Why You Should Be Attentive to Your Device

Rangefinders are like devices that can give you super human powers. They can give you the ability to correctly and precisely determine the distance of an object from where you are standing from.

It even has the ability to compensate angles and other factors that a mere human cannot do with the use of their naked eyes.

However, just like any super powers that we see in the comics, rangefinders have weaknesses that could ruin its ability to do its job. Rangefinders needed to be taken care of properly to help them last longer and work better.

If it gets broken within its warranty period then at least you can have it replaced for free, but if the warranty period expires what then? You now have to be extra careful not to break its components, or let the environment damage it.

Here are some ways that you can maintain your rangefinders usability and avoid early wear and tear.

Things to Know to Keep Your Rangefinder at Best

1. Preserve The Device in Moist-free Places

Firstly, keep your rangefinder in a cool and dry place. Far devices like the Nikon 8397 Aculon AC11 have electrical components that are extremely sensitive tow water and moisture. That is why it is important to store them in places that are far away from water or moisture.

Place your rangefinder in a box together with dehumidifier beads to help absorb any extra moisture in its surrounding.

2. Clean Thoroughly Your Device After Each Used

Make sure to wipe the far device thoroughly after using it under a rainy weather. Most models are water resistant; however, rarely are they water proof. When your rangefinder gets wet, there is a great chance that water will seep through any small openings in your rangefinder.

Be wary of what type of cloth you use to wipe your rangefinder’s lens. Using the wrong type of cloth can severely damage the lenses of a rangefinder. It is incredibly tempting to wipe your lens with your shirt whenever it gets dirty.


Although some rangefinders are waterproof, you should still clean up carefully after each used to maintain best condition

However, the cloth of our shirt is often filled with dust and other dirt that can scratch the surface of the rangefinder’s lens.

That is why it would be better to always use a microfiber cloth or the cloth that often comes with the rangefinders like the Bushnell Tour V4.

3. Examine Detachable Components Regularly

Lastly, regularly check your rangefinder’s batteries. Rechargeable batteries used by rangefinders like the Nikon Forestry Pro Rangefinder have the tendency to leak as they get old. The chemical that leak out of a battery contains components that are highly corrosive.


If the leak gets into the sensitive components of the rangefinder, your device will become permanently damaged and beyond repair. There may be instances that you can have some components replaced but more often than not it can cost you almost just the same amount as buying a new one.

Generally Speaking...

Rangefinders are not cheap devices. They can sometimes take a good chunk of your savings. Getting it damaged can mean having to buy a new one thus you wasting money.

For you to avoid this from ever happening in the future, make sure that you take care of your rangefinder as much as you can and follow the given tips above.

One of the most important funtion of a rangefinder

Rangefinders nowadays are getting more and more advanced as time passes by. New functions such as the pin mode, zip mode, and angle compensation function have become bread and butter for professionals such as golfers, and hunters.


If one were to use any of these functions, they must fully understand how to use it and the principle behind that specific function. Misusing any of these functions is no different from not using a rangefinder at all!

In this article, we will discuss the proper way of using the angle compensation of your trusty rangefinder. We will also discuss on how your device calculates the adjusted distance with respect to the angle of your shot.


Anybody who has every used a bow, rifle, or golf club, knows that shooting and striking are not as simple as pointing your aim to your target. It is almost impossible to disregard the curvature the Earth’s gravity does to your bullet or golf ball. Whether it be a flat terrain of an angled one, without the angle compensation function, 40 yards is not truly 40 yards, and 400 yards is not really 400 yards either.

How it works

The angle compensation function works by taking into account two primary things. First is the angle at which you are shooting, a rangefinder with this function takes into account the fact that the more horizontal to the ground your shot is, the stronger the effect of gravity is on your bullet trajectory.


The second factor that your rangefinder takes into account is the distance at which your target is. Rangefinders equipped with the angle compensation function are programmed to take into account the fact that the margin of error of the true distance your bullet needs to travel from the direct horizontal distance you are from the target which gets larger as you get further.

How to use it

With modern day range finders equipped with the angle compensation function, using it is actually very computerized and simple. All you need to do is to point the range finder at your target and look at the “true horizontal value” that your range finder would indicate.

To understand the true horizontal value, imagine this situation. You’re aiming at a deer 50 yards away, you’re perched on a tree and pointing your rangefinder at the deer.

The rangefinder would then take into account the distance and the angle at which you are aiming, and tell you the amount of force you would need to use as if “the true horizontal value” is the actual value.

With you being higher than the deer, the range finder would tell you that you’d only need to adjust your angle as if he was closer. The range finder might say to compensate your angle as if you are only 30 yards away from him.


The angle compensation function has improved performance of everyone that has been using it. With this state of the art technology, you can assure that your aim and angle compensation is at its optimum.
