What to Look For When Buying Marine Binoculars
Porro vs. Roof
Porro prism binoculars are widely spaced and they have a bulkier design compared to roof optics. The porro system provides a greater field and depth of view. Roof binoculars are compact devices that make them more comfortable to hold but generally provide viewing for further distances.
Eye relief refers to the distance between your eye and the eyepiece. If you wear spectacles then this is the part of your binoculars that will be important to you. Some marine binoculars have collapsing eyecups to accommodate people who wear spectacles.
If you don’t wear spectacles the eye relief should feel comfortable to look through. Ensure your marine binoculars have the correct eye relief dimensions for your eyes.
Individual Focus or Center Focus
Binoculars come with focus mechanisms that allow you to adjust the clarity of your device. Most marine binoculars allow individual focus where one lens can be adjusted as opposed to both of them being attuned simultaneously.
The center focus is a traditional design where a mechanism is placed in between the lenses so you can adjust the clarity of both optics simultaneously. It depends on your personal preference but once the optics are adjusted they’ll stay that way until you readjust them.
Field of View
The field of view or FOV is the observable view an individual can see through an optical device. With binoculars, the FOV image you see will be measured by 1000yds. The measurement of view is equal to 52.1ft at 1000yds. If the FOV is too narrow it will affect your ability to track because you won’t have a wider view of the area.
The field of view can have a major impact on eye relief too. Wider eye relief dimensions will provide improved FOV. But it can affect clarity. Marine binoculars have an angular FOV between 6° and 8.3° to accommodate clarity as well as a wider viewing of an area.
As mentioned before, quality marine binoculars will come with integrated stabilizer technology so users can have a steady view when the boat is moving. With stabilizer technology, you’ll be able to see at further distances with crisp clarity.
Bushnell was founded in 1948 by David P. Bushnell. The company is situated in Overland Park, Arkansas, USA and it’s now a large developer of outdoor products and sporting optics. Bushnell provides reliable and affordable optics for various types of outdoor hobbies & professions.
