to stuff inside of a pocket. Their size when they are folded is the main reason for this design, making them appropriate for children as well, as they are also lightweight. Binoculars sporting this design also have an extremely flexible interpupillary distance, which is the distance between the centers of the pupils of the eyes.
When purchasing a pair of binoculars for trips, concerts, or star gazing, you need a pair that will take up the least possible space in your carry-on, but at the same time, not losing the needed optical features. However, if the binoculars are cheaper, they are prone to failure with time. They are also less comfortable to use in comparison to open bridge binoculars.
This design of binoculars fits into every pocket, as it is extremely small when folded. The dual-hinge proves to be excellent in the time of need – reaching into your pocket and taking out your pair of binoculars. This is very useful, especially if you come across a rare sighting you would not want to miss. Binoculars are useless if you leave them home due to them being too heavy, so dual-hinge comes in handy.
