Laser Rangefinder: How Rangefinders Work

!±8± Laser Rangefinder: How Rangefinders Work

Laser Rangefinders have many different uses and applications and have become necessary equipment for different types of people specializing in different activities. Fact is that everybody that uses a rangefinder knows how easy they are to use and how beneficial they can be, although the actual dynamics of laser rangefinders and how rangefinders work is understood very little by those who actually use them. Rangefinders seem like quite confusing contraptions at first, but once you have an understanding about how rangefinders work, you will find they are quite simple.

Dynamics

Laser Rangefinders use an invisible, narrow laser that is pointed at an object to determine the distance it is from the user. The laser beam is then reflected off that object and back to the laser rangefinder instrument. The rangefinder then uses a super high speed clock to determine the amount of time it took for the laser to bounce back and then uses a mathematical equation to calculate the amount of distance between the rangefinder and the target object. The whole process is called "Time of Flight" in scientific terms.

Range

The distances at which rangefinders can effectively calculate distances can vary from 100 meters to up to 25 kilometers, and quite possibly much further if the investment warrants it. Generally the super long distance rangefinders are built for military purposes and used by snipers and artillery units.

The typical rangefinder the average person will have the ability to use will range considerably less than what you will get out of the military issue models, but that is okay because the average person will not need near the capabilities. For most people 1000 yards will be more than enough range to get the job done. Most laser rangefinders available to the public these days are rated to range in excess of 1000 yards.

Though a particular rangefinder may say it is rated to a certain distance does not mean that is what you will get out of a rangefinder. The maximum distance rangefinders will work will be dependent on the intended object's reflectivity and the current conditions. The maximum rated distance is what most manufactures put on the box and is figured in ideal conditions on a reflective object. On deer sized animals, you will be lucky to get 75% of the maximum range and less than ideal conditions will drop the effective range even more. This discrepancy is less with the more expensive models and greater with the less expensive models.

Optics

Most rangefinders will offer magnification of some sort in the form of a monocular (some are available in a binocular). The magnification typically ranges between 5 and 8 power. The quality of the optics will vary with the quality of the rangefinder, and again the more expensive models offer far superior optics clarity and magnification than do the cheap models.

Quality and Price

Quality and price have a direct relationship with each other when dealing with any sort of optics. Laser rangefinders are no different with price going up with increases in quality. There is also a noticeable difference between the low quality and high quality, and with laser rangefinders you definitely get what you pay for. That is why it is important to buy the best laser rangefinder that you can afford so there are no regrets.

Accuracy

Laser rangefinders are extremely accurate. Most will guarantee accuracy of plus or minus 1 meter. That is more than close enough for the average person and their needs, but this may not be good enough for commercial engineering or military use. For this, it is better to use GPS range finding techniques and triangulation equations.

History

Rangefinders have actually been around for quite a while; clear back into the 19th century. Laser rangefinders in particular, being not nearly as old, have only become popular to the average person in the last 20 years or so. They have been used by commercial and military operations for some time now, but these models were typically too big and heavy, and way too much for the average person to use on a day to day basis, not to mention they are much too expensive for the average person to afford.

How Does A Laser RangeFinder Work?

How Does A Laser Rangefinder Work Anyway?

So we point these things at our target, push the button, and it gives us a number. We know that there's a laser involved somehow, but just how do these things do it anyway? Turns out it's an old idea.

The same idea as sonar and radar

Just like sonar and radar, with a laser range finder you send something out and time how long it takes to bounce back at you. As long as you know how fast the thing you sent out can go, then you can figure out - with a little math - how far away the other thing that bounced it back to you is.

With sonar, you send out a sound wave. Like any kid who was taught how to tell how far lightning is, sound goes about a mile in five seconds. And just like all those WWII movies taught us, ships use the exact same principle by sending out a sound wave and measuring how long it takes to bounce back to determine the depth of that U-boat they're hunting. A more mundane common use today is the fish finder. Bats use their own version of sonar to fly and find prey.

Radar is pretty much the exact same thing, using radio waves. Those travel much faster of course, but it's the same principle - send out the wave, measure how long it takes to be reflected, calculate the distance based on the time it took. Other factors like the strength of the reflection and other characteristics can also give useful information, but that's another subject.

A range finder is like sonar and radar but using a pulse of light

A laser rangefinder works the exact same way, but using a focused, coded pulse of light in an eye-safe laser to do the reflecting and measuring. Like all light, it can be blocked by heavy rain, smoke, a twig, etc. The better range finders will include logic to let you select whether you want the first reflection or to ignore it if there's branches in the way, etc.

The rangefinder sends out the laser pulse and measures the time it takes to bounce back. All this is pretty much instantaneous to us, since light travels at somewhere around 186,000 MILES per second. But the machine can handle it.

Used in a variety of applications

Laser rangefinders are useful in many ways. They're used in hunting, golf, forestry, industrial applications, surveying, and of course the military. The M1 Abrams tank that I used to ride on back in the day had a very powerful laser range finder that would go out many kilometers.

Again, any rangefinder you would buy for normal consumer use would be eye-safe. The unit on that Abrams tank and other military applications? Not so much.

A key piece of equipment for hunting

One of the most important aspects of making a safe, ethical, clean kill while hunting is knowing exactly how far away your target REALLY is. There is no better way to do so than using a quality hunting range finder. This piece of equipment is fast becoming as necessary as camo clothing. And with the reasonable prices of high quality rangefinders, there just isn't much of a reason not to have on anymore.
