How Does a Laser Range Finder Work?

Describing how laser range finders work.

You slapped me awake when you said $49. I've been trying to find a deal on one for two years and sure haven't found one that cheap. $99 for an 800 is the best I've found.

Great job!! Clear, direct explanation, thanks !!

[GodGunsGears]

Got a bunch of these and never knew how they worked...great info...thanks for posting!

[Steve-Goff]

Thanks for the explanation. I've recently sold a few of these and had 1 guy ask me how they worked. I provided him more BS than anything

[aleksekokorev]

Exactly as i estimated that. Thanks a lot! 💪💪💪

[MonsterPumpkin]

Thank you! You saved me a lot of research

I SAW A VIDEO ON A RANGE FINDER HAD THE SAME QUESTIONS SAW THIS VID NOW I KNOW GOOD STUFF

[buckbuster]

Great price on it and cool tutorial on how it works!

if u put the lazer through a mirror that's at a angle will it get the distance to the mirror or will it get the distance from the mirror or the wall the mirror is reflecting it at

I have a question, what happens if you range find the lens of another rangefinder, will they both calculate the range?

[NoPatienceMan]

Good stuff! I will have an apple waiting for you on your desk Monday.

which camera was this video taken with? it looks fantastic

[Dug]

I got one built into a tape measure.
That it can differentiate the time difference between something and something else a 1mm further is staggering.
Considering light travels at nearly 300, 000 Km /second.
I could work out the time span to travel 1mm, but I think it would be incomprehensible..

What is the program or the algorithm that this device use

[scottf.]

Good info on how the rangefinder works...Good stuff...

[Dimaz]

I assume this thing wouldn't work properly in foggy, heavy rain, etc. that could make the laser scattered? 🤔

[solomonkullman]

The range finder knows what frequency it’s looking for, by knowing what frequency it isn’t

[TheTrackRecord]

Is what I’m confused about is it takes 3.3 nano seconds for light to travel a meter. Is the computer in that really fast enough to calculate that?

[jackammo]

Amazing deal for sure these are a blast

[damonleeb]

Crazy that’s gotta be more than millisecond configurations
