So we’ve had a look at the Steiner Marine. Let’s now cover some aspects of choosing boat binoculars, so that you can make a more informed choice when looking at the models currently available for sale.
Why you need to have a binocular when boating
Binoculars are really a great help while you’re on the water, and even a necessity in many cases. Some may neglect the importance of having a pair of marine binoculars on board a boat, but, aside from recreation, it’s really a crucial item to have in terms of safety and survival.
For starters, binoculars can let you see spot and observe very distant objects. With these, you can see buoys, day markers, and lighthouses more clearly, as well as the direction and speed of other vessels, making them indispensable when navigating near the coastline or high traffic areas. That way they give you ample time to make a turn or avoid other boats and ships that might be coming your way to avoid collision. They also enable you to see any changes in weather, such as clouds or strong winds ahead of you, so you prepare or adjust course early on. Lastly, their recreational value is enormous: you can watch sea wildlife, observe the coast and even help you with locating fish if you’re out fishing, by spotting disturbances on the surface of the water, or birds flocking above.
How to choose the perfect marine binoculars
Choosing a pair of binoculars is not an easy task, but using them for boating, sailing and yachting puts even more constraints on the things you have to consider. For professionals and enthusiasts alike, these are the things you really need to look out for to make the best decision.
A binocular specification consists of two numbers. The first number represents the magnification power and the second number represents the diameter of its objective lenses measured in millimeters.
Let’s say we have a pair of marine binoculars sporting the common specification which is 7×50. As described in the previous paragraph, the first number represents the magnification power. In this case, the bino will magnify images 7 times compared to their original size. The second number describes the diameter of the objective lens. In this case, our hypothetical marine binoculars have a pair of objective lens with a diameter of 50 millimeters.
Keep in mind that the more you magnify an image, the less the brightness of the image will be. However, the wider your objective lenses are, the more light will enter your binoculars, thus making the image brighter.
That is why getting something 12×25 is a bad idea: the images will be dull. Plus, magnification above 8x is not recommended for use on the water, because it’s so difficult to keep them steady enough for a stable image.
Body and structural design
When choosing your optics, make sure that their body is sturdy, durable and can withstand any kinds of extreme conditions. As much as possible, choose a pair of binoculars that are waterproof, dustproof, shockproof and freezeproof.
If not, the moist air and unstable temperatures can cause your lens to fog up. There will also be instances where you will bump or drop your binoculars on hard surfaces. This is why you will need a product that is waterproof as well as shockproof.
Binoculars with waterproof design typically have an o-ring sealed interior and are filled with dry nitrogen or argon gas – this is to stop the moist and salty sea air corroding the seals. To complement the waterproof design, you may also want to purchase a flotation device (such as a strap) should your precious optics go overboard.
Image stabilizing feature
You will surely experience some rocking, bouncing and rolling movement while on the water, which makes for a shaky and blurred image. To give you steady and detailed images while in a shaky and unstable environment, you may consider getting a bino with a built-in image stabilizing feature.
Navigational features like compasses and rangefinder reticles can help you locate yourself and navigate in the middle of the sea. Usually an embedded feature, built-in compasses can help you obtain a bearing from an object that you can’t see while using a non-magnified handheld compass. Range finding reticles on the other hand helps you measure your distance from a certain object given that you know or you can estimate its height.
Modern binoculars typically have two possible focusing systems, namely center focus and individual focus. Center focus is the most commonly used among the three. Center focus is an arrangement that needs a rotation of a central focusing wheel for you to adjust both tubes simultaneously. Individual focus is an arrangement wherein the two binocular tubes are focused individually by adjusting each eyepiece.
Size and Weight
The size and weight don’t matter all that much when out on the sea. You will typically have your binos set on some surface and pick them up only occasionally. Commonly, marine binos are big to provide as much brightness and clarity as possible. However, if you use them frequently and hang it them on your neck, then you may want to get a pair of binos that are lighter so they won’t strain your neck in the long run.

This here is a special item to consider. You wouldn’t usually consider 12x magnification for marine use, but you definitely should in this case.
The best feature of this binocular, which makes it usable even out on the sea, is its image stabilization (IS) capability. The IS feature works by automatically correcting for any vibrations and motion in real time, and is powered by two lithium batteries that can last for up to 4 hours. To use the image stabilization, you only need to press a button.
