Bushnell H2O 7×50 Porro Product description
Of all the binoculars in the Bushnell H2O series, this 7×50 porro prism model is probably the best suited for use on a boat or yacht, especially if the water can get a little rough or choppy. As well as being waterproof and having a non-slip grip, the lower magnification makes it much easier to keep the image still, which when you out on the water on an unsteady platform, is really important to keep in mind. The large 50mm lenses are able to capture more light than smaller ones, which when combined with the 7x magnification produces a very large exit-pupil. This ensures an excellent low light performance and thus are perfect if you often go out in bad weather or before dawn and return just after sunset. The twist-up eyecups along with a generous 20mm of eye-relief offer a lot of space to work with an thus these also make a great choice should you wear glasses.
About Bushnell H2O Binoculars
The H2O series from Bushnell is a diverse collection of binoculars that includes a wide choice of both Roof and Porro prism models. As the name suggests, this is designed with water in mind and by that I mean they are tailored to either accompany you on the water in a boat, yacht or ship or be the instrument you can trust when out in the field and the weather turns nasty. In terms of their standing, this largely a value-priced range and will appeal to those shopping on a relatively tight budget, but require a good level of performance.
Important Features
As you would expect on a series designed to be used around water, all Bushnell H2O binoculars are naturally fully O-ring sealed and thus waterproof. These seals are also important in dry conditions, preventing dust from getting into the system. What is more, the air inside has been replaced with nitrogen to protect the internal glass surfaces from fogging. A defining feature on all H2O binoculars is the distinctive armour on the exterior of the housing. Not only for the protection of the optics that it covers, this highly textured soft rubber presents you with a very high grip surface to securely hold onto even wet, with or without gloves on. All models within the H2O series come with a centrally positioned, easy to reach, focus wheel, diopter adjustment, and twist-up eyecups to ensure they can be perfectly calibrated to your particular needs.
Optical Properties
The H2O binoculars are Multi-Coated which means that most, but not all the glass surfaces have a special anti-reflection material applied to them. This is usually the outer objective and eyepiece lenses that are coated and helps them transmit more light than untreated glass for a brighter and better quality view. However, it is important to note that whilst they cost more, higher-end binoculars like those in the Bushnell Marine series are Fully Multi-Coated meaning that every surface throughout the whole pathway is treated for an even brighter and higher quality image. With either Roof or Porro prism models to choose from, all are made from good quality BaK-4 optical glass.
Accessories
Depending on the exact model, but most Bushnell H2O binoculars come supplied with a soft carry case, padded neck strap, cleaning cloth and protective objective lens and eyepiece covers.
