Cheap ballistic chronograph, actually works really well.

- Testing out a cheap Chinese chronograph that I got from Aliexpress for only $35 plus $2 shipping. Amazingly it was able to detect very small pellets all the way up to very fast bullets. I don't have anything to compare it's readings against, but given how easy time over distance is to calculate, I assume it's readings are at least close.

I almost didn't upload this video. I'm self-conscious that I said "Ok" way too often and used it to start most of my dialogue...at the time of filming I didn't realize I was saying it quite so often. Anyway, it is what it is and I'm not going to remake this video, and as much as I don't like to hear myself, videos without talking are mostly a waste of time.
I did'nt notice , you talk pretty normal to me..
I am glad you did make the video, I was looking at this on Amazon to use with my Umarex Airjavelin CO2 arrow launcher before and after I do the hpa conversation, I want to accurately figure out the kinetic energy my arrows deliver. well made video sir. Thank you, I'll be buying this, it's all I need
@@MrMann703 I'm glad you liked the video. I haven't looked at the prices since I bought this unit a year ago, I imagine they are not as cheap as they use to be...but compared to other units, they are good value for money. One tip which may not be so important with large arrows, in really bright sunshine it sometimes doesn't see small bullets until you shade the unit from the sun.
@@timarulad here in Canada it is $93, about $70 cheaper than a name brand model that has a few extra features I don't really need. It along with a pen and paper is all I need lol
@@MrMann703 I just looked at where I got mine from, they are cheaper than the $93 you're paying, however you do have to wait up to a month and take the chance it arrives in one piece....I assume the person supplying yours has a business of importing stuff from China and selling it for a profit.
I bought one of these after watching your video & it working with .177 air rifle 👍,
my version does work in mps & fps,
When the display starts counting, press & hold the button, (display stops at 6)
release button (display shows nps)
short press button once,
(display shows fps)
press & hold button,
(led flashes red twice then changes to green)
release button
(display counts to 9 then shows su & beeps)
your in fps mode
you can also enter pellet weight to measure muzzle energy,
when the display shows SU,
short press the button,
(display shows 0.0 )
weight is set by short pressing button to advance the weight,
you have to set the weight higher than your pellet weight,
then reduce it by pressing the button just long enough for the led to flash twice,
say you want 4.5g set it to 5g with single short presses
then reduce it by pressing the button 5 times,
each time allowing the led to flash twice.
Thank you very much! I was having the same problem not finding the way to use it in FPS.
Now it works! And also I know it measures muzzle energy.. Thanks.
How the hell did you figure this out lol.
Much appreciated, a good no nonsense video ! It's hard to find decent folk on UA-cam who are not full of BS, your comments are perfect.
Thanks for your kind words, glad you liked it.
You have to push on button during the countdown after the "ON" have been displayed. If you push on it during 1111 to 5555 you access to the MPS/FPS setting and you just have to press a bit longer after you choose the right unit in order to store it (until the red led is brighting). If you press the button after 6666, you access to the weight (first - short press increase of 1g - long press decrease of 0.1g - very long press store it and pass to caliber setting and there the same short press to increase of 1mm - long press to decrease of 0,1mm - very long press to store it and restart) and caliber settings.
Nice video. Thank you very much.
My chronograph also came without any intruction paper.
But I´ve find the way reading coments here.
Mine has been working great. I accidentally shot it once and destroyed the on off button, very easy to replace. also you should keep the bottom row of LED receivers because it will have a glitch and measure ghost shots. I clean mine with compressed air from my compressor.
Just bought one.... no instructions but have got this far after two days:
House lighting can cause random triggering of display I guess same for sunlight affecting infra-red detection but as for the rest I am amazed it works fine and even has memory. Result it's a bargain.
The way I used mine is bellow, Used and OK to date.
Choice of Meters or Feet per second, and pellet weight (grain).
Switch on.
Chronograph boots up.
The display runs, press & hold button until sytem run is completed.
The run will end and display, 6.
Release button.
Displays mps. (If you require MPS, Press & hold button for 3 seconds.)
Short press button once.
Displays fps.
Press & hold button for 3 seconds. Release button.
Led flashes red twice then Displays fps.
Display runs to 9 then shows su (input pellet weight if wanted) and beeps.
You are now in fps mode.
Display shows - - and awaits pellets to be shot through detectors.
Pellet passes are indicated by two beeps.
Display shows speed of pellet.
Display returns to - - and is wating more shots or quick press of button to show speeds detected so far this session, and retained in memory.
Thanks for posting.
I took a chance on this low cost Chrono and aim satisfied. Have only tried it out with my pellet gun so far. The instructions are horrible, found out how to switch to fps from comments.
When it says FPS hold the button until the light turns red and let go. It'll switch over to FPS. When you power it off you have to set it to FPS all over again.
I've tried many different things since making this video, including your suggestion of holding the button when it displays FPS until the light turns red and letting go...but that gives me even lower readings (more than twice as low as the m/s readings). I also tried holding the button after the unit had "booted up" and there seemed to be some numbers that you can change by pressing and holding the button, like it's a way of calibrating the unit, but afterward the speed readings remain around the same as before.
It was a cheap unit, so maybe some features weren't included or they used a different processor chip.....given the current shortage of chips, this wouldn't surprise me, and the shortage might be the reason why the price has recently increased a lot for this unit.
I just got mine, entirely due to your video. I did just as Mike mentions and it accurately displays fps. Sorry yours isn’t cooperating.
If you're lucky, don't forget it's Chinese! 😋
@@timarulad When you turn the machine on it will always revert to MPS. Around the 2:00 mark of the video you did the correct procedure to change it to fps. Pressing and holding the button will then reset it and it will then display the results in fps. If you turn it off and on again with the switch (like you did in the video it will switch back to mps). I like to operate it in fps, so it is bothersome though to have to do this everytime you turn it on.
@@planezero It indeed seems that it doesn't have memory of any kind so every time the power switch is used, it resets to factory settings.
I must admit i was waiting for a cow to suddenly "go to sleep". apart from that it seems like a good product. I'd love to see a video of the insides of the device.
One thing you need to do is make sure the lights on the edges of the bar are lit, they can be blue or green etc.
This will need some fiddling around to get right but once it's done the unit will be working properly and will work very well indeed...
Once I have selected FPS, can you tell me how to get it ready to let a pellet pass through that will give a readout
Hi, I have a question for you:
With the two LED bars on top like that, can you also use it on an indoor shooting range with very little light?
to set the unit into FPS, when you power on the unit and it is count 1111, 2222, 3333 etc. press the set button while it is counting and it will go into the settings. then press the set button 1 time and let go. it will change to FPS. then hold the set button for 3 seconds till the LED turns green. now you are in FPS. you are holding the se button to long and that's way it will not change to FPS. If you watch the LED it will change colors, on your unit it will start as green and after 3 seconds it will turn red. when it goes red then let go the set button
I see that the device jumps when using the high-power rounds. I am assuming that is because you are using the same bench as a rest for both the rifle and meter, is that true? I am thinking that accuracy may be affected by that jump and that maybe not shooting from the same bench may help get the most accurate measurement. I sure do hope you will respond to this thought.
Hi, I have a question for you. Where do I get the app? A link would be great.
Thanks in advance.
When you set to fps, if the velocity is higher than 999.9 fps (above 1000) how display it? That is 4 digit count only.
The fps velocity reads in whole numbers over 1000. Same in MS . Mine reads up to 1320 m-s so far .
Yet gives up after 3 hours
@@paulsouth4794 Ok. Thanks. It display as 402.3 M (Mps)...like that
How far infront of the rifle do these need to be placed?
Were you able to Get it to read in feet per second?
Can you put the caliber and weight in it?
quand tu alume et que on apparait tu appuis 1 coup sur le bouton a gauche et il a une lecture en pieds
when you turn on and we appear you press once on the button on the left and it has a reading in feet
On mine, it states “number 5 batteries” in the directions and 1.5 volts on the battery Compartment (indicating AAA) however it also states AA in the directions and AA in the battery compartment that is for AA batteries. AA is all that fits and it will not come on. New batteries turned the correct way. Paperweight so far.
Why do you have to calculate to fps ?
Very good! Have you ever made a comparison with Crony for example? to see if I measured the same or similar. Brazilian hugs and greetings.
Thanks for watching my video. I don't have another chronograph to compare it against. Many years ago I borrowed one from a friend, it was a Caldwell, I only had the .22lr and .303 British back then. The .22lr did read around the same speed as I'm reading now and the .303 was slower, however that was with different ammo. My 6.5 Creedmoor ammo has a speed of 2,820fps written on the box for a 24" barrel, I got 2,778fps with a 22" barrel, so that seems about right.
@@timarulad Thanks my friend, thank you very much for the clarifications, the Caldwell chronograph is one of the most correct. Thank you very much.
I tested this one with my Caldwell behind it and they are nearly the same every shot.
@@WeGoOffRoad Thanks, good to know.
Power on hold the front button count to 20 release
nps should show on the display press button on front FPS should show up then press the front button again until a green light next to the front button flashes then let go should now be in fps mode.
Hav one my selves. Works grate. However, in sunlight it doesent work and have to be shaded with som cardboard or similar.
Mine was very inaccurate
So i got major ripped off.
DO NOT KILL THE ANIMALS INTHE BACK!!BE CAREFULL rUDI & gERMANY
What distance from the shooting bench?
This Chrony is very good.Not so complicate like users AND THERE IS MUCH PLACE TO SCHOOT IN:TOP:rUDI && FROM gERMANY
