By using two separate lenses, rangefinder binoculars give users a greater sense of depth perception and allow them to measure greater distances more accurately. Additionally, these bins are lightweight and easy to use making them a perfect addition for any outdoor enthusiast’s arsenal.

This guide is designed to help you pick the ideal rangefinder binocular for your needs. Before we dive into features and types available, let’s first examine why these specialized optics can be beneficial for your outdoor adventures.

Explanation of what rangefinder binoculars are

Rangefinder binoculars combine two important pieces of outdoor equipment into one powerful tool. Also known as laser range binoculars, these binoculars use a built-in laser rangefinder to measure the exact distance to a target. This feature makes them incredibly useful for outdoorsmen, hunters, and competitive shooters who must accurately estimate distances of the targets they are aiming at. They also work great for measuring golf course layouts or other landscape characteristics that require accurate measurements down to several centimeters.

Rangefinder binoculars are designed with two lenses mounted on one body, allowing you to look through both barrels at once with your eyes open. The view in one lens provides the magnification power, while the view in the other provides an unobstructed field of vision for finding and measuring your target quickly and precisely. They also come with a built-in display that gives you an instant readout of the distance measurement for added convenience.

Importance of rangefinder binoculars

Rangefinder binoculars are an important tool for determining distances between different objects and landmarks. If you’re a hunter or outdoors enthusiast of any kind, rangefinder binoculars can be hugely beneficial for quickly calculating gunshot distance or determining the distance to an area in which you’d like to set up camp. They also provide greater accuracy than relying on visible estimates of distances between objects, as well as being more convenient and less taxing on your eyes.

Rangefinder binoculars work by combining a mechanical unit with optics that measure two angles, using trigonometry to triangulate the distance to a particular object. The angle at which the two lenses split is called the Inter-Pupillary Distance (IPD), and this easy-to-use device allows users to measure the exact distances without having to use complicated mathematical equations. This simplifies the process of measuring distances greatly, allowing outdoors enthusiasts and hunters alike to take full advantage of rangefinder binoculars for measuring distances quickly and accurately in any situation.

Understanding Rangefinder Binoculars

Rangefinder binoculars are a relatively new technology, combining traditional binocular optics with an advanced laser rangefinder into one device. This combination allows the user to quickly measure and observe objects from a distance by simply observing them through the binoculars.

Rangefinder binoculars are an excellent choice for activities such as hunting, birdwatching, wildlife observation and astronomy. They are also very well-suited for long-range observation or surveillance of terrain or buildings.

Unlike other types of optics, rangefinder binoculars include two key components: a pair of lenses and an electronic laser rangefinder unit. The lenses are usually fairly similar to those used in most traditional spotters or common field glasses, but they often have a wider viewing angle and better low-light performance than their non-rangefinding counterparts. The laser rangefinding module is what sets these binoculars apart and helps to accurately measure distances up to several thousand feet away in most models (check the specifications!). Additionally, some premium models feature advanced features such as integrated GPS tracking and compass navigation systems that can be very useful in unfamiliar areas.

In order to choose the best rangefinder binocular for your needs, you will need to consider factors such as size, weight and features before purchasing. It is important to be aware that although higher magnification will allow users to observe distant targets more clearly; higher magnification will also reduce clarity at close ranges due to its narrow field of view. Similarly, higher magnification requires larger lenses which can add significant weight (also known as “Creeping Weight”), so it is important not to overstep your needs when selecting your binoculars if you intend on traveling light!

What are rangefinder binoculars?

Rangefinder binoculars are an essential tool for any exploration or expedition. They are binocular optics that have been combined with range-finding technology to measure distances between objects or a user and a distant object. This is achieved by utilizing two main technologies – laser ranging, or through use of a primary reticle to measure the known angle of the object then multiplied by a constant ‘base range’ figure.

In many cases, rangefinders also incorporate digital imaging software and artificial intelligence strength capabilities so they can be used at night, in low light environments, or even indoors due to the IR LED (Infrared Light Emitting Diode) sensors fitted in the device. Rangefinder binoculars can come with enhanced capabilities such as an integrated GPS unit to help you record known locations and store them for later use when you’re outdoors.

These versatile devices can be used for activities such as hunting, surveying, sightseeing and birdwatching, among many others; this makes them ideal tools for travelers who like to explore nature. The primary benefit of using rangefinder binoculars is they make measuring distance easier and more accurate; this is particularly useful on sprawling terrain where it might not always be possible to ascertain exact distances through visual estimation alone.

How do rangefinder binoculars work?

Rangefinder binoculars use two techniques in order to measure the distance to a target. The first one is based on phase-shift, whereby the binoculars measure the time taken for a signal to be reflected back, and calculate the distance accordingly. The second technique is based on a mathematical formula (triangulation) that accurately calculates the distance based on two known values – the size of the object being measured and its angular position relative to you.

Each technology offers different functionalities, so it’s important to understand which type of rangefinder binoculars will best suit your needs. Phase-shift rangefinders are typically more accurate than those using triangulation as they can accurately measure smaller objects from greater distances. However, they may take longer to provide results due to their need for accurate calibration, particularly at great distances.

Triangulation rangefinders are usually cheaper and provide quicker results than their phase-shift counterparts, since they require less sophisticated hardware and take less time to calibrate. They also offer better accuracy at short distances while sacrificing some accuracy when measuring more distant targets.

Types of rangefinder binoculars

There are three main types of rangefinder binoculars available in the market: laser, GPS and Optics/Laser-combined.

Laser rangefinder binoculars use pulses of laser light to measure the target distance. The device then uses a special algorithm to calculate and display the target distance on its internal display. Laser rangefinder binoculars are very accurate, with a typical accuracy of +/- 1 meter when measuring distances up to 1000m. They are also the most expensive type of rangefinder binoculars available in the market.

GPS rangefinder binoculars combine GPS technology and optical technology for an accurate way to measure target distance up to 2000 meters away. They incorporate a built-in antenna for reliable signals from satellites, as well as an advanced optical system for precise measurements without fail. GPS units tend to be more expensive than laser models, but they are much faster and much more reliable under all weather conditions.

Optics/Laser combination binoculars combine both optics and laser technology in a single device, allowing them to provide more precise measurements while still being lightweight enough that they can be taken anywhere. These devices offer excellent optical clarity with greater accuracy due to their combined technologies, making them suitable for professionals who need higher precision than what is offered by regular optics-only models. While these devices tend to be much more expensive than regular binoculars, they are well worth their cost if you value accuracy above all else in your outdoor adventures or professional activities.

III. Factors to Consider

When selecting your rangefinder binoculars, there are several important factors to consider, including magnification, power source, objective lenses, field of view and exit pupil.

Magnification: This refers to how much larger the image appears when viewed through the binoculars in comparison to the unaided eye. Generally speaking, the higher the magnification the better; however it’s important to note that too much magnification can cause objects in your field of view to appear blurry.

Power Source: There are a few different options when it comes to powering your rangefinder binoculars. The most popular ones use either disposable or rechargeable batteries. Disposable batteries tend to be lighter and more cost-effective; however they must be replaced often. Rechargeable batteries often have a longer life-span and don’t need to be replaced as often; however they’re usually heavier and more expensive upfront.

Objective Lenses: This is what captures light from an object and creates an image that is magnified by your lens system in order for you to see it through the eyepiece. Rangefinder binoculars usually come with either 50mm or 42mm objective lenses as these are common sizes for these type of products.

Field of View: This is how wide an area you can see at once when looking through the binoculars from a distance of 1,000 yards away – usually expressed in feet per 1,000 yards (ft/1000yd). For example – “7×50” means 7 times magnification with a 50mm objective lens and a field of view at 1,000 yards wide will be 420 ft/1000yd – this is quite wide compared with other rangefinders! It’s important to note that higher levels of magnification may reduce your field of view – so select one that meets your needs while still providing an adequate amount of coverage you can use while out hunting or bird watching etc..

Exit Pupil:This is simply the diameter (in mm)of the light beam passing through each eyepiece lens – higher numbers mean more light gathering capability so objects viewed in dark conditions or at great distances will appear brighter compared with ones which have lower exit pupils (e.g 5 vs 4). An average value for decent quality rangefinder binoculars should be around 5mm for optimal performance.

Magnification and Objective Lens Size

When looking for a rangefinder binocular, the magnification and objective lens size are two of the most important factors to consider. Magnification is denoted by a number followed by an “x”, such as 10x or 12x. This indicates how much closer an object appears through the binocular. A 10x magnification means that an object appears ten times closer than it would with the naked eye while 12x magnifies 12 times farther.

The objective lens size is indicated by a number followed by millimeters (mm), such as 42mm or 50mm and looks like “20 x 42” or -50mm, for example. This number indicates the diameter of the frontmost lenses, also known as objective lenses, which let in light and play a major role in how bright and clear images look through the rangefinder binoculars.

Although bigger isn’t necessarily better in this case- since larger lenses can make binoculars too heavy; so it’s important to find a balance between magnification, objective lens size, and weight that suits your needs best!

Range and Accuracy

The range and accuracy of rangefinder binoculars is an integral part of what makes them so useful for outdoor activities such as hunting and wildlife watching. The two most important specifications for rangefinders include their maximum range and lens magnification.

It’s important to consider both of these features when choosing a pair of binoculars, as they affect the overall performance and capabilities of the device. The maximum range refers to the furthest distance that the device can measure accurately, while lens magnification determines how closely objects can be viewed when looking through the device.

In general, you should look for binoculars with a higher maximum range and greater lens magnification if you plan on using them in long-distance outdoor activities such as hunting or bird watching. For short-distance applications such as measuring golf distances or scouting wildlife, a lower magnification is usually sufficient; however, it’s still important to make sure your binoculars have enough sensitivity to detect small movements at great distances. Lastly, make sure that any rangefinder binocular you purchase has an accurate measuring system; otherwise, your results may be inaccurate or unreliable.


Drawing conclusions is an essential final step when making any purchase. You will want to make a decision that is based on the research and understanding you acquired throughout this guide. Here are a few tips for arriving at the ideal purchase for you:

  • Research: Take your time to research quality rangefinder binoculars online, read customer reviews, and ask questions of experts
  • Price vs Quality: Consider how much of a financial investment you are willing to make in proportion to the quality of product you will receive. It is just as important to determine what specific features are worth investing in.
  • Performance: Understand how certain features affect performance so as not to be overwhelmed with “bells and whistles” or focus too much on intangibles such as aesthetics.
  • Additional Considerations: Consider the size, weight, magnification levels, focusing range, and durability when making an informed decision on the best type of rangefinder binoculars to meet your needs.

As you can see, there is no one-size fits all answer when it comes to choosing the best rangefinder binoculars. However by taking this guide into consideration as well as doing some further research and engaging professionals in the field of optics if need be – you should have everything necessary at hand so that at some point in time – with enough due diligence –you can finally decide on the perfect set of optics for all your viewing endeavors!

Final recommendations for choosing the best rangefinder binoculars.

When it comes to choosing the best rangefinder binoculars for you, there are a variety of factors to consider. Before making your purchase decision, be sure to think about the following:

– Magnification: Look for binoculars with at least 7X magnification power. A greater magnification will offer you a better view of your target and help you measure distances more accurately.

– Lens Coating: High-quality lens coating will reduce glare and reflections, providing you with brighter images and clearer views. Look for models that have multiple layers of coating on both their front-facing and roof lenses.

– Eye Relief: Eye relief is the distance between your eye and the eyepiece lens where you will see the full field of view without vignetting or blackouts around the edges of your vision. The ideal eye relief measurement for rangefinder binoculars is 18mm or more – anything less may cause visibility issues. Choosing rangefinders with long eye relief will ensure that you get a wider field of view with clear imagery throughout.

– Size & Weight Considerations: Lighter weight models tend to be easier to transport while larger models are sturdier and provide more stability during use but can also become exhausting after prolonged use over time. When selecting size, think about how far you’ll be carrying it and how often. If weight is an issue, consider purchasing one with an adjustable body design so that it can be reconfigured when needed in order to reduce fatigue from extended use.

– Price Point Analysis: Consider your budget carefully before making a purchase decision – especially when comparing higher priced models versus lesser expensive options. Keep in mind that lower priced options likely won’t give you as many features or benefits as a higher quality model . Furthermore, many rangefinders come bundled with additional features such as laser distance measurement capabilities measuring capability that may affect pricing.
