Identifying Rangefinder Parts: Nailing the Art of Choosing the Right Rangefinder

Rangefinders work in basically the same way: laser is emitted from the push of a button, and this beam bounces off distant targets. The total time that it takes for the beam of light to be reflected back is measured by a high speed clock with the use of the speed of light for calculations. Thus, a distance is acquired.

Rangefinders are also made to be specialized in various purposes: hunting, golfing, forestry, low-light conditions, well-lighted conditions, and being outdoor and weather proof. There are a lot of factors to be considered, and features too. But for a general idea, let’s break down a rangefinder’s parts and see its relevance to a rangefinder’s value.

Rangefinder optics and its ability to spot a target


A rangefinders optics has to be at the top of your list when finding a rangefinder. One can never go wrong with a good set of lens. Most rangefinder specs highlight the magnification, ranging from 5x to 10x on the average. Higher magnification has the capacity to spot more distant objects, but that’s not all that matters. The quality of the glass is also very important in selecting a rangefinder. This is where most premium brands excel. A better glass could provide a better view and ease in spotting a target, compared to one that has higher magnification properties but lower quality. Both matter; in selecting rangefinder optics, take magnification and glass quality into consideration.

Data Analysis and Technology

Different brands and rangefinder specializations are equipped with technology that allow for: more computations that may be helpful to the user like slope for example, and other types of readings that all rely on the settings programmed in the device.  There are rangefinders that make use of black and red screen, to be used for low light conditions.

Other technologies are universally good for all tasks. Recently, most newly manufactured rangefinders are equipped with multi-pulse technology. An approach that makes use of small laser pulses in a very short period of time. This collects a large collection of readings, and eliminates fog, rain, and other objects that may be distractions in readings. More beams like this also increase the chance of spotting a small object, or an object with a non-reflective surface.

Rangefinders designed specifically for golfing sometimes have pin seeking features. Some features are very specific for some purposes. This is why it’s important to research thoroughly on what rangefinders could be capable of doing, and what of these tasks would you need, before purchasing a rangefinder.

Aperture size and eye piece


Aperture would also matter in how much data would be collected by the rangefinder. Since measuring distances would depend on light reflection, a bigger aperture would allow the unit to reach great distances and help improve the accuracy or resolution of measurements, no matter the distance. Another component that might be trivial for some is the eye piece. Check the eye piece before buying a rangefinder and see how it works for you. Some eyepieces have eye cups to ensure good focus on the user’s part. See if the lack of eyecup affects your targeting vision, or if the eyecup doesn’t affect your comfort in using the device.

In conclusion, a rangefinder has now developed to do various tasks.
