What rangefinder binoculars exactly are?
This type of field glasses are technically telescopes that use laser beams in calculating objects' distance. They are navigation tools for hunting, astronomy, combating, sailing, land surveys, geographic data collection, and golf yardage measurement. There are models of field-glasses that can determine objects' distance of over 15 kilometers. Rangefinders could be sold separately, but multi-purpose binos are more efficient. We need them with a rangefinder in Archery, hunting, military, forestry, and wildlife watching are some activities. However, it's important to understand these basic terminologies before making a buying decision.
1. Field of Vision (FOV)
When you look through the bino lenses, the wideness of vision is its FOV. Usually, the FOV's calculation is a thousand-yard measurement. When you read configurations like 537 feet at 1000 yards on your glasses, it means the field of vision ('end to end distance') is 537 feet at a distance of 1000 yards.
The power of magnification and objective lens' size are important features. You might find 7×20 or 10×42 inscribed on your rangefinder added units. The configuration means magnification power (is 7 or 10), and the diameter (mm) of the objective lens is 20 or 42. Usually, the magnification levels range between 7X and 10X, but you'll need between 3x and 5x to watch movies.
3. Eye relief (ER)
The Eye relief feature is adjustable and has millimeter (mm) units. This factor tells the user the distance to maintain between the lens and eyes.
4. Optical performance (OP)
The clarity and sharpness of images seen through the glasses or prism determine its optical performance.
5. Maximum range distance (MRD)
The amplitude of the device's laser beam allows it to travel over long distances. Models with higher magnification powers offer more maximum range distance. The highest distance at which the field glasses can give accurate data is its maximum range distance.
6. The range of errors (ROE)
This factor is measured in percentage and shows the rangefinder's level of accuracy. When you have distance reading of 1000 yards from a rangefinder, and the ROE value is 0.8%; it means the actual distance is between 992-1008 yards.
7. Ballistic configuration
Sometimes the feature is written as 'B. Config' to show how well it supports the manual input of data.
The features that determine preferences may vary amongst buyers. However, you must ensure a comprehensive comparison of all the specifications before choosing your favorite pair of glasses. In the next part of this article, our experts reveal helpful insights that can guide your search for ideal bino-model.
What to know before buying?
Our research on different technological aspects of rangefinder binos can narrow your choice for products that'll suit your needs. So, consider the following factors before purchasing any model.
1. Binos vs. rangefinder binocular combo
Binos are designed to provide clear vision of objects with two optical tubes, lenses and prisms that are different angles. Models with built-in rangefinders are expensive because they carry high magnification powers with the least rating being a 7x. A rangefinder binocular combo is ideal for obtaining accurate long-range data. However, if you plan to own a product that gives short distance views, the rangefinder is better. They are more budget-friendly, and lighter. Unlike combos, they are stand-alone devices that bow-hunters use to aim their close targets.
2. Zoom vs. Fixed
Zoom models have adjustable magnification powers according to model's specifications. Usually, spotting scopes with adjustable magnification features are called variable models. For instance, '10-22 x 50 mm' on your binos means the objective lens' diameter is 50mm; while the magnification power is adjustable and zoomable from a range of 10 to 22x. On the contrary, fixed power bino-units are not zoomable and lighter than zoom binos. With a single power of 4x being the minimum, and the non-zoom model with 50x will need a tripod.
3. Roof Prism vs. Porro Prism
Naturally, the design of binos ensure that in-built glass prisms in each tube reverse the image of objects. Optical devices with roof and Porro prisms are the two most common types of binoculars. The roof prism designs are usually waterproof and are more durable than the Porro prism binos. Roof Binos are shaped like the letter H. They have narrow hinges between their optical barrels. Also, they are more expensive because of large magnification powers. However, field glasses with Porro prism are ideal for recreational users and usually not waterproof. Porro prism binos have wide hinges between their oculars.
What if you need field glasses for boating or marine use?
Marine binos are free from fog, water, and rust because of their nitrogen-purged compartments. GPS feature on marine binos helps you identify channel markers and targets in the water. If you need them for marine or boating purposes, they must have built-in digital compasses. Typical models for water use have 7 x 50mm design and produce crisp images.
What do the numbers mean?
The numbers on binoculars indicate readings of its sensors. Magnification power is how big your target objects appear through the lenses. Binos specification with 5x, or 7x, or 10x means the target object is five times, or seven times, or ten times closer from your eyes. However, lenses with higher diameter sizes will allow more light to go through, and produce brighter images.
Things to look for in a rangefinder bino unit
It's proper to know what contrasting features to consider before buying a pair with built-in rangefinders. However, you may not need such devices if you plan to hunt game animals at a close distance.
1. Optical performance
Manufacturers apply layers of coatings on lenses to increase the optical performance in these devices. The optical performance refer to the efficiency of the device to show images in optimum brightness.
2. Maximum ranging distance
There are decent models that can scout through longer distances and give you accurate data. It's the amplitude of the laser beam that controls the maximum ranging distance. Lasers are light energy particles that have far-reaching effects. This feature helps read information that matches the distance of objects.
3. Field of vision
Normally, the 'Field of Vision' feature refers to the calculation that's based on 1000 yards. Often the 'Field of Vision' configuration of 388 feet at 1000 yards. It means at a distance of 1000 yards; the product has a viewing range of 388 feet from your position.
4. Magnification and objective lens
It's common to find binos with magnifying powers of between 7X and 10X. For instance, the '7X' means that what you see has been enlarged by that number. The objective lens has diameters, and their sizes are in millimeters (like the 42mm and 50mm objective lens). Usually, models with objective lenses' diameter of more than 42mm are bulky to handle outdoors.
5. Data accuracy
Our field tests on different models show different degrees of accuracy. The rangefinder with laser beam gives accurate measurements. Models with high-end designs measure distances from the lens to objects. The elevation angles, coordinates, and temperature readings enhance the accuracy of data.
6. Ballistic configuration
When you find the 'B. Config' (Ballistic Configuration) sign, it means the bino-unit allows inputs and calculation of data. The 'ballistic configuration' feature is adjustable with options for the base or expert mode.
The 'WT' sign is a symbol of measurement for the weight. The weight of the models with large diameters is heavier than units with smaller objective lenses.
8. Comfort and ease of use
The ergonomics of the structure and building materials decide the comfort and ease of use of a model. Weight should not be too heavy since these glasses are meant to be highly portable.
Premium manufacturers ensure warranty seals for their products. When factory defects are seen in any unit after purchase, it can be replaced by the seller when there's a warranty.
Create a realistic budget that meets your purpose. The affordability of optical equipment depends on its performance, strength of magnification, quality of images and durability. A rangefinder field-glass unit is ideal for long-distance targets. However, you don't need these with range-finding tools to view targets at close ranges like watching birds on a tree.
11. Waterproof and Fog Proof Feature
Weatherproof field-glasses are durable because of their sturdy construction. However, the plastic seals around the objective lenses and coats on the body ensure water resistance.
Advantages of a rangefinder binoculars
1. The accuracy of range distance
Knowing how far you are from targets is a basic skill of professional hunters. Rangefinder binoculars offer accurate estimations when calculating maximum range distances. Even at 2200 yards, it's only a rangefinder binocular that gives reliable data on the maximum range distance.
2. Impressive optical performance
Superior viewing of close-up images is enhanced by using binoculars with range finding capabilities. By increasing the layers of coats on the objective lens, manufacturers reduce the risk of having distorted images. More so, layers of coatings on objective lenses improves the display of data when using these binos.
Disadvantages of a rangefinder binoculars
The price of binoculars increase when they have built-in rangefinder and high-end features. Beginners might lack the enthusiasm for outdoor activities when rangefinder binos are out of their reach. Most top-rated models are compact, and they carry premium prisms setups that are supported by technology. Usually, people make the mistake of buying rangefinder and a binocular separately, and later they realize it cost-effective to get a combo.
Embarking on expeditions in the wilds requires lightweight gears to make you feel comfortable. The weight of regular binos is lighter than range-finding binoculars. The difference is an absence of built-in rangefinders in the former. Also, two-in-one products have more weight than single binoculars. To feel comfortable while using binoculars, you should buy a binocular harness or padded neck straps.
In choosing the right model, you must consider the important factors I listed. Some important factors include the level of range-finding accuracy, waterproof, and maximum distance covering capability. Other factors are the prism design, visual sharpness, and durability.
Reviewing different models of binoculars isn't an easy task. However, our team of experts and volunteers have picked the best rangefinder binoculars for different purposes. While long-distant hunters prefer the Leica Geovid HD-B 10x42, the USCAMEL 10x50mm HD appeals more to beginners with low budgets.
Much to our surprise, we had found that no model from a few reputed brands like Simmons, Meopta, Rudolph, Boshile, SIG SAUER, and so on could earn a spot on our top 10 list. They failed to match our benchmark for one reason or another.
Instead of investing in expensive rangefinder binoculars to watch birds from trees, simply purchase one without a range-finding tool. More so, binos with an illuminated compass are the perfect products for marine observations and military training. Nonetheless, the marketplace has enough models that can match your preferences. Having confirmed the features of the above-reviewed rangefinder binoculars, we expect you to find the product that suits your purpose.
