Finally got around to getting one of the small bolt on barrel chronograph . And used this guy off Amazon. Arrived to me in 3 days . First day ordered it before noon, order processed by 4pm , next day at my local ups hub , arrived this morning at 9 am.
Packed well works as avertised .
So this chrony been discussed here but in a old thread and just wanted to update a thread on it for anyone interested in one with out going to alibaba/ china for one

Also here on page 3 from the old thread is translated instructions from Doug./lonewolf54

Anyway cost a few bucks more then one ordered from China but 3 day shipping made that little extra worth it (opinion)

Looks interesting. I'll have to check it out. Maybe as a portable option, instead of lugging around the Caldwell. Thanks for sharing

Seems fine. I jumped out side between rain and quickie test fired it and looked to do as advertised.
Only thing it's in meters per sec. So you have to convert to fps. No biggie. .
Unless something pops up or goes wrong on my next nice day to really use it I'm calling it good .
The big plus is the translated instructions that guy provided seems to be correct or good workable .
Also barrel mount makes it easy to point and shoot in any safe direction any place needed. Or just rest the barrel in attached and shoot unatached.
Anyway time will tell under use over the long run of it hold up or solid.

Mine has worked good for a couple of years.
Many others have had similar results.

Good deal
I tried to picture quick of it mounted and a test shot but I'll try in good sun
That shot was 247mps ( 810fps)

I've been using mine for about 3 months now and it works great. On my Avenger, I attach it with rubber bands. On my Prod the long metal clamp will go over the air tube and barrel shroud. I tried making a wood and metal adapter so I could put it on a little tripod but that did not work. The only drawback for me is it shifts my POI to have it on the shroud of the Prod - haven't tested that on the Avenger. So velocity and accuracy testing are two separate steps. The price is so low I don't see why any air rifle shooter shouldn't have one. You need a chronograph to tune your gun. I may still replace my old shooting chrony (that got shot one too many times testing inside with air rifles) so I can do accuracy and velocity testing in one step - outside when the weather cooperates. But I will still want this little one for inside testing or just for getting a quick reading without all the setup required for a caldwell or other more traditional chrony. While the FX has more features I can't see spending the price difference when this one works so well.

Good deal.
It's done what I need and when I'm not using it it's not a $100+ dust collector till I need it again .
Now I know my seal good after like 20,000 + shots with strings tight like this part of a 40 shot string all with in 3mps right down the line
I guess it's good? I was thinking1 or or 2 shots with a larger gap but nope.
What helped me with the buy was the guy in that old thread converting the manual to english . And had it at amazon with out going to china and waiting a month+ to get it , That made the deal.

Folks,
Last week I received one of the clamp on Chinese chronographs from Amazon. I'm not having great success with it. I clamp it to the barrel of my Beeman R7. I turn it on and it goes though a start up cycle and I get a - -. I cock the R7, load it, and shoot it. I may get a valid reading but usually I get a read of 18 to 40 meters per second. Occasionally, I get a reading of 200 meters per second and that is probably a good number?
I have read the translated instructions many times, am I doing some thing wrong? I realize the single button does more that just an on/off function.
I'm considering returning it to Amazon. I thought I would ask you guys that have one what might be doing wrong.
Thanks,
BobH.

Bob,
The only thing I can think of to check is to be sure it is mounted where the projectile will go over the two little sensors on the board. It apparently uses infared light to sense the projectile, not radar like the FX or visible light like a traditional chronograph. If the pellets are going over the sensors and you are not consistently getting a reading I would send it back. Mine has been pretty much flawless. I have not changed any settings so the velocity is only visible for 5 seconds but as long as I remember to write it down in that time frame, I have my reading.

? ? ? Tough call.
I also set mine on the bench unmounted and carefully shoot through it . So far at night or day it's been fine ,but once when cocking it if the full sun hits it just right it does flash something , it was too fast to read what it was . ( The sunlight activating it ?). I build and taped on a thin cardboard shroud / sunshields for the sides when it was in that full sun. Seemed to work but only tryed that one day seeing that issue but not noticed it since . (Shrugged shoulders and moved on)
Outside of that one thing I noticed it's been doing 10- 20- 40 shot strings. Heck I don't think I even had a error yet.
I guess if you had a 2ed air rifle/pistol to try and see what you get then . Same thing maybe a lemon works fine ?.?.?
Don't know how else you could test it off hand.
Edit
Just popped in mind someone did say with a 177 maybe line it up just right. Do to it's smaller size over the LEDs . I'm shooting .22 pellets.
Also don't forget you can set up a longer display time I set mine to 10s or something , but most time I shoot a string then go back and pull my readings each shot stays till you go to the next that way.
