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.

Best Bushnell Scout 1000 Review

With hunting season coming up, a laser rangefinder becomes more than just another shooting accessory. It is a necessity for effective hunting. Sure, a rifle scope can provide magnification and an estimated range but for a quick and accurate measurement, a good laser rangefinder is a must. And if you’re not happy with shooting in flat terrain, a diverse topography calls for specialization. And although it is possible to calculate for the true horizontal distance of a target based on the terrain angle, swiftness is a key characteristic in hunting. You want that measurement as quickly and as accurately as possible.

This is why I usually look for rangefinders with a form of angle compensation. The Bushnell line usually has this option even if it does cost a lot more. I normally wouldn’t purchase the Angle Range Compensation or ARC technology of Bushnell for golf or target shooting but for bow and gun hunting, it seems necessary. I’ve tried the Bushnell Chuck Adams BowHunter and found it satisfactory so I borrowed another Bushnell device from a friend when I was training. He lent me his new Bushnell Scout 1000 with ARC Technology. Here’s how it fared so far.


Bushnell Scout 1000 ARC Laser Range Finder

Beneficial Features of the Bushnell Scout 1000

  • Built-in ARC Technology

I’ve already told you that the ARC technology measures the line of sight yardage and considers the angle of elevation/ depression when calculating distances. What you get is the true horizontal distance displayed as the “shoots-like” distance on the screen. No need for further manual calculations in your noggin.

  • Features Bow Mode and Rifle Mode

Although I rarely used the Bow Mode, it can range up to 99 yards which is pretty distant for bow hunting. On Rifle Mode however, this baby can range up to 800 yards and at times even up to 850 yards. The advertisement says up to 1000 yards but I find that too idealistic. Also in this mode, bullet drop is compensated for in the measurement and holdover mode is in inches.


Bow Mode

  • Offers Scan, Bulls Eye and Brush Mode

Isn’t this overkill? Not at all. I love how Bushnell created situation-specific modes to cover your hunting needs realistically. On Scan Mode, you simply hold down the button and the device continually updates your yardage. Now, for shorter ranges and smaller targets like prairie dogs, the Bulls Eye Mode ranges closer distances. And on Brush Mode, you are able to are through cover (i.e. a set of trees) and gives you readings of background objects which I use as a point of comparison.

Pros of the Bushnell Scout 1000

  • Very accurate readings

The Scout 1000 is an intelligent little device that thinks for itself. When I want the range of a target that’s further off but is obstructed by a bunch of trees or rocky terrain, it automatically provides me with the measurement of the more distant object. It does the same for closer targets and gives me the range of the object nearer to me. It also accurately measures both line of sight and true horizontal distance up to 800-850 yards.


A closer look at Bushnell Scout 1000 ARC Laser Range Finder

  • Rainproof body and lens

The Scout 1000 is layered with a Rainguard HD lens coating which makes it withstand rain, sleet, fog and snow. It also surprisingly provides a crisp image in low light conditions and despite the direct glare of sunlight. With a waterproof case to some degree, the Scout 1000 is your all-terrain, all-weather rangefinder.

  • Compact and easy to use

Weighing less than 7 ounces, the Scout 1000 is light weight and can be easily carried in your hip belt or jacket pocket. It’s slim, vertical design allows easy use and storage. Its ergonomic design allows for a more stable grip as well while the single operational button cuts out any complications I dislike in a laser rangefinder.

Cons of the Bushnell Scout 1000

  • Awkward lanyard

A minor disadvantage but for the nit pickers, the lanyard or neckstrap could be a problem. I don’t know how anyone is supposed to wear it so I gave up entirely and placed another one altogether.

  • A bit pricey

You literally get what you pay for. If your budget is within the $100 range, forget it and look at another brand like Simmons or Halo. But if you want angle compensation and all that, be ready to dish out an extra $100-$150 for this device.


All in all, I am impressed with the Bushnell Scout 1000. It is accurate, fast and versatile. I think this device will prove very useful in our next hunting trip. I would definitely recommend this to any serious hunter who may want to upgrade their laser rangefinders.

Amazing Facts About Laser Measuring Devices

Laser measuring devices work by bouncing off a laser light from the designated target. The time it takes to return to the tool translates into the measurement. These tools are extremely handy in obtaining far off distances or mapping through a location. With the specialization needed in various fields, these Class 1 lasers have transformed substantially into portable handheld devices. It has become common for laser measuring devices to stick with the classic point-and-shoot technology.

Types of Laser Measuring Devices

  • Electronic Tape Measures

Gone are the days where one can only measure distances as far as a tape measure can take you. Cutting both time and effort in half, this handheld laser device requires a mere point and shoot. Electronic rangefinders are perfect for long distances and quick measurements. These are preferred by engineers, architects, repair men and even cameramen assistants for their ease of use and of course, pinpoint accuracy. A number will include the Pythagorean mode where the device calculates the third side based on two measurements.

  • Laser rangefinders

From accessory to necessity, rangefinders are taking measuring distances to a whole new level and have upped the game in various fields including golf, shooting, hunting and archery. While pushing the limits of laser technology, a few rangefinders claim to measure up to 1000 yards. Apart from accurate readings at faraway distances, these devices take into consideration and even measure in increments of +/- 1 yard. A few will include an angle compensation feature that takes into consideration the angle of elevation/ depression of the target.

What to Consider in Choosing the Best Laser Measuring Device?

  • Need

Always consider what you will need a laser measuring device for. If it’s for repairs or anything related to infrastructure, an electronic tape measure is your best bet. But golfing in uneven terrain is a completely different story and will need a laser rangefinder to reach farther distances. In fact, identifying your needs can determine whether or not you even need a measuring tool that uses laser technology. For small repair jobs that are not done on an often basis, a manual tape measure will suffice. And shooting targets at short distances can be done with a rifle scope.

  • Accuracy

Some laser tools are more accurate than others. Whether it be rangefinders or electronic tape measures, the general rule is to compare and contrast. Try a couple of rangefinders or electronic tape measures side by side with a steady target. This is assuming you are familiar with your target’s distance. A good laser measuring tool will get the range spot-on on the first try while others will take a few more tries.

  • Power

Consider what you will use the laser for. If it requires great distances, choose a device that has enough power to provide readings that far. More powerful electronic tape measures can go up to 135 yards while the best rangefinders can give readings up to 850 yards realistically.

Of course, before any smart purchase, the price is also an important factor not mentioned above. It’s hard to appreciate a $400 laser measuring device if you’re not too sure of its features. Do your research by sampling as much of these tools as you can until you find one that will definitely suit your needs and that is within your budget.

Bushnell and Simmons: Spot the Difference

Life is full of options, one of which is having to choose between two brands. Most times, we ask, do brands matter, or are we mostly just paying for the label?

Brand names are important, but more than sticking to famous labels, it matters to know what each label is dedicated to. In the realm of rangefinders, for example, each model, series, and sometimes even brand names, are dedicated to some purposes (eg: hunting via archery, hunting via rifle, golfing)

Here, we’re going to know more about Bushnell and Simmons. What does each name stand for?

Bushnell Rangefinder

Both are big names in the world of rangefinders. But Bushnell is a name housing several series titles and models. The name has been in the industry for many years, and has built a name that could be equated to trustworthiness and accuracy in range finding. Among the series names are Scout 1000, G-Force DX, Elite 1-Mile, Truth Clearshot, Truth Primos, Sport, and Bone Collector. The first four of which are labeled premium, while the latter are on the budget end.

Bushnell G-Force DX ARC 6x 21mm Laser Rangefinder

Bushnell Tactical 202421 Elite 1-Mile ARC 7x26mm Laser Rangefinder

Bushnell also is equipped with varying technologies and modes, each fit for a certain activity. One of which is the ARC (Angle Range Compensation) Technology, where the angle of the shots are factored in on computing for the distance. It has a bow mode and a rifle mode, which stands for which hunting gear it fits to most.

The bow mode offers a shorter range, but provides angle compensated yardage. Rifle mode on the other hand ranges longer and still while considering the angle, but without giving out the data on angle compensated yardage. Furthermore, the Rifle mode has a VSI, an added feature that shows ballistic charts for choosing a trajectory that best fits the user’s hunting cartridge.

Bushnell’s are also equipped with Target priority settings, a Brush (2nd priority) and a Bullseye (1st priority) priority settings. The Brush option ranges the farther object, in case the reading reads two objects of different distance. The Bullseye option on the other hand, works the opposite way. The first priority option is usually better for long-range hunting, while the second one is good for golfing or short-range hunting.

Simmons Rangefinder

Simmons on the other hand, only has 3 different units, with almost the same features, varying only in the body’s appearance and LRF 600 Tilt technology.

Simmons rangefinders, unlike Bushnell, have a very specific target audience. They’re units are very basic and affordable, offering the best features that a bow-hunter could long for –without the extra features in other versatile rangefinders, thus allowing for more savings.

Most angle-related technologies are only available in premier to mid-range rangefinders for other brands, but Simmons offers it in a budget rangefinder. This rangefinder is basic but has good features for bow hunters. It may have a shorter range, but this is perfect for short-range bow hunting. Aside from the LRF 600 Tilt technology, Simmons is extremely basic. It has no extra features. There isn’t any bow or rifle icons, and no target priority options are available either.

Best Bushnell BowHunter Chuck Adams Review

Although I consider myself a novice rifle hunter, I still consider the quality of my key items for the hunt. With a Mossberg 464 Lever Action rifle, I don’t believe in spending for extra unwanted features. Sticking to the basic and really getting value for money is what dictates my shopping habits. Besides my rifle scope, I’ve been thinking about upgrading my shooting skills with a handheld rangefinder.  A few times during hunting season, I was able to borrow a buddy’s Wildgame Innovations Halo XRT Laser Rangefinder. It got the job done and I was able to hit still targets at a furious pace.

I was surprised last Christmas with a Bushnell BowHunter Chuck Adams Edition 4x 20mm ARC Bow Mode Laser Rangefinder, or BowHunter for short, by my mom. Although Bushnell has a reputation for pricey devices, I was relieved to discover that this didn’t cost as much as their deluxe golf rangefinder line. After giving it a go, here’s what I found in unison with what Bushnell has to say about their product.

Features of the Chuck Adams BowHunter

  • Measures LOS from 5 to 850 yards

    According to Bushnell, the BowHunter can attain line-of-sight (LOS) ranges up to 850 yards. That’s perfect for my long range shooting especially with a ranging accuracy of -/+ 1 yard. I also found out that this rangefinder caters to both bow hunting and rifle shooting although it specializes mostly with the bow and arrow.


Bushnell BowHunter Chuck Adams

  • Includes Bushnell’s ARC technology

    Bushnell’s Angle Range Compensation (ARC) is ideal for shooting at angled slopes adjusting the range displayed based on your standing position. So whether you’re hunting a deer from a tree or from an elevated/ depressed terrain, the BowHunter compensates the angle for you and provides you the true distance from 5 to 99 yards.

  • LCD Display

    All measurements (range and angle) are simultaneously flashed on the through-the-lens LCD display. So you can see through the lens and hit the “fire” button at the same time to achieve the range of an object.

Benefits of the Chuck Adams BowHunter

  • Has a built-in inclinometer

    Apart from displaying LOS measurement and true distance, the BowHunter also shows the user the angle of elevation/ depression thanks to its internal inclinometer. With an angle range of -90 to + 90 degrees and an accuracy of -/+ 1 degree, this hand in hand with the ARC technology provides a precise measurement of the target.

  • Up to 4 times magnification

    The Bushnell Chuck Adams BowHunter provides up to 4 times magnification. This is best intended for long range hunting and shooting. I find the 4x magnification ideal since it allows the hunter to focus on the target without being overwhelmed by the zoom.

  • Easy on the eye

    With multicoated optics, the BowHunter is versatile in diverse environments. This is especially apparent when it is particularly sunny outside. The Bushnell Chuck Adams rangefinder doesn’t have any problems with glare. Also the laser is a Class 1 beam (FDA approved) which is safe for the eyes.


Pros of the Chuck Adams BowHunter

  • Accurate even in diverse terrain

    I’ve tried ranging this and the farthest I got was 800 yards on flat land. It was spot on. But do keep in mind that it’s best to range nearby objects first to determine the distance of your actual target. I usually range a tree in front of and behind my target to estimate a measurement. The ARC technology has been praised in reviews and it is just as accurate as the flat land ranging capability of the BowHunter.

  • Compact and portable

    With a dimension of 1.4 x 2.9 x 3.8 inches, the BowHunter is easy to slip in and out of your jacket pocket or hip belt. At 5.3 ounces, it is lightweight and portable. I hardly felt it in my pants pocket when hunting.

  • Durable

    Another very handy feature of the BowHunter is it rainproof outer casing. I have also read in reviews that this little device can withstand a fall of 15 feet and still work fine.

Cons of the Chuck Adams BowHunter

  • Problematic in low light conditions

    Like almost all rangefinders, the BowHunter is troublesome at low light conditions. I attribute this to the black font displayed on the LCD screen. It may be visible on a sunny day but during overcast it can be a peeve. Also I noticed that the rangefinder stops performing in heavy fog. I do not recommend you use this in foggy environments. I don’t recommend hunting either.


Overall the Bushnell Chuck Adams BowHunterhas my vote. Despite a few knicks in low light conditions, it is still very accurate. The ARC technology is a huge plus to the serious hunter.  I would recommend this especially for bowhunting. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Certain content that appears on this website comes from This content is provided ‘as is’ and is subject to change or removal at any time without prior notice.
