There are also versions of the items that are adapted to marine environments. Such offerings generally have enlarged porro prisms, which means they are able to provide a wide field of vision, as well as a large depth of focus.
Meanwhile, they are fully waterproof, which is an obvious advantage given that they are used in such close proximity to large quantities of the liquid.
It is also possible to get them with thick rubber armouring as protection in case they are subjected to falls and other such things.
On the other hand, it is possible to buy such viewing devices that have been adapted so they are better suited to viewing the night sky. Such products are popular among those keen on astronomy.
And of course they come in a range of sizes, from large to compact. Indeed, they can be so small that they are able to fit into pockets.
So, whatever type of binoculars you are after, there is bound to be something to suit your requirements.
