Marine Binocular FAQ (Frequently Asked Questions)
What Are the Best Marine Binoculars?
Hooway and Steiner both create excellent marine binoculars although you can find equally good options from other brands. These are the leading brands in the field but also come at a considerable price.
The main elements to focus on are that it is waterproof & fog proof, has approximately 7×50 magnification, and can float. You might also want to think about the weight and how durable it is.
What Is Better: 7×50 or 10×50 Binoculars?
For marine purposes, 7×50 binoculars are better than 10×50 but it is the other way around for use on land. This is because the constant motion on the water makes it more difficult to focus with higher magnification.
7×50 means that the binocular magnifies 7 times and has a 50 mm objective lens. The magnification is how much larger the objects in your field of vision appear and the objective lens indicates how much light is let in.
For the second number, the more millimeters the better because you often deal with having little light when you are on a boat. However, for a better focus, a 7x is recommended over a 10x because the smaller magnification compensates for the moving water.
What Does 20×50 Mean on Binoculars?
20×50 means that the binocular magnifies 20 times and a 50 millimeters objective lens. With these two numbers, you can calculate the exit pupil – the size of the center of the eyepiece.
To calculate the exit pupil divide the second number by the first number. In this case that is 50/20 which equals 2.5mm.
How Far Can You See with 7×50 Binoculars?
It is difficult to determine the exact field of view just with these two numbers. On average though, binoculars with these specs let you see between 300 – 400 feet, depending on the exact model.
