Hey, it is using sound to measure the distance, the laser is just so you know the point at which it is measuring. It bounces a sound wave off the surface and times its return to calculate the distance. Laser distance measurement is pretty expensive.
The sonic measuring is referring to the ultrasonic waves that it creates to measure distance when you use the laser. The laser does nothing in terms of measuring and is only used as a guide.

The sonic measurement is how it measures the distance of the object you point the laser at. The laser is just so you can see what the "sonic" echo sounder is pointed at.
JJAM what's funny is that you can even here the device emit the sound in the video. Most acoustic measuring devices like this (cheap) only have around 30 feet in which they can get a measurement. LIDAR would be much more accurate and have a greater distance of read.

Now that you have a measurement how do you use the measure King to mark your piece of wood or whatever you need to cut? Also is it accurate on measurements? Other than that I loved the video but would need know more before buying the measure King still
At 6:19 the measure king uses ultrasonic measurement, not laser, the laser is just a reference for you to know what it's measuring. A true laser inferometer would be very expensive and bulky.
Thank you... I was about to comment the same thing. You can get a laser measure but they are quite a bit more expensive than any as seen on TV product.
@@MrJizzinmypantz Yes. It sends an ultrasonic pulse out and calculates how long it takes to return thus giving you the measurement. Since sound travels a lot slower it's less sophisticated to calculate and cheaper to manufacturer. We had these way back in the late 90s but they were more expensive then. Now we have a hand held laser measure .
On the tape measure king, it doesn’t measure using the laser. It measures using the sound, it sends out a sound we can’t head and waits for it to bounce back. The laser is just a guide to show you where exactly you’re measuring
It's called 'sonic measure' since it uses ultrasonic sensor to measure distance (like hc-sr04, laser is just for the guide to point at target. This is common misconception with measuring devices using laser pointers as a guide. Even in those non-contact thermometers laser pointer below the actual sensor is just used to point at targets (they use ir sensor to measure actual temperature).
Another example would be parking sensors in a car or truck. They work very similar but with no lasers as why would you need that:P The difference would be the cone pattern. Where a car sensor would have a wide field of view and a medium to short range this one could have a very tight angle and a further range though there is probably still a limit.
For the Measure King you left out the most important factor - accuracy. One review I found on youtube showed that the laser (sonic actually) mode indicated 27 inches while a regular tape measure was at 24 inches, with equally bad or worse results at longer distances - based on that alone, this is a fail, though the cord mode seemed fairly accurate.
There is sonic measurement on the Measure King - you showed it. The laser is just the aim for you to know the point to which the distance is being measured. Measurement itself is made with the ultrasonic device, which is shown on the box.
Beau Breard was gonna say the exact same thing. You’d think he’d realise you can’t measure something with a laser light unless the signal is returned to you
By looking at the measure king package it looks like the laser is just a pointer to see where you are aiming and it uses an ultrasonic sensor to measure the distance.
Dienekes yeah, sonar distance measurement is WAAAAY more common and cheaper than laser rangefinders. Considering you’re a tech guy I’m surprised you haven’t seen this arduino project everyone does
It is sonic, that's how they measure the distance without the cord or roller. The laser is just for you to see where are you pointing, the measurement is actually taken by sound. It emits one sound, and then counts how much time has passed when it reaches the device
the measure king has a sonic feature. The laser only shows you where are you pointing at. Then it releases a high frequency clicking voice and measures the distance by the eco of the voice (Doppler effect) That is why it does not work in bigger distances and in noisy environment. It also can show wrong reading when you have an obstacle in between.
Nope. Not the Doppler Effect. One or both of the measurement ends would have to be moving away from or towards each other. This device works via echo location.
On the measure king, the sonic read is what you referred to as laser. Yeh, it shoots out a laser to point with, but the distance is most likely done by ultrasonic pulses in the same way sonar works.
IT SEEMS THAT LOGIC STATES THE "SONIC MEASUREMENT" IS ACTUALLY LEGIT. IT SAYS "LASER GUIDE". THE LASER IS JUST A LIGHT SO YOU CAN AIM IT AT WHAT YOU WANT. IT'S NOT USING THE LASER TO MEASURE, IT IS USING SOUND WAVES TO MEASURE.
Laser has nothing to do with measuring. Just a pointer that points in the direction of what the sonic wave being measured is pointed at. Same as in the "gun" that you use to measure temperature with. The laser just helps you aim better.
There is NO Laser measurement on this! Measure king definately is NOT a LASER measurer.......Laser is to point to the point to be measured. It measures with sound. Echo"location". Hence the hole on the laser side. It is the pulse module and receiver. You shuold be able to hear a high pitched clicking from it.
sonic because look up sonic proximity sensors and etc, there is a way to measure distance with sound, that's what sonar is for. Edit: happy to see you are back and doing videos.
The measure King DOES have a sonic measurement mode. It is what you called the laser mode. The laser is simply a guide. It gets the distance using sonic waves. Light waves from the laser would be too hard to calculate on something like that.
That Measure King was tested by another reliable RU-vidr and he said that the readings are inaccurate and he gave it a thumbs down. You may have tested it and it seemed to have worked but you did not test it against a regular measuring tape to see how accurate the Measure King was. You failed on this particular test.
Yep, it is sonic. That presents some issues since a surface irregularity in-between the device and the object you wish to measure can result in false readings.
It definitely uses sonic measurement. That's how all of the range finders work. They work pretty well too. The laser is just a guide as pointed out by a few others here.
Re. Measure King: It actually uses "sonic measurement" when you activate that laser. See, the laser is NOT actually doing the measurement; rather, the laser is simply being used as a visual pointer for YOU to see and target the object to which you are measuring distance. The Measure King device then fires an ultrasonic sound wave parallel to its little laser beam, and an electronic circuit times how long it takes for the ultrasonic sound wave to echo back. This is how it determines distance. Another name for this technology is "sonar". Sound familiar? (Excuse the bad pun!) With the sound being ultrasonic (frequency higher than 20 kHz), humans can't hear it, and the sound waves tend to have very little spread, making the targeted measurement fairly accurate. Hence the need for the laser pointer, so human eyeballs can help you precisely aim where the Measure King's sound waves are being directed. Long story short: The packaging is NOT lying or being misleading; you need to brush up on your physics before you criticize.
I strongly suspect that the "sonic" feature is actually working. It would be much cheaper to build an acoustic ranging device over an optical one. The laser is probably only an aiming aid.
If you look on the packaging is says laser guide and sonic measurement so the laser is to guide you and it measures with the sonic emitter and reciver.
The most important issue with any measuring device is the accuracy of the measurements. Thumbs down for just playing with the measuring tape and not confirming whether it is accurate or not.
Regarding the Measure King. The laser light is just a laser pointer so that you can see what you are measuring at the other end. The actual measurement is done using an ultrasonic transceiver in the hole above the laser emitter. There are actual laser range finders but they cost a bit more and are more accurate.
The laser is just a guide the big circle above it is the ultra sonic sensor which sends sonic waves to something or an object and it travels back and thats how it measures a distance the laser just helps by letting you know what your pointing at.
The laser is just a guide for the users but the measure king uses sound waves that we can’t hear to measure how far away the object you’re pointing the laser.
I believe (and could be wrong) the laser on the tape measure is just meant to aim it. The measurement is being taken with sound. So the sonic measurement claim may be valid.
It uses sonic sound to measure when the laser is on. The laser is just so you can see where you are actually pointing the device. It uses ultra sonic sound which most people can't hear.
The measure king uses sonic not laser for the distance the laser is just a guide to see where its pointing at. to test this you could use a clear object like a window or something a laser guide would read past the window but the sonic would not
The sonic measurement could be real... if you read it carefully the box states that the laser is just a laser guide. It makes a lot of sense if the gadget really uses sonic waves to measure the distance while the laser is just a guideline, targeting the object you are trying to measure... But Sonar measurement would be more accurate
You didn't even fully test yhe measure king. They are garbage. The laser is not accurate and sometimes the wire measurement is off by a few inches. Just use a regular tape measure. They are never wrong
The measure king uses something called ultrasonic sound measurement, it uses sound to measure the distance, so the laser is just a guide, therefore the ultrasonic speaker is the real measurement device, the laser is only a guide to help the user.
It looks like the laser just points at the object that you are measuring the distance to, but that is just a visual guide to point at where the ultrasonic waves are aimed for measurement.
As stated on the package the laser in the measure king is only for guidence the actual measurement is done via ultra-sound. The us-sensor was clearly visible when you showed the laser. While it's not quite as accurate as a laser, it's still sufficient when you have to calulate in cut-off anyway.
It measures by sound ranging, not by laser. The laser is just a guide. As is described in the picture you hold into the camera. Also: "If you press the button, it throws up some arbitrary numbers which I will assume are accurate and give it a good review" Thanks a lot, such reviews I can do without.
as a note on the measuring device: the "Sonic" measurement is how it measures distance, the laser is just to verify what you are pointing at and dosent measure anything so the "laser measurement" is the sonic measurement
There is measure by sound actually, that is how bats can get sense of what is around them in the dark. Infact thats how speed cameras, ultrasound tests ( the gray screen which shows a baby in a mother's womb), and car parking sensors. All of these are essentially sound waves, they are just inaudible to humans.
The laser does not do the measurment. It is just a pointer for an ultrasonic distance measurement. That measurment is not acurate as the sound can bounce off uneven surfaces and cause it to be useless. Also as there is no reference surface on that tape you get a distance, but where is it to on the body?
@@GoatPirate420 It only measures length of and distance from babies. If it can "see" through objects like an abdominal ultrasound, that might explain why it's so inaccurate!
Yeah that’s what I was going to say!..lol The funny thing is I was going to buy it for my dad for a Christmas present......But I think I’ll get that lighter instead.
*on the device. it's meant solely on how it's advertised as having sonic measurement but hasn't to his understanding, not that sonic measurement doesn't exist at all. imagine all those poor bats, they would be blind af flying into everything in their way :(
I would have thought that a Sonic measurement is referring to sonar used for measuring against the wall as the laser is only a viewfinder on the wall to see what you pointing it
Trying to use the laser to measure a pulse of light at those short distances would require a very accurate timing device and would prove quite expensive hence why sonar os the preferred option
That's exactly how these less expensive "laser" tapes work. It's a sonic pulse with the laser only for knowing where you are pointing. There are high end professional laser measurement devices used by contractors and estimators that actually work using the laser, but these are hundreds of dollars.
