The modern market offers numerous types of binoculars for each purpose. The sea type is widely used by professionals like sailors, lifeguards, and fishermen. Any sea lover can buy well-made, advanced sea binoculars to keep an eye on the surroundings. However, not all the models are equally suitable for exploring the objects on the water. You can check the list of popular binoculars on alloptica.com. Here we provide a detailed guide on the sea models and their descriptions.
Briefly About Marine Binoculars
These devices, also known as field glasses, are two compact telescopes pointed in the same direction but united into one model. Marine binoculars are divided into two types as well. You can choose between the two options with different designs:
- For military use;
- For civilian use.
Standard models provide 5-8x magnification. They are usually handheld and waterproof. Since the vessel’s motion typically causes vibration (slight or substantial, which is based on the weather), sea binoculars have an advanced feature installed in the glass that keeps the image clear. Normally, these devices are designed for boats and ships. Marine glasses are a must-have on the board of a vessel since they help you stay safe. While there is no exact amount of binoculars that you should have on the vessel, it is important to have at least one with extensive functionality.
Buying Your First Binocular: What to Look For
If you don’t know where to start, here are a few simple rules. It is highly important to read this information before you buy any glasses that you see in a store. Here are the top-4 essential characteristics of binoculars:
- Diameter and magnification of the glass. The standard model has a 7x increase and is 50 mm in diameter. The box is entitled “7×50”;
- Fog and waterproof capacity;
- View area.
Let’s talk more about each feature in particular. You have to ensure that all of them match your specific demands for the activities you are usually involved in. On average, each model has a detailed description of these features on the package. If there is a lack of data, you can reach the developers or search for another option.
1.Magnification and diameter
You can choose between several standard options of lenses: 7×50, 7×35, and 8×50. The first number stands for magnification, and the second is for diameter. If you try to see something from afar with binoculars, you need to buy the type with a higher increase of the faraway view. While “7” is a standard digit, you can also find “8” or even “9.”
You might not need such a high number since the “7” is the most widely used one. However, with the higher increase, the object you want to see won’t be clearly visible. It can turn into something blurry. The lenses with a high magnification rate must also provide an enhanced brightness level. Brightness requires extra lenses, making binoculars bulky and heavy. Uncomfortable binoculars can make your hands shake, and it will be challenging to focus on the image as clearly as you intended.
This is why many experienced marines prefer the classic 7x strengthening. The diameter of lenses must not exceed 50 mm. This is the gold standard for any model, no matter if it is your first tool or not.
You have to decide which type of focus you need. Currently, there are only two options on the market. You can choose between:
- Center focus. The knob at the center changes the device’s focus. This is a classic model, which is beneficial for a team of several people since each person in your crew can adjust the view for themselves. You will find a wide range of options with a central focus on the market;
- Individual focus. It is simple to use and even more comfortable to hold. This type grants a better view of close objects. No matter whether you look at something at a short or long distance, you will see the picture clearly due to the higher resolution. Eye cups are movable here, which means that such models are beneficial for everyone with glasses. Yet, they are not water-resistant, and you need to change the focus each time you use them.
The view area is the width you measure from a specific point. It can be either in feet or meters, which is based on your location. This indicator usually points to the horizontal image that you see while observing via the binoculars and not moving the tool.
If you want to check the feet numbers, the standard measuring is the length of up to 1000 yards. The degree of view equals 52.5 ft per 1000 yards. You can easily calculate the required rate if you are familiar with the location. If you don’t know the territory well, pay attention to the fact that the bigger the distance that binoculars cover, the fewer details you will see. If you have increased magnification, you will have a decreased image. You need a wide area of view if you search for high-quality sea binoculars.
If you are going to use this device for a long time, you have to consider the possibility of getting tired. Your eyes will be overstrained when you actively stare into the distance, and you might get a headache. Professional marine devices have the wisely calculated length between the lenses and your eyes to provide you with comfort. You should pick the distance properly. If you need standard glasses, you have to make sure that the model you choose is made for you.
