5+ Best Digital Laser Measures (Buyers Guide)

What is a laser distance measurer?

A laser distance measurer is the modern-day equivalent of the tape measurer we all grew up with. As the name suggests it’s used to measure the distance between two points.

Between where you are standing with the measurer and the point you want to measure to.

The device is a small handheld unit consisting of a digital screen which displays the measured distance.

But not only can they measure the distance between point A and point B, but they can also now be used to calculate area and volume of a space such as a room, and to add or subtract given measurements.

A brilliant addition to the toolbox of an architect, builder, surveyor, engineer, carpenter, and of course the DIY-er at home.

The physics of how these gadgets work is probably not important in this context – suffice it to say that it is all done using lasers which measure the distance travelled by light in a given time as the lasers bounce off target objects. (See how it works)

So much easier than a tape measure, especially when you’re alone. And you can measure much longer distances with a laser measurer – up to between 100 and 800 feet depending on which one you buy.

How accurate are laser measuring devices?

Laser measuring devices are accurate up to 1/16th of an inch which is amazing. They are so accurate because they are using rays of light and light does not deviate from its path.

It will always travel in a straight line between points. So when you activate the device in your hand to emit a light ray  (or laser) pointed at a given target it will travel directly to that target, hit it and bounce straight back to the device in your hand.

That, of course, assumes that there are no other objects for it to bounce off between you and the point you want to measure to. The time it takes for the light ray to get back to you, recorded by the device, is then used by the measurer to calculate the distance to the object or target point.

Unlike the old-fashioned tape measure, any uneven surfaces or bends don’t affect the laser’s travel to the target object. That’s why these tools can be so accurate, even over very long distances.

Best Laser Distance Measurers

1. Bosch Digital Laser

  • Weight: 13gs
  • Accuracy of 0.2mm
  • Precision of 0.2 degrees
  • Up to 10 internal memory

Also known as a range finder, the Bosch digital laser distance measurer is a must-have for any DIYer or professional who needs to measure lengths, heights, distances, volumes, and angles with almost pinpoint accuracy. You can also use it to add or subtract measured values.

The amazingly light (13gms) tool has an accuracy of 0.2mm per metre, and a measurement range of 0.05 to 50 metres.

Not only does it replace your old tape measure, but it also does away with your spirit level because it has a built-in tilt sensor which can be set to a precision of 0.2 degrees. It can hold up to 10 measured values in its internal memory.

To assist with the physical process of measuring the PLR 50C has a positioning plate at its base end which can be folded out to 90 or 180 degrees and placed against edges or corners for easier measurement.

The screen shows you a list of the calculated measurements. And by using the Bluetooth ability you can create a picture of the space you’re measuring (eg the room itself in 3D) and the various calculated measurements you’ve accumulated in a diagrammatic format on your iPhone, smartphone or tablet.

Amazing! Bosch calls this function the Measure & Go App. You can convert the resulting drawing into a PDF file for sending to an architect, painter or builder, for example.

It features a 2.4-inch colour touch screen with Bluetooth and Help functions. The help section of the screen explains all the functions of the Bosch PLR 50C.

Being battery powered (3 x AAA batteries) it is totally portable.

There’s a lot more to explore with this laser measurer. It’s a very small tool which certainly has a lot to offer. And the Bluetooth function with the Measure & Go App is a feature you’re unlikely to find on many other laser distance measurers and truly does set this one apart from the rest.

How to choose best digital laser measure?

You'll want to consider these eight most important factors:

Range 

This is how far your laser tool can reach and give an accurate measurement. The minimum most models offer is about 100 feet, but the top end is usually around 200 feet. If you're a homeowner, 100 feet is more than sufficient. 

Accuracy

Obviously, no matter how big or small your job is, you'll want the accuracy to be spot on and you'll find various levels of accuracy from 1/8th of an inch up to 1/16th of an inch. If possible get a more accurate one, although this usually comes with a cost. 

Measurement Modes

You'll want to ensure your digital laser measure comes with various modes such as:

  • Area Measurement
  • Second Rate Measurement
  • Pythagorean Theorem
  • Volume Measurement. 

There is many different modes available to you, for example you don't just have to measure in straight lines, there is ways to measure distance, volume, circumference, area and others. 

Ease of Use

The easier a device is to use the better. Some models such as Bosch have a one button option which makes it easy for anyone to use. 

Others have all sorts of modes that will require you to read the manual before you start using them, to figure out how to use it.

Display

You'll want a good high quality and clear screen. Some cheap models have tiny screens that are impossible to read. Most common is a 2.4" colour screen, which I'd definitely recommend choosing if it's an option. 

Being able to tell what mode you're in at all times is important, likewise when reading the measurements, you wouldn't want to make a mistake. 

Memory

If you're doing a job you'll be pleased to know that most measures come with an internal memory that will record and store previous readings. Some models can only store 10 readings, while others can store up to 20 or 30. 

If you're a homeowner you can definitely get away with 10, but tradies and contractors probably want something with larger memory, but this will cost you a bit more money. 

Safety Rating

Measures usually come with a safety rating on a scale of 1 to 7 which describes how much the device is sealed against dust. This is the first of two digits. 

Home owners probably won't need to factor this in, but tradies might. 

The second digit is between 1 and 9 and indicates how water resistant the device is. Some devices will simply say waterproof, which is effectively a 9, meaning it's most watertight. 

Again depending on your use case, these may or may not be a factor to consider. 

Bluetooth/USB

Some models come with built-in bluetooth or a USB cable which allows you to connect to a computer or other device and download the measurements. You may need to pay a bit more for this feature but it can be handy if you're working with those digital measurements. 

Verdict

When choosing a digital laser measure it can be confusing, as there are many brands and models selling the same thing, each claiming to be the best. 


You as the consumer should consider buyer reviews as these are the best way to ensure you're not buying an inferior product. Brands like Bosch for example are well known but come at a cost, whereas cheaper brands may not be as well known.


After our initial research, we believe that the best digital laser measure is the Bosch Digital Laser, which is battery powered, comes with a carry case and has been used by thousands of people in Australia.
